Dear Mr. -:

Here is the initial version (v1.0) of the manual, RITIS Website TechnicalManual. The RITIS website has become a powerful set of tools with manycomplex features and options that require a relatively high level of familiarityand general technical experience to use. In order to alleviate any possibleconfusion surrounding the operation of the various components of the

website for traffic management center operators throughout the WashingtonD.C. metropolitan area, this manual was written as a guide to its proper use.It includes complete written explanations for different sections of the sitewith step-by-step instructions for completing common tasks within them, andassociated figures illustrating the processes.

While this version of the manual covers the operation of nearly all of themajor sections of the site, the next version will include additional materialthat discusses the traffic data query tool, graph usage, and those sections of the site currently under construction that have placeholders in this version of the manual. During the time I was interacting with different features of thesite in order to write this document, I discovered several bugs and errors in

the system that should be addressed as soon as possible. Some of the moreserious errors actually prevented my access to features of the data archivethat I needed to explain in this manual. Hopefully we can schedule a meetingshortly to discuss these issues and have them resolved.

Though I was able to write most of this version of the manual from my ownpersonal experience in using and developing the website, it could not havebeen completed without the assistance of yourself and the helpful employeesat the CATT Lab. I would personally like to thank you for the in-depthwalkthrough of the website and sit-down time you were able to provideduring our meeting. Please extend my thanks to the employees as well.

Working on this version of the manual was an enjoyable experience thatgreatly improved my understanding of the different components of the entireRITIS project and its accompanying website. I am confident that the finishedmanual will provide the detailed information necessary to answer allquestions that may arise about the website. If you have any concerns orquestions please contact me anytime by phone at 240-446-8749 or throughe-mail at [email protected].



Sincerely,

RITIS Website Technical Manual

1 Introduction & Background

Information

The RITIS Website Technical Manual is the complete written companion to using theapplications embedded within the website of the Regional Integrated TransportationInformation System. It was originally requested to serve as a detailedinstructional/reference guide for new traffic management center operators surrounding theWashington D.C. metropolitan area that will use this system’s website. In addition, it willboth alleviate some of the current confusion of previous website users and provide thedevelopers of the website with specifications for the new features currently beingimplemented. Through the use of detailed explanations in combination with step-by-stepinstructions and diagramed figures, the manual clearly explains the purpose of each sectionof the website as well as how to properly operate the tools and features embedded

amongst the content. This manual is also written for several audiences that may not have agreat deal of experience working with the RITIS system or completing common computer-related tasks. As a result, the instructions in the manual are broken down into sets of verybasic steps that can be followed by all potential users accessing the site. It is organized sothat the major sections, and many of the subsections, found throughout the documentmirror the same organizational divisions of the website itself. In addition, an image of whatthe actual navigation bar from the website looks like when browsing a particular webpage isincluded at the top of the corresponding sections in the manual. By incorporating this imagebelow the headers of major sections the manual becomes much easier to reference andunderstand while actually browsing the site at the same time.

Remember: The “Click” action used throughout this manual refers to the standard left-

click of nearly all two-button computer mice. If the right mouse button needs to be clickedinstead of the left mouse button then it will be explicitly stated as “Right-Click.” The“Double-click” action is achieved by clicking the left mouse button twice in rapid successionwithout moving the mouse pointer.

1.1 RITIS & the RITIS Website

The Regionally Integrated Transportation Information System, or RITIS for short, is a $1.9million dollar ongoing project developed at the Center for Advanced Transportation

Technology (CATT) laboratory in College Park, MD. The major idea behind the developmentof RITIS is that the integration of traffic and transportation management data from the

participating organizations currently monitoring this information in Virginia, Maryland, andWashington D.C will improve general transportation efficiency, safety, and security.Currently, the information from these various organizations is stored and maintained locallyin formats that are often incompatible with one another, making it especially difficult fortraffic management centers in these areas to quickly and effectively coordinate theirefforts. With RITIS, however, this scatter data is fused into a single standardized source toprovide an enhanced overall view of the region’s transportation network that can be used toimprove operations and emergency response preparedness, support general transportationmanagement, and provide travelers with accurate regional information. The RITIS websiteserves as the central interface for accessing the consolidation of live and archived trafficand incident data for travelers, traveler information service providers, and participating

1



agencies that cannot already access RITIS data from their native systems. In addition toproviding contact information for all participating agencies, the site incorporates anautomatically updated list of all current traffic-related incidents and associated information,an interactive informational map system displaying live RITIS data, a powerful set of toolsthat can be used to query and analyze previously collected data stored in the archive, andseveral collections of automatically generated performance reports concerning variousaspects of the transportation network. The proper use of these various applications,including their numerous features and options, is the focus of the remainder of this

3.1 Incidents List

The Incidents List is a tool that provides information concerning the most recent activitieson the roads in the DC-MD-VA area. It is an important tool in receiving up to the minuteinformation about events that have just occurred. The list is constantly updated live in realtime as new events are reported to the participating agencies. It displays the state in whicheach incident occurred, its location, type, and time of occurrence. It also gives a brief description of what is currently occurring and a visual representation of which lanes of theroad are blocked (Figure 3 - 2). The background of the incident list alternates betweenwhite and gray to make it easier to read the different incidents’ information (Figure 3 - 1).When a planned event is scheduled, such as future construction or a football game forexample, the background of the event is colored yellow to distinguish it from unplannedevents.

The

incident list has a heading that displays information by state, location, type and time. The

State column sorts the incident list by the state that the incident takes place in. The

Location column shows the exact road and what exit is closest to where the incident took

place. The Type column displays the type of incident that occurred. There is a Time column

that shows the date and exact time when the incident took place (Figure 3 - 1). Each of these columns can be sorted in ascending or descending order, explained further in section

3.1.1.

• Lane Status is a useful feature of the incidents list because it shows the actuaconfiguration of road lanes and which lanes are blocked or affected (Figure 3 - 2).

• The lanes that are unblocked are displayed as black while the lanes that are blocked arecolored in red.

• The Description column will most often have a brief statement about the incident orevent that has occurred and will display any additional details that the poster had

provided, if any.

• The Timeline column contains a link to a popup containing additional details about theincident or event in an easy to read and informative format. The Timeline will beexplained in section 3.1.2.

Figure 3 - : Left portion of Incident List

Figure 3 - : Right portion of Incident List



3.1.1 Sorting the Incidents List

The Incidents List can be sorted by the various columns of data being displayed for each

incident. For example, they can be sorted alphabetically by the type of event and

numerically by time of occurrence (Figure 3 - 3).

• The information that can be sorted is indicated by the headings that are underlined(Figure 3 - 3).

• Click on a heading to sort by it. There will either be displayed a ↑or a ↓ next to theheading that is sorted. These signify whether the list is either in ascending ordescending alphabetical or numerical order.

3.1.2 Accessing the Timeline Display

The Timeline Display will show in-depth information about the incident that is selected.

When the Display link (Figure 3 - 4) is clicked a popup will be displayed showing the

additional information.

•

Located on the far left the timeline column contains a display link that when clickedwill bring up another window with further information pertaining to the incidentselected.

Figure 3 - : Preview of Sorting Columns



At the top of the popup the incident location is displayed and also what happened. There

are several different tabs that can be clicked on to expand. These will bring more

information about the incident.

The features on the Time Line display are used by clicking on the icon on the left side of the display box (Figure 3 - 5 A). When this icon is pressed the arrow will point downwardsand data for the incident will be shown (Figure 3 - 6). The various panes of information areused to find out what response units made it out to the scene, how many lanes are closed,and how the traffic is progressing through the area of the incident.

3.1.2.1 Using the Responders Tool. This tab displays the response units that have

arrived at the scene.

1) Click on the icon that is next to the tab labeled Responders (Figure 3 - 5 A). A window

will drop down revealing more information about the response units.

2) Using the mouse hover over the various dots that are located in the window. This will

display information about when the response units arrived on the scene.

Note: The table shows when each type of response unit first arrived and the length of time

that the response unit was present at the scene of the incident.

3.1.2.2 Using the Lane Status Tool. This tab displays a picture of the road andshows which lanes are open and which ones are closed.

1) Click on the icon that is next to the tab labeled Lane Status (Figure 3 - 5 B). A windowwill drop down revealing more information about the lanes of the road on which theincident has occurred.

2) By moving the mouse over a specified lane it will display how long the lane has beenopen or how long it has been closed (Figure 3 - 6).

3.1.2.3 Using the VMS Messages Tool. Stands for variable message signs; these

are the signs that signal to drivers if there is an accident up ahead or to turn to a particular

radio station for more information.

1) Click on the icon next to the VMS Messages tab (Figure 3 - 5 C) to view informationabout VMS messages.

2) This tab will go into detail about any messages that were put on display on the Variable

Message Signs (VMS) on major roads in the DC-MD-VA area.

3.1.2.4 Using the Speed Data Tool. This graph shows the traffic flow over the

most recent time interval.

1) Click on the icon next to the tab labeled Speed Data (Figure 3 - 5 D). A window will

drop down revealing a graph of the traffic flow over a given interval of time.

2) Hover over the graph with the mouse to show a window containing the x and x axis’

mouse coordinate (Figure 3 -7). The graph shows traffic flow on the y axis and is colored

to show the speed that the traffic is moving at.

Figure 3 - 6: Lane Status



Note: In the table showing in Figure 3 - 7 there is an edit button, this button is onlyavailable to certain registered users and is responsible for accessing databases of the CATTLab.

3.1.2.5 Using the Volume Data Tool. This window shows the volume of traffic that

is present.

1) Click on the icon that is next to the tab labeled Volume Data (Figure 3 - 5 E). A window

will drop down displaying the data on the volume of traffic that is on the selected road.

2) With the mouse scroll onto the graph to see the amount of traffic that is flowing on the

road (Figure 3 - 8). This graph is similar to the Speed Data window and is color coded to

represent the amount of

traffic also.

Note: In the table shown inFigure 3 - 8 there is an edit button, this button is only available to certain registered usersand is responsible for accessing databases of the CATT Lab.

3.1.2.6 Using the Icons on the Timeline Display.

The icons on the Time Line display are used by clicking on them; they are located on thetop right corner of the display box (Figure 3 - 9 A).By moving the mouse over these icons andclicking it will bring up additional information aboutthe selected incident.

• Click the icon to see more information about the incident if available. When the icon isselected a drop down window will appear as long as the mouse is kept on the icon.

• Click the icon to bring up a map of the incident. It will show the region that is affectedby the incident and what roads will be congested because of the event.

• Click the icon to print out the timeline display. This will give a printout of the varioustabs that have data on the five major windows in the display.

Note: Not all of the tabs in the Timeline Display will have information as not everything isavailable or reported immediately. But eventually all the data will be available after theincident has been taken care of.

3.2 Traffic Map

The Traffic Map provides users with a visual interactive description of all transportation-

related information concerning the Washington Metropolitan Area. The underlying mapprovides a bird’s eye view of the Metropolitan Area that includes details, such as generalregion labels and road names, which change based on the current level of zoom. Tools thataid in manipulating the map, as well as additional important information, are located in thevarious corners of the screen and will always remain visible.

Overlaid on top of the map itself are icons, images, and colored areas that are used tosymbolize the collaboration of live transportation-related information. Visible iconsrepresent traffic detectors, occurring incidents, and events that are placed on the map indirect correspondence with their actual corresponding locations. These icons and theirassociated data are grouped into various categories known as layers which can be

change based on how far the map is zoomed in. A scale showing the current level of zoomis located in the bottom right corner of the map (Figure 3 - 10 D). Note: At certain high levels of zoom the weather alerts and weather radar cannot bedisplayed. Zooming in too far will disable these layers, remove their associated visuals, anddisplay an error notification for a few seconds.

3.2.1.1 Moving Around with the Re-Center Tool. The map image can be moved

in any direction when the Re-Center tool is selected (Figure 3 - 10 A). This tool is initiallyselected by default. To move the map:

1) Click on the Re-Center button in the upper left corner of the screen to select thismode if it is not already set (Figure 3 - 10 A). Then choose to either:

• Double-click anywhere on the map to automatically re-center the map at that point.OR

• Click and hold the left mouse button down. Then drag the mouse in the direction themap should be pulled.

3.2.1.2 Zooming with the Mouse Wheel. To adjust the level of zoom based on the

center of the screen:

1) Scroll the mouse wheel upward to increase or downward to decrease the current zoomlevel.

3.2.1.3 Zooming In to a Specific Region. To zoom in to a specific region of the

map:

1) Click on the Zoom-Box button to select Zoom-Box mode (Figure 3 - 11 A). Themouse will change to a magnifying glass when hovering over the map in this mode.

2) Move the mouse to a corner of the region you wish to zoom in on.

3) Click and hold the left mouse button down.4) Drag the mouse to the opposite corner of the region you wish to zoom in on. A semi-

transparent red box will appear to indicate the approximate region you wish to viewupon zooming (Figure 3 - 11 B).

5) Release the mouse button to zoom into this region. The mode is automatically switchedback to Re-Center.

3.2.1.4 Zooming Out. To zoom out from the center of the screen:

1) Click on the Zoom-Out button located in the upper-left corner of the map (Figure 3 -11 A). The mode is then automatically switched back to Re-Center.

3.2.2 The Legend

The Legend is located in the bottom left corner of the map and is initially in its compressedhidden state. When opened, the legend provides the user with a quick glance at importantmap-related information:

• The type of clickable icons that mayappear on the map (Figure 3 - 12 A). Alldetectors, alerts, and traffic camera iconsare also clickable.

• A scale indicating the range of colors usedto illustrate levels of precipitation in theweather radar image. The light blue on theleft is the lightest level of precipitationwhile the dark purple on the right is theheaviest (Figure 3 - 12 B).

• An association between the colors of detector icons and the current average traffic

speeds monitored by that detector (Figure 3 - 12 C).

3.2.2.1 Viewing/Hiding the Legend. The legend can remain in its initial closed

state to reduce the amount of clutter on the screen or be fully expanded and visible when

desired. To do this, either:

• Click the Show Legend button in the bottom left corner of the map to make the legendvisible (Figure 3 - 10 E).

OR

• Click the Hide Legend button at the top of the legend overlay to make it retract andclose (Figure 3 - 12 D).

3.2.3 The Layer List

The Layer List is located in the upper right corner of the screen and is initially loaded in its

compact hidden state (Figure 3 - 10 B). When opened, this overlay provides access to thecontrols that manipulate each of the individual layers described in Table 3 - 2.

The ordering of the layers in this list determines the depth of that layer when it is displayedon the map. In other words, if icons from separate layers overlap when they are displayedon the map, the ordering of the layers in the Layer List determines which icon will bedisplayed on top of the other.

Note: The Weather Radar layer at the bottom of the list, when enabled, will always have itscontent on top of all other layers despite its unchanging position. The white background of this list entry indicates that it cannot be reordered like the other layers when adjustinglayer depth.

When a layer goes offline due to missing live data its associated icons will be removed fromthe map and an appropriate message displayed in the Layer List. When it comes backonline, the layer will revert to its previous state before going offline. If the Layer List isclosed when either a layer goes on or offline, the text of the Show Layer List button willchange to indicate what has happened until it is clicked to expand the list.

3.2.3.1 Viewing/Hiding the Layer List. The

Layer List can stay in its initial hidden state to

increase map visibility or be opened when access to

the layer controls are necessary. To do this, either:

• Click the Show Layer List button in the upper rightcorner of the map to make the list visible (Figure 3- 10 B).

OR

• Click the Hide Layer List button at the bottom of the list overlay to make it retract and close.(Figure 3 - 13 D).

3.2.3.2 Enabling/Disabling Layers.

Individual layers can either be disabled to remove all

of the associated map content or enabled to have it

displayed. To enable or disable a layer:

1) Click on the checkbox next to the layer name to

enable

or disable that particular layer (Figure 3 - 13 A).

3.2.3.3 Adjusting Layer Transparency. The transparency of all map content

associated with a particular layer can be set to one of five different percentage levels

(Figure 3 - 13 B). To adjust the transparency of a layer, either:

• Click the button to decrease the visibility of the layer content by making it moretransparent.

OR

• Click the button to increase the visibility of the layer content by making it lesstransparent.

3.2.3.4 Adjusting Layer Depth. The ordering of overlapping layer content, known

as layer depth, can be set by adjusting the order of the layers in the Layer List. Layers

higher in the list (closer to the top) will have their associated content displayed on top of

the content for layers lower in the list. To adjust the depth of a layer:

1) Move the mouse over the layer entry you wish to adjust in the list. It will turn yellow(Figure 3 - 13 C).

2) Click and hold the left mouse button down.3) Drag the layer entry either upwards or downwards to adjust its position in the list. The

other layers will automatically adjust their position and depth to give a preview of whatthe new ordering would look like.

4) Release the mouse button once the layer is in the desired position to set the ordering.

3.2.4 The Unmapped Incidents List

The Unmapped Incidents List contains a list of all of the traffic incidents that could not beplaced on the map as icons because they were not geolocated by the reporting trafficmanagement center. Each entry in the list contains the same information that would befound on the Incidents List page of the Transportation System Status section of the website,though in a more compact format. The Unmapped Incidents List (Figure 3 - 13) is locatedalong the right side of the screen directly below the Layer List and Unmapped Incidentsbutton. It is initially loaded in its compact closed state but will fill the remaining verticalportion of the right side of the map when opened via toggling the Unmapped Incidentsbutton (Figure 3 - 13 E).

If necessary, a scrollbar will be provided alongthe right edge of the list to allow one to scrollthrough content that may not be initially visible inthe overlay (Figure 3 - 14 B). To scroll, either click

the up or down arrows at the ends of thescrollbar or click and hold the bar itself whiledragging the mouse up or down.

If a new incident is added to the UnmappedIncidents List while it is open, then the text (new)will appear in the location column of that entry for

fifteen minutes. If, however, this occurs while thelist is closed, then the text of the Show UnmappedIncidents button will flash until it is clicked.

3.2.4.1 Viewing/Hiding the Unmapped

Incidents List. The Unmapped Incidents List

takes up a relatively large portion of the screen

and is initially in its hidden state to reduce screen

clutter. To toggle the list’s visibility:

Figure 3 - 14: Unmapped Incidents List

A

B



1) Click the button labeled either Showor Hide Unmapped Incidents on the right sideof the screen (Figure 3 -14 A) to make theUnmapped Incident List(Figure 3 - 14) appear ordisappear below

appropriately. 3.2.4.2 Sorting the List. The list of unmapped incidents can be sorted by the

location, type, time, and state parameters that are visible as links above the top of the

table containing the data. To sort the list:

1) Click the desired link at the very top of thelist to sort the data in ascending order by thatcategory.2) If desired, click the link to toggle betweenascending ↑ and decreasing ↓ order for thesort.

3.2.5 Accessing Detailed Information from Icons

All icons visible on the map, except those indicating road names or metro rails, aregeolocated symbols that give some indication of what current information is being gatheredconcerning that area. In addition, all icons referred to above can be clicked in order to openan in-map semi-transparent popup window explaining the details associated with that icon(e.g. exact traffic detector measurements). Sections 3.2.5.3 – 3.2.5.5 explain the differenttypes of informational popup windows that can be accessed from traffic map icons.

When an icon is first placed on the map for an incident within the last fifteen minutes, it will

blink to indicate its new status. Unless otherwise noted, popup windows display liveinformation and are updated on frequent intervals alongside the icons on the map.

Note: The popup windows referred to throughout section 3.2.5, unless explicitly stated,are really just formatted tables of information opened within the map application itself andare not actual browser popup windows.

3.2.5.1 Opening/Closing Information Popups. All clickable icons on the map have

additional hidden data that can be made opened or closed at any time, and will remain

opened regardless of layer status. To do this, either:

•

Click the desired icon to open a semi-transparent popup window containing additionalrelated information.OR

• Click the in the upper right corner of an open information popup window to close it(Figure 3 - 15 A).

Warning: Changing the zoom level of the map in either direction will automatically close allopen information popup windows. Take care not to accidentally scroll the mouse wheel andcause popups to be temporarily lost.



3.2.5.2 Moving Information Popups. All popup windows are initially opened with a

corner touching the icon that triggered it (Figure 3 - 15 C), though they can be moved to

anywhere on the map. To move an open popup window, either:

1) Move the mouse to an empty portion of the title bar of the popup to be moved (Figure 3- 15 B), not the .

2) Click and hold the left mouse button down.3) Drag the mouse, and now also the popup window, to the desired location on the map.

4) Release the mouse button to place the popup.OR

1) Click the icon associated with an open popup to instantly move the window back to itsoriginal position.

3.2.5.3 Incidents, Events, and

Alerts. The popup windows associated with

icons of incidents, events, and alerts (Figure

3 - 15) contain a formatted table of

information describing the typical details of what is occurring. The type of the icon is

displayed in the title bar of the popup window

while the body contains information such as

the location, time of occurrence, a

description, a graphical representation of

lane status if necessary (described in Section

3.1), and possibly a link to the associated

timeline that will open in an actual browser

popup window. If necessary, a scrollbar may

be provided inside the popup window to scroll

through the data just as in Section 3.2.4.

3.2.5.4 CCTV Traffic Cameras. The popup windows for the Closed Circuit Television

(CCTV) traffic cameras are fairly straightforward, containing only a textual version of the

camera’s location in addition to its live video feed. Once the popup window is opened, the

feed should automatically connect and begin streaming back the live video being captured

from that particular CCTV camera. Located along the bottom of the currently playing video

are basic playback controls similar to most digital media players, VCRs, and DVD players.

Clicking the pause button will freeze the video being streamed at the last frame

displayed. The play button will resume live feed playback from a paused state.

3.2.5.5 Traffic Detectors. The popups for traffic detectors will always contain the

textual location of the detector as a bold header at the top of the window. Located just

below the location is the direction of the roadway that this particular detector is monitoring.

The remaining displayed content of the popup, as well as the color of the detector icon

B



itself, will vary based on the status of the detector examined. The detector popups are

automatically resized based on the latest available data and thus should never require a

scrollbar in order to view the entirety of its content. The different types of detectors and

popups are described below:

Figure 3 - 16: The Three types of Traffic Detector Popup Windows

• Colored Detectors: All non-grey colored detector icons have received valid data withinthe last fifteen minutes and will display a summary of the last updated time, averagespeed, and average volume of the traffic passing this point (Figure 3 - 16 A). A smallgraph depicting this detector’s measured speed and volume of traffic over the past

twelve hours will appear in the popup window below the summary (Figure 3 - 16 B). Thissmaller graph can be clicked to open an expanded version in a new opaque popupwindow for easier viewing. The color of the detector is determined by the currentaverage speed reading as indicated on the map legend (described in Section 3.2.2) andstated below:

• : Current average speed reading > 50 mph

• : Current average speed reading 30 – 50 mph

• : Current average speed reading 0 – 30 mph

• Grey Detectors: A detector will turn grey once it has not received valid data for fifteenminutes. When this occurs, the summary of live speed and volume measurements in thepopup window is replaced by a red message indicating the time that valid data was last

received (Figure 3 - 16 C). However, the small graph depicting collected traffic data overthe last twelve hours will remain visible and functional in these popup windows just asdescribed above for colored detectors. Only when the grey detector has not receivedvalid data over the past twelve hours will the graph also be removed from the popup(Figure 3 - 16 D).

4 Address Book

The address book is designed to be a reference guide for the major response units in the

DC-MD-VA area. The list includes police officers, fire fighters and utility/maintenance

personnel. This comprehensive list is used to report problems that occur on the road thatneeds specialized response units to handle the incidents. The list can be sorted by location

or agency type (Figure 4 - 1).

Note: The Add Contacts tab is only for users that have access to the databases and areused to add new response units to the list. There will also be a searchable form added soonwhich would filter through the information by typing in a key word or name in a search box.

4.1 Sort by LocationClick on the sort by location tab to generate a list of various response units that are sortedby the state in which they are located. Under each state the response units are listedalphabetically by the counties which they service. The list provides the user with the phonenumbers for the various offices and whether or not the offices are open 24 hours a day(Figure 4 - 2).

4.2

Sort

by Agency TypeClick on the sort by agency type tab to generate a list of the response units that areseparated by their specialization. Listed under each type of response unit is a telephonenumber, the state in which they are located in, and whether or not the offices are open 24hours a day (Figure 4 - 3).

5 Data Feeds

Important: The Data Feeds section of the website is currently under construction and thuscannot be explained in this version of the manual.

When completed, this section of the website will offer a basic description of the available

data feeds that the RITIS project is receiving, including the various traffic data and incidentdata feeds from different traffic management centers as well as the weather advisories withDoppler radar from the National Weather Service. It will include information about how thedata feeds are formatted, if they are available for use, and also how to subscribe them. Aninteractive form allowing users to actually subscribe to the data feeds from this page of thesite may also be included.

6 Data Archive

The Data Archive section of the RITIS Website provides the region’s transportationoperation and research community with a powerful set of tools for both querying the

archive of information gathered from the various areas and performing secondary analysison the returned results. The archived transportation-related data collaborated fromdifferent agencies around the Washington Metropolitan area will serve as a rich source forboth traditional and innovative regional transportation analyses. In addition, the informationstored in the archives is a valuable record of decisions made and actions taken in responseto incidents and other scenarios that have occurred throughout this region.

Clicking on the Data Archive link will open the Incident Data Query Tool page by default,which is described further in Section 6.1. The Traffic Data Query Tool, described in Section6.2, can be accessed by clicking The Traffic Data Query Tool link just underneath the Data

Archive link header. As of this time, the Large Dataset Download subsection of the DataArchive Is under construction and will not be discussed in this version of the manual.

Warning: Both of the query tools mentioned in Section 6 of the manual are Adobe FlashApplications that require the free installation of Adobe Flash Player 9 or higher to properlyfunction. The latest version of the Flash Player client software can be found at:http://www.adobe.com/products/flashplayer/

6.1 Incident Data Query Tool

The Incident Data Query Tool is a part of the interface system that allows traffic engineersand researchers to easily browse through and visualize all of the incident-relatedinformation that has been consolidated in the RITIS data archives. Through the variousoptions available, analysts can quickly retrieve sets of data based on the different specifiedlevels of spatial and temporal aggregation. In other words, information can easily beaccessed in groups that are based on the time and/or location in which the incidents hadoccurred.

Warning: This tool will not function properly unless popup windows are enabled in yourinternet browser. See your browser documentation for information on how to enable popupwindows.
