Maryland State Highway Administration
Maryland Transportation Operations Summit 2008
This Session is about• Focus on how agencies are effectively using
or planning to use technologies to improve operations (approach is to determine what is needed for better operations, then determine the optimum technologies; also using technologies as a “bridge” between agencies)
• Practice and technology in operation (… more innovative ways to address increasing travel demand)

Technologies to improve operations
• Too often we operate based upon the technology that we buy or build
• If you ask a geek or a salesman to solve your problems…he will!

Different Viewpoints...
The user view:
I want a Tree!!The programmer view: I know all about trees!
Maryland State Highway Administration

... with Bad Results!History shows…at the
end of the development effort, the user’s view seldom is the winner!
If you want to know what is needed for better operations, ASK OPERATIONS!!

Technologies to improve operations
• Accept that non-highway agencies need to know what you are doing
• Allow them to see what you are doing and have some say in how you do it
• Allow them (gasp) to share your tools that you use

Technologies to improve operations• There are multiple types of events available in
the CHART system:– Action Event
• Often used by Maryland Aviation Administration for parking messages around BWI
– Congestion Event, Disabled Vehicle Event, Incident Event• Used by State Highway and Transportation Authority for roadway events
– Planned Roadway Closure Event• Auto-populated by district offices through permitting system
– Safety Message Event• Often instigated by public affairs
– Special Event• Often used by Law Enforcement and Emergency Services

Innovative ways to address increasing travel demand
• CAPWIN
• RITIS
• Travel Times on DMS
• 511
• Expand CHART Capabilities to 3rd Party though common, secure IP protocols

Current CHART Sharing Solution
• Solution involves the extension of the MDOT network to the remote (non-MDOT) customer location
• Network, video and workstation equipment is installed on the remote site
• The equipment is not connected to the customer network• MDOT manages the network and PC equipment located at the
remote (non-MDOT site)• Security solution involves locking down the PC, MAC based
security and access lists• “normalization” of video between various codec formats is
handled via banks of decoders and encoders

Challenges
• Poor Security• Limited Scalability• Expensive associated with management of MDOT assets spread
out across the state in non-MDOT facilities• Cumbersome support for video from sources other than Coretec
encoders

Solution under Test
• Architecture is similar to the existing solution but includes the following differences– Establishes a strong security boundary between MDOT and
the 3rd Party customers via the installation of a firewall– Firewall configured to permit requests from 3rd party customer
to access the CHART application

Benefits• Does not require a small MDOT “island” to be created and maintained at the remote site
– Improves network security– Improves scalability
• Solution does not require dedicated PCs to be configured on the 3rd party network to access the CHART application
– Reduces the management responsibilities of MDOT– Improves operational usability– Improves security and scalability
• Management responsibility of all network equipment, PCs, decoders, etc that are beyond the MDOT firewall and the outside Proxy RP router will be the responsibility of the 3rd party
– Reduces the management responsibilities of MDOT– Improves scalability
• Use of video transcoders eliminates the need for legacy video switches as well as large banks of decoders and encoders
– Simplifies application development– Improves scalability
