GIS FOR TRAFFIC MANAGEMENT SYSTEM
BY SOURABH JAIN
Introduction
• Traffic management is the planning, monitoring and control or influencing of traffic.
• The Traffic Systems Management Program (TSM) is used to increase the capacity of State and local transportation systems by increasing the number of peak-hour person-trips by improving existing facilities without major construction.
Objectives
• Ensure reliable and safe operation of transport.
• Ensure fair allocation of infrastructure space (road space, rail slots, etc.) among competing users.
• Improving the travelling mobility.
• Conserving the energy while protecting the environment.
Need of Traffic Management
Role of GIS in TMS
GIS Plays Significant Role In Each Field Of Traffic Management. Some Of These Fields Are ………..
• Providing Alternate Routes To Road Users.
• Providing Necessary Information To Passengers.
• For Proper Signal Control.
• Minimizing Accidents.
• Reduction Of Congestion Spots.
ACCIDENT MINIMIZATION
• Accidents Can Be Minimize Through GIS By Generating A Data Base Of Most Accidents Prone Spots (Crash Spots).
• Information Can Be Provided Either In Tabular Or Graphical Format To The Users.
• Drivers Become Extra Cautious At Such Spots Hence Free Flow Can Be Maintained.
METHODOLOGY
• Load Pedestrian-vehicle Crash Data And Segregate The Data At Each Location
• Compute A Severity Index At Each Location.
• Examine The Spatial Patterns Of The Pedestrian-vehicle Crash Data.
• Create A Pedestrian-vehicle Crash Hot Spots Map.
• Load The Bus Stop Data And Identify Bus Stops In Hot Spots Areas.
• Compute Severity Indices And Rank Unsafe Bus Stops.
LOCATION OF PEDISTRIAL VEHICLE CRASHES
DISTRIBUTION OF SEVERITY INDICES
PEDESTRIAN VEHICLE HOT SPOT MAP
UNSAFE BUS STOP IN HOT SPOT AREA
PASSENGER INFORMATION SYSTEM
• Passenger Information System design for multi-modal transit system that integrates GIS, Network Analysis, user interfacing and database management.
• PIS gives answers to user queries like : Locations and street address
Optimum path based on time
Optimum path on cost
Optimum path based on dist.
Trip making information
Schedule of public transit
Fare Enquiry
Three-tier Architecture for Passenger Information System

CASE STUDY
A GIS Approach to Identify Road Network Improvement Needs By: Chandimal and Wijesekera
Study Area
Kaduwela region which is located in the western province of Sri Lanka
• Aim Of The Study Is To Identify Improvements That Should Be Made To The Road Network In Order To Reduce Wastage Of Time, Fuel, And Other Valuable Resources.
• GIS Is To Incorporates Spatial Variation Of Roads, Road Condition And Population In The Context Of Road Network Accessibility And Road Service Accessibility.
Methodology
Field data Statistics
Spatial Data Layers Used In The Study
Road feeder clusters in the study area
Proximity to Road layer in the study area
Pathway spatial accessibility
Affected road index values in different zone
Spatial accessibility indicator for project area
CONCLUSION
• The higher the Total Spatial Accessibility Indicator (TSAI) the higher is the easiness to access.
• The higher the ARI the higher is the need to provide assistance to develop the roads in a particular land extent.
• Higher the NPA higher would be the time taken to access a location through that a pathway.
• A simple model developed for Kaduwela area presented the potential of GIS in the assessment of accessibility, thereby identifying the zones with various degrees of accessibility.
