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

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.
