What is Traffic Optimisation ?
Methods by which “ time stopped ” is reduced.
Features
Case specific.
Real time traffic control.
Depends on the method adopted.
Depends to a large extend on the factors considered.
Selection of Technology- crucial step.
Why do we need Traffic optimisation ?
270,80,00,000 vehicles on road now !
Increasing at 4% annually.
Indian conditions
Total vehicles- 12,00,00,000.
Annual growth rate of 11%.
Roads already filled with 3 times
its capacity (Urban).
The most available practical solution is the optimization of traffic.
TECHNIQUES
Several techniques exist to reduce traffic time.
Algorithm designed to reduce delays, stops & other methods of effectiveness.
Many optimization software have been proved to be efficient.
AREAS OF APPLICATION
Emergency vehicle notification systems
Dynamic Traffic Light Sequence
Electronic toll collection.
Automatic road enforcement.
Collision avoidance systems.
Variable speed limits.
Vehicle information & control systems (VICS).
Advanced Cruise –assist highway systems (AHS ).
Advanced traveler information system (ATIS).
Advanced traffic management system( ATMS).
ADVANTAGES
Lesser delay time.
Maximum utilization of existing infrastructure.
Reduction in operating cost.
Better environmental quality.
DISADVANTAGES
It inherently favors motorized traffic over alternate modes such as pedestrians, bicyclists, and transit users and may promote more auto use.
The conceptual focus should be on the movement of people and goods rather than vehicles.
Conclusion
Traffic optimization using ITS represent the next step in the evolution of a nation's entire transportation system. As a result, it is expected that there will be an expansion of economic frontiers, balanced national land development, and the creation of a standard of living for the people such that they can realize a truly comfortable and affluent lifestyle.
