2. CURRENT SCENARIO
 Independent traffic light controllers with pre-set
timings
 Traffic congestion leading to increase in travel time
 Possibility of emergency vehicles being caught up in
traffic
 Transportation infrastructure cannot be altered

3. PURPOSE
 Smooth traffic flow
 Unobstructed movement of emergency & VIP vehicles
causing minimum disruption of normal traffic
 Travel time reduction
 Increased road capacity without changing the road
layout

4. INTRODUCTION
 Traffic management using intelligent decisions based
on current traffic situation
 Sustainable & balanced transportation system
 Application of ICT in traffic management solutions
 Data gathering and provision of feedback
 Improved safety,energy efficiency,environmental
quality,travel time etc

5. APPLICATION
 Users’ perspective
 Green wave effect creation on roads with additional
feature of special vehicle pre-emption
 Target elements
Traffic light controllers
Message boards
Special vehicles

6. ASSUMPTIONS

ROAD
•Two-way primary and secondary roads
•Traffic volume in primary road is greater than in
secondary ones
•Special vehicles equipped with mechanism to notify
themselves to the traffic controller
