2. CURRENT SCENARIO Independent traffic light controllers with pre-settimings Traffic congestion leading to increase in travel time Possibility of emergency vehicles being caught up intraffic Transportation infrastructure cannot be altered 3. PURPOSE Smooth traffic flow Unobstructed movement of emergency & VIP vehiclescausing minimum disruption of normal traffic Travel time reduction Increased road capacity without changing the roadlayout 4. INTRODUCTION Traffic management using intelligent decisions basedon current traffic situation Sustainable & balanced transportation system Application of ICT in traffic management solutions Data gathering and provision of feedback Improved safety,energy efficiency,environmentalquality,travel time etc 5. APPLICATION Users perspective Green wave effect creation on roads with additionalfeature of special vehicle pre-emption Target elements Traffic light controllers Message boards Special vehicles 6. ASSUMPTIONS SECONDARY ROADPRIMARYROAD 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 7.
