ABSTRACT Dehradun is one of the oldest cities of India famous for its natural beauty and hence tourism. But it has not been too long since it has been declared as the capital of the state of Uttarakhand. Ever since then, there has been a boom in the population of city. With this increasing population, there has been a considerable increase in the number of ve- hicles in the city leading to major traffic congestion especially in the cross road junctions. On top of it, there is an increasing demand for public transport which, as of now, is of very poor quality and also cannot cater to the current demand. In order to cater to present traffic management, the city largely lacks infrastructure. Thus, proper traffic management is the need of the hour. To cater to that need, intelligent transportation system is one feasible solution for it. Engineering INTRODUCTION The Intelligent Transportation System can be defined as the ap- plied use of various engineering disciplines, enabling technolo- gies and management strategies to facilitate modern transport operations and policy development. The Intelligent Transpor- tation Systems (ITS) are those utilizing synergistic technolo- gies and systems engineering concepts to develop and improve transportation systems of all kinds. The Intelligent Transporta- tion Systems Society advances the theoretical, experimental, and operational aspects of electrical engineering and informa- tion technologies as applied to ITS, defined as those systems utilizing synergistic technologies and systems engineering concepts to develop and improve transportation systems of all kinds. The Dublin City Council states that the intelligent trans- portation system involves the integrated application of a range of technologies, communications and management strategies to transport problems in order to increase the safety and effi- ciency of the surface transport system. The investment in ITS offers the potential of increasing the convenience, reliability and accessibility of all transport modes while also saving lives, time and money. APPLICATIONS OF INTELLIGENT TRANSPORTATION SYS- TEM Perhaps the most-recognized ITS applications, the Advanced Traveller Information Systems (ATIS) provide drivers with real- time travel and traffic information, such as transit routes and schedules; navigation directions; and information about delays due to congestion, accidents, weather conditions, or road repair work. The most effective traveller information systems are able to inform drivers in real-time of their precise location, inform them of current traffic or road conditions on their surrounding roadways, and empower them with optimal route selection and navigation instructions, ideally making this information avail- able on multiple platforms. The Advanced Transportation Man- agement Systems (ATMS) include ITS applications that focus on traffic control devices, such as traffic signals, ramp meter- ing, and the dynamic message signs on highways that provide drivers real-time messaging about traffic or highway status. The Traffic Operations Centres (TOC), centralized traffic man- agement centres run by cities and states worldwide, rely on in- formation technologies to connect sensors and roadside equip- ment, vehicle probes, cameras, message signs, and other devices together to create an integrated view of traffic flow and to detect accidents, dangerous weather events, or other roadway hazards. Another advanced transportation management system that can yield significant traffic management benefits is ramp-metering. The ramp-meters are traffic signals on freeway entrance ramps that break up clusters of vehicles entering the freeway, which reduces the disruptions to freeway flow that vehicle clusters cause and makes merging safer. The Intelligent Transportation Systems have a central role to play in funding the transportation systems of the country. The most common application is elec- tronic toll collection (ETC), also commonly known internation- ally as road user charging, through which drivers can pay tolls automatically via a DSRC-enabled on-board device or tag placed on the windshield (Stephen Ezell, 2010). An increasing number of cities throughout the world have im- plemented congestion pricing schemes, charging for entry into urban centres, usually at certain peak hours, as a means to not only reduce congestion but also to generate needed resources to fund investments in public transportation and to reduce the en- vironmental impact of vehicles. The Advanced Public Transpor- tation Systems (APTS) include applications such as automatic vehicle location (AVL), which enable transit vehicles, whether bus or rail, to report their current location, making it possible for traffic operations managers to construct a real-time view of the status of all assets in the public transportation system. This system help to make public transport a more attractive option for commuters by giving them enhanced visibility into the arrival and departure status and overall timeliness of buses and trains. This category also includes electronic fare payment systems for public transportation systems, which enable transit users to pay fares contactless from their smart cards or mobile phones using near field communications technology. The vehi- cle-to-infrastructure integration is the archetype for a compre- hensively integrated intelligent transportation system. Another application enabled by vehicle-to-infrastructure integration is intelligent speed adaptation (ISA), which aims to assist drivers in keeping within the speed limit by correlating information about the vehicle position with a digital speed limit map, thus enabling the vehicle to recognize if it is exceeding the posted speed limit. PRESENT TRAFFIC CONDITIONS IN DEHRADUN CITY The city, Dehradun is one of the oldest cities of India famous for its natural beauty and hence tourism. But it has not been too long since it has been declared as the capital of the state of Ut- tarakhand which was ripped out of the state of Uttar Pradesh as a new state in November, 2000. Ever since then, there has been a boom in the population of Dehradun city with people migrat- ing from different other towns and cities. Also, the city is a hub for education, both schooling and further. Hence, people from all over the country are expected to migrate to the city temporarily. With this increasing population, there has been a considerable increase in the number of vehicles in the city leading to major traffic congestion in the city especially in the cross road junc- tions like Ballupur and Chakrata Road. This congestion is not just due to the vehicles owned by the people residing in the city but also because of the vehicles visiting the city from nearby cities or states for tourism or business purpose. On top of it, there is an increasing demand for public transport which, as of
