Since several decades ago traffic congestion has been increasing all over the world as results of. increased motorization urbanization population growth and changes in population density. Congestion reduces efficiency of transportation infrastructure and increases travel time air. pollution and fuel consumption Interest in ITS comes from the problems caused by traffic. congestion and a synergy of new information technology for simulation real time control and. communications networks Namely ITS is system to support transportation of goods and humans. with information and communication technologies in order to efficiently and safely use the. transport infrastructure and transport means cars motorcycles bicycles trains planes ships and. other as visualized in Fig 1,Communication technologies and services for ITS1.
ITS have been standardized and studied in various standards development organizations As an. international level ITU R ISO TC 204 and IEEE are working on developing the standards. Recommendations and Reports, In Asia Pacific AWG is working as a regional level as well as ARIB TTA IMDA TSAC and other. standard organizations in each country and region In Europe ETSI TC ITS and CEN TC278 are. working as a regional level, This Report identifies current and planned usage of ITS technologies frequency bands status of. applications and deployment, The major deployed ITS in the world were classified as electronic toll collection automotive radar. and vehicle information and communication In this Report are described applications overview. established standards frequency plan and implication in each ITS. 1 https www etsi org technologies clusters clusters transportation. 6 Rep ITU R M 2445 0,5 1 ITS radiocommunication, Electronic toll collection allows the manual in lane toll collection process to be automated in such a. way that drivers do not have to stop and pay cash at a toll booth ETC systems improve traffic flow. at toll plazas and the level of pollution by reducing fuel consumption In addition allowing traffic. to pass through the gate without stopping can increase road capacity by three or four times and. relieve traffic congestion at the tollgate It is also expected that ETC systems will reduce the. operating costs of toll roads by replacing manual toll collection. Since 1996 Vehicle Information and Communication System VICS has been used in Japan for. delivering traffic and travel information to road vehicle drivers. Nowadays to extend beyond the existing ITS applications and to achieve traffic safety. enhancement and reduce the environmental impact by the transportation sector vehicle to vehicle. V2V vehicle to infrastructure V2I infrastructure to vehicle I2V communications are studied. According to this progress ITU R WP 5A has developed a Report on advanced ITS. radiocommunication2 In the Report legacy ITS and advanced ITS are classified by their technical. characteristics as shown in Table 1 Wireless Access in Vehicular Environments WAVE and. Continuous Access for Land Mobiles CALM technologies and ITS Connect could be inclusive in. advanced ITS category,5 1 1 Terms and definitions,Terms and definitions are given in Table 1.

5 2 Automotive radar, Automotive radar facilitates various functions that increase the driver s safety and convenience. Examples are given in Fig 2 below, Exact measurement of distance and relative speed of objects in front beside or behind the car. allows the realization of systems which improve the driver s ability to perceive objects during bad. optical visibility or objects hidden in the blind spot during parking or changing lanes Radar. 3 https rosap ntl bts gov view dot 3984 pg 17 The V2I and I2V range was found to significantly exceed. original estimates In open field conditions with no roadside furniture the V2I range was found to exceed. 800 m and the I2V range exceeded 1 200 m using transmit powers of 11 dBm and 15 dBm respectively. and the low profile vehicle dual antenna, 4 https www nhtsa gov DOT NHTSA NRD Multimedia PDFs Crash 20Avoidance 2006 Vehicle. 20Safety 20Communications 20Project 20 20Final 20Report pdf Appendix G describes detailed. testing of WAVE communications in conditions including traffic and various roadway surroundings for. vehicles in motion various power levels and data rates In particular refer to 4 1 3 4 1 6 pp 101 107. 8 Rep ITU R M 2445 0, technology has proved its ability for automotive applications for several years Automotive radar. systems are of two categories according to the applications and frequency band. Adaptive Cruise Control long range radar usually operating at 76 GHz band This. enables a vehicle to maintain a cruising distance from a vehicle in front. Anti collision short range radar usually operating at 24 GHz and 79 GHz bands This is. being developed as part of a system to warn the driver of a pending collision enabling. avoiding action to be taken In the event where collision is inevitable the vehicle may. prepare itself for example by applying brakes pre tensioning seat belts to minimize injury. to passengers and others,Automotive radar,5 3 Global Navigation Satellite Systems in ITS.
It is common knowledge that devices installed in cars used by motorists employ the use of satellites. to pinpoint their location anywhere on the earth There are also numerous mobile applications on. smartphones making the service more accessible that make use of Global Navigation Satellite.
