Using traffic control scheme in intelligent transportation system

Abstract

Smart transportation is one of the rapidly developing fields among companies and researchers. Intelligent Transportation Systems (ITS), is a new transportation system which aim to resolve variety of road traffic issues, such as traffic accidents and congestion with cutting-edge technologies. Vehicular Communication Systems (VCS) is main part of ITS’s communication which is responsible for key distribution, key management among vehicles and security managers. To speed up key propagation and facilitate the calculation of crossing domain vehicles, there are different algorithms however only some of them consider controlling traffic flow. Traffic congestion has direct effect on key transferring so it is necessary to controlling traffic. In this paper, we proposed traffic control management scheme to characterize, controlling of traffic flow for increasing predictability of crossing domain and increasing safety with adjusting the acceleration of the vehicles. Parametric analysis based on manual calibration model with trial and error technique in mathematics is used to propose traffic control algorithm. At the same time two-way roads and different begin position for each vehicle have been measured. The results show controlled pattern, increasing predictability as well as decreasing key transferring time because of vehicles travel same amount of distance in domain.
