Abstract

The applications of wireless sensor network in urban intelligent transportation system (ITS) were lucubrated, and an ARM9 SoC (system-on-chip) embedded sensor node was developed for urban traffic information collection and data transmission and reception. Together with the appropriate software programmed and intelligent control model for the urban traffic system built, the real time traffic data could be collected and processed for information distribution, and macro and scale coordination for ITS control within a city range through wireless sensor network that consists of this newly designed sensor nodes. Related algorithm for calculating the space occupancy and the congestion expectation for ITS purpose is presented, and the vehicle speed model is illustrated. Simulation results show that this novel ITS system based on the newly designed SoC embedded sensor nodes is practical and feasible. In addition, this system is also characterized at higher cost-performance, flexibility and control efficiency comparing to those ITS systems based on the Global Position Systems
