摘要

Wireless sensor networks (WSNs) are considered to be one of the useful technologies with extensive range of applications. Ramp metering is considered as an effective way to solve traffic congestion. In this paper, we evaluate some of the current solutions and study their effectiveness. Moreover, we develop a coordinated ramp metering technique that covers a larger area of highways within a city. This system composed of a set of ramps, ramp metering controllers, and a traffic control center components. In order to test and evaluate the proposed algorithm used in the system, a simulation is used on a network of road interchanges (named A, B, C, and D). The simulated results show that for interchange B, the time spent of traffic has been reduced by 34.4% compared to the normal case. 38% traffic flow improvement for Interchange C, and 41.6% improvement for interchange D.
