Intelligent transport management system using sensor networks

Abstract

This paper proposes distributed traffic monitoring and controlling model using sensors and dedicated traffic servers. This model is described as basic role-oriented processes communicating though primitive interaction protocols. The model is aimed to provide an enabling communications framework upon which multi-agent system models can be organized and built to be used for an simulation of an road map and to estimate the traffic behavior (to provide information about the best routes). This paper presents a hierarchical routing strategy for controlling the traffic of that region. The model assists the drivers to get the desired destination taking into account the current situation of traffic characteristics. It gives the estimated arrival time and the corresponding distance between a start and an arrival point. The necessary information is obtained from current traffic position using sensors (used as dynamic information and to characterize the traffic, for example if traffic is jammed on an area, we can predict alter paths). The information given by the advisory system has the form of self generated message according to the condition of traffic using the given algorithm. The proposed algorithm uses well known searching techniques and data structures for appropriate handling of traffic in a sensor based web model for traffic management. To achieve this objective the model uses proposed algorithm on parallel communicating servers which also communicate with end users.

Sensor network for real-time vehicle tracking on road networks

“…6 Simulation experiments show that the worst case message loss is below 20% even in the case of very dense traffic driving beyond the safe speed range. This loss can easily be compensated by redundancy.…”

“…Recently the wireless sensor network technology gave a new impulse to the research on novel sensing, montoring and control techniques. [6] describes a vehicle and traffic monitoring solution, which uses both vehicle and infrastructure components. [7] reports a work on road embedded wireless sensor network, but it focuses on traffic characteristics measurements and vehicle classification.…”

Video based adaptive road traffic signaling

“…al. [4] developed an ITS using Wireless Sensor network (WSN) installing external hardware both on vehicles and roads which makes it complex and costly. We propose a video based adaptive road traffic light control method motivated by network data traffic control methods.…”
