Lane departure and forward collision detection plays an important role in autonomous driving and commercial driver-assistance systems. This paper presents an integrative approach to vision-based lane departure detection which aims to be as simple as possible to enable the real-time computation while being able to adapt to a variety of highway and urban scenarios on different weather conditions. In...
In recent years, traffic flow controlling and monitoring have become important issues in intelligent transportation systems (ITSs). For example, vehicle flow management can positively benefit the ITSs from accurate road vehicle detection and counting surveillance systems. In this paper, a high-accuracy vehicle detection mechanism with robust and adaptive vehicle mask training is proposed to effectively...
We present an intelligent bump system incorporated with the speed detection and dynamic license plate recognition techniques. The idea is to determine the enforcement of the speed bump based on the speed and identification of the vehicle. As a part of intelligent transportation systems for providing the traffic flow control, the proposed technique makes the driving safer and more comfortable. In the...
In Vehicular Grid Sensor Network (VGSN), because the operation of individual vehicles and mobile speed and direction, contact between them fragile and unstable. It has multicast links suddenly fail to overcome the problems, so that the message flows to each node, and increase the volume of traffic control. In this paper, we propose a fuzzy-based target tracking scheme that will re-route the link path...
Based on the digital hormone model, this paper established a new distributed coordination control scheme for traffic signals, which adopts some hormonal information. The experiments with a traffic network of 8 junctions shows that this new control method is obviously superior to the timing control, sensing control and real-time control.
This paper proposes a digital intermediate frequency (D-IF) receiver for inter-vehicle communications. Bandpass sampling is employed to lower the sampling rate. Appropriate selection of sampling rate and equivalent digital IF frequency results in a simplified Digital down converter (DDC). Meanwhile, the simplified DDC makes the combination of DDC and the following low pass filter (LPF) possible. This...
