Along with the economic development, cities are increasingly congested in China. In order to eliminate peak-hour congestion, many cities establish priority lanes such as bus lanes and Olympic lanes. Although priority lanes could help Local Authorities gain its short-term management objectives, at the same time, it would greatly infringe on the legitimate rights of other vehicles and waste the scarce...
To develop a quick detection algorithm for the image-based autonomous vehicle (AV) or computer assisted driving system, this paper proposes a real-time object detection method using two coordinated cameras. The mapping between two simultaneous images from the two cameras and coordination of the virtual sensitive areas can be resolved using parameters like the camera shot angle, the camera focal length,...
It is a timeless and actual problem to develop vehicle's active safety. In case of commercial vehicle category more sophisticated difficulties could be found. Increased mass and inertia are the fundamental differences between a usual passenger car and a truck. At the same time, the low series number requests cheap solutions. The aim is in this way to ensure low cost solutions to control increased...
The initial real-time information system for Bus Rapid Transit (BRT) is based on Global Positioning System (GPS) in Ji'nan, it can't provide accurate real-time information of buses arrival/departure at stop, and missing data of GPS is often found, especially under elevated highway or in bad weather. The papers put forward a new way to provide real-time transit information for BRT based on GPS/Signpost...
The paper presents aspects concerning the modeling, driving scenarios and control structures of two classes of vehicular power train systems with continuously variable transmission (CVT). The modeling includes an analysis of the systems' components which include the spark-ignition internal combustion engine, the torque converter, the continuously variable transmission and the wheels. The CVT offers...
In view of the current widely used city intersection signal control system, oriented by the concept of automatic sensor signal control, this paper tries to use a computer's procedural method, with the input of initial conditions, after automatic calculation, a result which will make the vehicles go through the intersection causing the shortest signal control delay time totally will be generated automatically,...
With the CAN/LIN network using in the Automobile Body Control System widely, in order to economically achieve the reliable communication in the vehicle, this article has designed a communication gateway based on ARM968E-S.This scheme introduces characteristics of ARM controller (LPC2919/01) and the CAN receiver (CTM1050T) in particular, achieved the software and hardware design of the CAN/LIN gateway...
Statistical data shows that a driver who was lack of the ability to discover potential risk situation and safe driving awareness was more probably to cause an accident. The safe driving awareness was considered as a factor in contributing to vehicle crashes. In this study, a creative method to improve safety awareness based on driving simulator was proposed. Firstly, the definition and classification...
Electrical storage devices can be very useful in electrified mass transit and in particular in trolleybus lines and tramways. In fact, storage devices are capable of supporting the line voltages of old lines, avoiding the opening of minimum voltage protective relays, especially when the new generation vehicles of greater power circulate. Among electrical storage devices, supercapacitors seem to be...
Under the emergency accidents, implementation of the rescue measures is directly related to the traffic state identification. However, lacking of information collecting caused by road damage would lead to the results of identification by conventional fixed detector had a larger deviation. Although the existing way of probe vehicle with a large coverage area but also from an environmental impact, the...
This paper investigates vehicle health monitoring system (VHMS) on electric wheel truck. VHMS is connected with the control system of the electric wheel truck. It has local real-time system clock, mass size nonvolatile memory, and several interfaces such as Universal Serial Bus (USB), RS-232 and Ethernet for data transmission and download communication. Using General Packet Radio Service (GPRS) module,...
The information of vehicle is very important for maintaining traffic order under the present complex traffic environments. The image of vehicle is captured in various ways; fixed camera, movable camera, and vehicle-loaded camera. This paper proposes a new vehicle plate recognition mechanism that is essential to know the information of vehicle. The proposed method is a real-time processing system using...
Focusing on the problem that the detection accuracy of traffic detection system is sensitive to the changes of complex environments, this paper presents an improved method of vehicle detection. It builds and updates the background adaptively. Additionally, to improve the computation efficiency of shadow elimination, a fast algorithm of neighbor mean based on HSV model is proposed. As the occlusion...
An improved monocular vision method is studied for intelligent vehicle to detect the preceding car in the structural road environment. Through identifying the edges of the car, the object is detected; the false object is eliminated and the eligible object expressed as a 2-D model is acquired. Then the location of object in the next frame is predicted by Kalman filter, and the object is detected near...
Red-light violation video detection is one of the critical techniques in the intelligent transportation system, it is superior to traditional detection methods in aspect of function and maintenance. According to the practice of crossroads and the characteristics of vehicles running red-light, this paper presents a vision vehicle detection algorithm based on detection region to detect moving vehicles,...
In this paper In this paper, which is one of the part of the development for the automation system in the navigation process, covers the car system. Local detection system based on pseudo-satellite was used to be able to detect the space coordinates and the absolute location with four ultrasonic transmitters and two receivers. Using this system we get the lateral dynamic model of a reduced car by...
Drivers have to change their sightline to focus on the vehicle's visual speedometer to check the speed at which they are travelling. This may be a dangerous loss of concentration. A head-up display was developed to solve this issue. HUD has several issues. Large amounts of visual information can create visual clutter and degrade the driver's information processing due to cognitive overload. The HUD...
There are a lot of cases with vehicle parking methods. But, when we try to analyze the successful parking patterns, we will be known that all processing is accomplished within specific parking pattern. We collect and analyze various parking patterns, so suggest the parking planning algorithm that do mission safe and effectively, when Unmanned Ground Vehicle (UGV) starts parking mission.
This paper would like to design the failsafe architecture to ensure the stability and safety of unmanned ground vehicle (UGV). Because the failure in the unmanned systems can cause a nasty accident. So, first, we limit the discussion to the UGV in the unmanned systems. And then we find out failure for the UGV which consists of the variety of the hardware, and discuss the danger. And we define the...
Present Traffic Light Controllers (TLC) are based on microcontroller and microprocessor. These TLC have limitations because it uses the pre-defined hardware, which is functioning according to the program that does not have the flexibility of modification on real time basis. Due to the fixed time intervals of green, orange and red signals the waiting time is more and car uses more fuel. To make traffic...
