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...
In order to eliminate accident, reduce congestion and improve the efficiency of the traffic circle, three effective and feasible methods are proposed.As an example,the traffic circle flow of the circle in Xiamen China is simulated by these methods above using VISSIM soft.The results of simulation show that three methods applied to different traffic flow each,then we did further simulations to the...
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,...
Former research of transport reliability focuses on road network, few of which refer to the intersection traffic reliability in microcosmic level. The paper proposes the conception of traffic reliability based on which the supply-demand reciprocity is analyzed, and brings forward the methodology that the disabled condition should be differentiated according to distinct system functions. Aiming at...
Firstly the necessity of the design of signal coordination control system in urban main roads is presented , and the design thinking and process of the signal coordination control system is given, then according to the design thinking and process create a model of signal coordination control system in urban main road., and Qingyang Road of LAN Zhou City is taken for example, based on the survey data...
The vehicle control system based on Network communication becomes increasingly complicated recently. The traditional research only focuses on the improvement of network communication quality or system control performance. The network configuration had been carried out to study the vehicle chassis integrated control system. Based on the MATLAB/Simulink and TrueTime Toolbox, the distributed CAN network...
Recent research studies on green cellular networking indicate that most of the traffic is serviced by a few cell sites while the rest of the cells remain under-utilized, contributing to significant energy consumption levels. Previous proposals suggest turning off Base Stations (BSs) during low utilization periods to save energy by allowing neighboring cells to increase their coverage to provide 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...
Intelligent Transportation Systems are based on the acquisition of urban traffic information timely and accurately. This paper puts forward a prototype system of Wireless Traffic Information Service System(WTISS). In WTISS, vehicles equipped with wireless communication module are regarded as moving sensors on traffic network. Road-side station can get traffic status by analyzing data collected by...
Passenger information systems about bus arrival at bus stops, which is an integral part of any advanced public transportation systems (APTS) application, is catching the attention of traffic engineers in India in recent years. APTS, by making the public transport system more attractive, will encourage people shift from personal mode to public mode for their transport, thus relieving congestion. There...
VANET is an ad hoc network composed of highly mobile vehicle nodes. Many routing protocols utilize traffic information as a critical metric for determining optimal message forwarding path. The existing traffic information systems are not suitable for routing decision either because of the huge development and maintenance cost or due to the insufficient information provision. In this paper, a new distributed...
