Transit oriented transportation development strategy has been widely used, its basic idea is the mechanism of the interaction between land use and bus system. However, there is only a few quantitative studies over this mechanism. Herein through the research of traffic demand generation process, we have studied the interaction mechanism between land use and bus system, and then established a mathematical...
Surveillance camera, as an important component of intelligent transportation system, has had a big development in China. The study adopted the algorithm of graphic minimal covering to figure out economical and reasonable locations for surveillance cameras distribution in small and medium-sized city road networks. The minimal covering algorithm was further applied in a case study of an urban industrial...
It is well known that limited safety distance and excessive intersections are the main reasons of the increasing traffic accidents on arterial roads. Based on the highway functional classification and intersection control types, the intersection spacing mode is divided firstly to make sure the arterial road access spacing and intersection corner clearance as the research object. Then for the concept...
Death and injuries as a result of road accidents is a recognized global problem and authorities are aware of the consequences this global phenomenon might lead to. Roadway safety is one of the most important issues in transportation. Intersections are the locations with higher traffic crashes as compared with other roadway locations. This paper introduces an approach to evaluate roadway intersection...
The unique characteristics of highway intersections have caused them to be the most dangerous places in the road system. Complexity of causes of traffic crashes at highway intersections, difficulty in data collection of traffic accidents and traffic conflicts and many other reasons have made safety performance evaluation of highway intersections one of the most difficult tasks, in spite of the fact...
Network design problem has originated in the practice of traffic engineering. Planning and designing road system has always been the most important task of traffic engineers. The objective of network design problem is to plan and design an improvement project for a road network systematically so that the total travel cost of the whole road system is minimized. Because of the complexity of the models,...
We demonstrate MetroNet, which is an application that illustrates collaborative data sharing on the Wide Wide Web. MetroNet has two parts. First, our sensors gather data about pedestrian foot traffic in front of and into stores, which is made available online to shopkeepers. Second, this sensor data can be made public, at the discretion of the shopkeeper, for use by city planners, other shopkeepers,...
