The Based on the analysis of the connotation about urban transportation sustainable development in Shandong Province and its present situation, this paper constructed appraisal index system about urban road transportation sustainable development ability and established fuzzy analytic hierarchy process model (FAHP) to make synthetic evaluation on it from five aspects such as urban road infrastructure...
The pedestrian violation crossing behavior (PVCB) of urban arterial road is the main object of the study. On the basis of measured data and qualitative analysis of PVCB influence factors (IF), the main factors are extracted by using factor analysis and the PVCB IF indexes system is established. Finally, adopting logistics regression model, a decision-making model of PVCB in crosswalk of signalized...
Facing to the uncertainty problem of dynamic transport network for the big cities, this paper begins from the viewpoint of connectivity reliability, analyses evaluation method for connectivity reliability, and put forward LOS-based connectivity reliability evaluation model (LOS-CRE model), that integrates traffic level-of-service into reliability evaluation, and that is reference to grades of level...
This paper studies roadway network capacity by applying a stress test method to estimate the ultimate limitation of the roadway network to accommodate the travel demand. The method considers the factors affecting capacity of roadway network and defines the evaluation index of roadway operation quality--the average degree of saturation of traffic flow and the average speed. By using macro traffic simulation...
There is no one standard take for granted in the world, therefore, in this paper, city road-network traffic congestion is divided into road section congestion and cross congestion, and is classified as five classes: congestion, crowd, general crowd, general unimpeded, unimpeded. The indexes for evaluation of city road network traffic congestion are selected, and the two hierarchy evaluation index...
The optimal route guidance, is an important part of ITS. The factors influencing route guidance, such as the position of vehicles, the information on road conditions, the free parking spaces, etc., are dynamically variable. These dynamically factors are constrained conditions. How to construct the optimal model of vehicle route guidance under such constrained conditions is a difficulty that puzzles...
