Roads' overload remains a major challenge although they are constantly expanded in order to increase their capacity and improve their efficiency. This tends to cause many problems: environmentally, economically and socially. The advancement of urban traffic management systems, construction and expansion of roads are solutions to address this problem and improve the performance of the road circulation,...
This paper is concerned with how to accurately position and find an optimal path through Vehicle Navigation System. This article designed a vehicle dynamic navigation system based on Internet of Things, by using the improved Ant Colony Algorithm. Through computer simulation, we obtained two simulation figures of static navigation route and dynamic navigation route. Besides, the driving directions...
This paper presents an integrated framework of Geographic Information System (GIS) and a Relational Database Management System (RDBMS) equipped with interactive communication capabilities. The model integrates the design of the database and the management of implementation of the monitoring system which includes the operations of query and analysis using the web and desktop applications. This study...
Nowadays, to avoid over-speed and parking violation, repair vehicles are commonly monitored and positioned under monitoring and dispatching system by most of local-level power supply enterprises. With the development of electric utilities, power supply enterprises are urged to improve their response speed to power troubles. In such a situation, electrical repair vehicles must be under a status of...
The dynamic road traffic management is based on the dynamic vehicle routing during peak hour traffic. The real time traffic management has become a hectic problem in daily life due to the increasing traffic, sudden accidents, and bottle necks due to various reasons. In Dynamic Vehicle Navigation System (DVNS), the real time traffic junctions are mapped as nodes and the traffic rate between the signals...
In order to improve the efficiency of road network route planning,many experts and scholars have conducted some studies, Dijkstra's algorithm is a research hotspot. The Dijkstra's algorithm has its own shortcomings when seeking an optimal path between two points, but it has irreplaceable advantages. Through the analysis of strengths and weaknesses of the classic Dijkstra's algorithm, we can find that...
The path length and number of turns are the major factors in path planning of transportation and navigation systems. Shortest path planning has been widely studied in the literatures. Most researches only take the issue of shortest distance into account, and the impact of turns are rarely mentioned, that is, the shortest path may not be the fastest. Considering both two factors in a path-searching...
