Road networks are the most important facility to the public transportation in modern cities. Governments around the world allocate large amounts of budgets for the pavement maintenance every year. In this paper, we proposed a crowdsourcing solution to categorize road anomalies into safety related anomalies such as speed bumps and rumble strips, and dangerous anomalies such as bumps and potholes. The...
Path planning plays an important role in the area of mobile robot, which includes two important contents: environment modeling and path searching. The method of Voronoi diagram for general figures by approximation structuring is utilized and the origin and terminal are linked into diagram to construct the non-collision road map. Zonal Ant Colony Algorithm is applied to search the shortest path between...
Nowadays, many people depend on the guidance provided by car navigation devices to travel to the destination. Generally, several routes are possible for a given origin-destination (OD) in a road network. Often car navigation devices provide the minimum traveling time or distance route. However, this route may not always be comfortable for users to follow. Out of the several available routes, users...
The multiple origins multiple destinations routing (MOMDR) problem becomes extremely complicated when considering the traffic volumes on road sections. When solving this kind of problem, only heuristic algorithms have practical values because it is a typical NP-Hard problem. This paper applies Genetic Algorithm (GA) to enhance Sorting-Randomizing-Adjusting-Updating (SRAU) algorithm. The former paper...
