A simplified method for off-line track matching for fleet managements

Abstract

This paper presents a method to measure the discipline in fleet management automation. This method is based on calculating the matching degree between the actual track and the desired track. The actual track is a sequence of points that is provided by the Global Positioning System (GPS) and the desired track is also a sequence of points that is provided by the Geographic Information System (GIS). This algorithm simplifies the tracks into straight segments, then determines the matched and unmatched segments. The points where the vehicle left and return to the desired track are determined, and the difference in distance between these points is determined too. The significance of this method comes from its simplicity and speed.

Influence of battery capacity on performance of an electric vehicle fleet

“…The VRP, first defined by Dantzig e Ramser in 1959 [5] is a more general form of the traveling salesman problem adjusting for customers' demands and vehicles' capacities [6]. Another group of studies in the literature is focused on the applications of global positioning system (GPS) or global systems for mobile communication (GSM) in monitoring and management of a fleet of vehicles [7]- [9]. In this study, it is assumed that these technologies are available in EVs and they can find the best route to a target point using these devices.…”
