Additionally, the same method is applied to the problem of vehicle tracking. Algorithm 1 Saliency map building 1: Initialize data structures 2: while scanning using image registration or feature matching techniques is infeasible because of

the spatial but also the temporal data of this system is the quality of Map- Matching This vehicle tracking on a given road segment is known as Map- Matching.

Literature uses the term ‘map matching’ for the problem of matching a sequence of (potentially inaccurate) vehicle position measurements to road segments of a street network [19]. In the scope of this paper, we refer to this problem as vehicle map matching. Position is typically measured with GPS tracking and live map can help by providing an overview of your fleet at a glance so you can always stay in control. Device Status Monitoring We provide device status monitoring so you would always be informed in case anything goes wrong and a device loses signal or stops transmitting data. Map matching is the problem of how to match recorded geographic coordinates to a logical model of the real world, typically using some form of Geographic Information System. The most common approach is to take recorded, serial location points (e.g.

from GPS ) and relate them to edges in an existing street graph (network), usually in a sorted list representing the travel of a user or vehicle. It may cause the tracking system unavailable. In order to improve the positioning accuracy of vehicle tracking system, a current statistical model is employed as the vehicle moving model. At the same time, the map-matching algorithm with the nearest location and the suitable moving angle is proposed to amend GPS measured data.

The objective of this work is to develop map-matching algorithms for vehicle tracking data that are used as a sensor data source to assess and predict the traﬃc condition in related applications. This section overall describes the properties of the tracking data with a focus on its accuracy to deﬁne requirements for map-matching algorithms. Vehicle tracking data is an essential "raw" material for a broad range of applications such as traffic management and control, routing, and navigation.

Vehicle tracking data is an essential "raw" material for a broad range of applications such as traffic management and control, routing, and navigation. An important issue with this data is its accuracy. The method of sampling vehicular movement using GPS is affected by two error sources and consequently produces inaccurate trajectory data.

This effort addresses the challenges of evolving map data sets, specifically by focusing on (i) automatic map-attribute generation (weights), (ii) automatic road network generation, and (iii) by providing a quality assessment. Positioning System (GPS) points is named map-matching. Map-matching algorithms aim to match points generated by GPS to a road network in order to determine a more accurate location of the GPS signal receiver. Di erent uses of the GPS require di er-ent performance speci cations of the map-matching algorithm.
