Problems solved by technology

However, in practice the problem may arise that if the number or density of probe vehicles in an area of ​​the road network is low, there may not be enough information available to reliably determine traffic conditions

Embodiment Construction

[0017] An overview of the basic method of the invention follows.

[0018] Traffic conditions are monitored along an off-call path using off-call tracking of a cellular mobile communication device carried in a vehicle. When the monitored traffic conditions indicate that there is congestion on the off-call path, analyzing traffic data obtained from GPS-equipped probe vehicles on roads corresponding to the congested off-call path to more precisely determine the location of the congestion and severity. Once the precise location and severity of congestion is determined, subsequent changes in congestion can be monitored using disconnected call tracking.

[0019] The present invention fuses traffic information obtained by disconnect call tracking and GPS rovers to provide better traffic than disconnect call monitoring alone can provide, even in areas of the road network where there are not enough GPS equipped rovers. More detailed information about congestion to reliably provide a ...

Abstract

A method of identifying congestion comprising the steps of monitoring traffic conditions using off call tracking data relating to cellular mobile communication devices carried in vehicles along an off call path and determining when an off call path crossing time of the call path exceeds a threshold. When the off call path crossing time exceeds the threshold, obtaining traffic data from probe vehicles on roads corresponding to the off call path, and analysing the traffic data to determine the location of the congestion along the off call path.

Description

technical field [0001] The present invention relates to the collection of traffic data by means of mobile communication devices, and in particular to the collection of traffic data identifying congestion. Background technique [0002] Traffic and travel information is important in calculating journey times and avoiding congestion that delays individual route completion. There are many ways to obtain traffic information and calculate travel time. [0003] In its simplest form, arithmetic by dividing the distance to be traveled (estimated or obtained from a map) by the average travel speed (estimated or in the case of heavy goods vehicles obtained from analyzing dashcam data) Calculate travel time accurately. Journey times and ETAs are not particularly accurate, and don't really take into account long-term (e.g. roadwork) or short-term (e.g. traffic accidents) potential traffic congestion. [0004] Business operations require greater accuracy in predicting travel times, esp...
