Speeding detection is a well-known technique that is widely adopted all over the world for traffic regulation. Current speeding detection methods can successfully measure the speed of vehicles at a single spot or the average speed of vehicles passing through a specific road section. However, based on these methods, if a traffic management agency wants to realize a full coverage of speeding detection on a road network, lots of equipments are necessary which will be very costly. This disclosure discloses a more cost-effective method based on data analytics.

Method and Apparatus for Realizing a Full Coverage of Speeding Detection on Road Networks with Limited Number of Speed Cameras and Public Traffic Data

Speeding on road network is a very common violation of traffic rules and it is one of the major factors that lead to traffic accident. Setting speed limit and punishing speeding driving behavior is an effective way of restricting speeding violations which is also widely adopted all over the world. To enforce speed limit, detecting speeding is very important. However, current solutions such as using single-point or point-to-point speed cameras have some major drawbacks. As the name suggest, a single-point camera can only detect speeding at the point where the camera is set. Drivers can successfully escape by slowing down their cars when approaching a single-point speed camera and speeding up after passing it. This trick no longer works when traversing a road section equipped with point-to-point speed cameras since this type of cameras can help calculate the average speed of a vehicle on the specific road section. However, the current point-to-point cameras are only workable on road sections without any exit or entrance. It would be very costly to realize coverage on the entire road network using current solutions. Due to these drawbacks, only speeding at certain points or in certain road sections can be detected. In other words, the coverage of speeding detecting is very limited. This disclosure discloses a method and apparatus that expand the coverage of speeding detecting to large regional road network with existing speeding detecting equipment (e.g., speed cameras) by leveraging public traffic data that is available to traffic management agencies.

This disclosure utlizes the data obtained from existing speeding detecting cameras and traffic sensors. An analytical method incorporating fastest-path/shortest-path algorithm, stochastic analysis and mathematical programming is used to identify suspected speeding behaviors. Traffic camera records will then be used to prove/disprove speeding. The main idea can be illustrated by the following figure.

Specifically, noting that any two consecutive camera record with time and vehicle identification can provide information to identify speeding, this disclosed method starts with recognizing the origin-destination (OD) pair of a target vehicle during a target travel using camera record. (A target vehicle can be randomly selected or it can be any vehicle that enters the zone under speeding monitoring if the traffic management agency has the ability to conduct big data analytics. The origin and destination of the target tra...
