Embodiment Construction

[0060] The implementation example of the present disclosure proposes a two-way report technology of at least one detective vehicle and a dynamic traffic service management center. Thus, the dynamic traffic service management center periodically broadcasts the real-time maximum speed of each road section through the wireless network, and the faster speed detective car first returns the real-time speed to the dynamic traffic service management center, and then the dynamic traffic service management center broadcasts ( broadcast) to report the fastest vehicle speed. Other detective cars with slower vehicle speeds no longer report the vehicle speed, so as to reduce the number of information reports from the detective vehicles and reduce the load of the dynamic traffic service management center.

[0061] Figure 4A It is a schematic diagram of an example of a traffic notification system that reduces communication requirements, which is consistent with some disclosed implementation...

Abstract

The invention relates to a traffic notification system for reducing a communication demand and a method thereof. According to an embodiment of the traffic notification system for reducing a communication demand, each probe vehicle of at least one speed probe vehicle device like a probe vehicle is communicatively coupled to a dynamic traffic service management center; the dynamic traffic service management center periodically broadcasts a high speed in a period collected during the last period as well as irregularly broadcasts an instant high speed which is reported back in a current period; after at least one probe vehicle receives the speed broadcasted by the dynamic traffic service management center, a corresponding instant high speed in the current period is selectively reported to the dynamic traffic service management center.

Description

technical field [0001] The present disclosure relates to a traffic notification system and method that reduces communication requirements. Background technique [0002] Real-time traffic information, such as road conditions, vehicle speed, traffic flow and other information, is an important part of the intelligent transportation system. It can provide passers-by with real-time traffic information to save driving time and energy consumption. Based on such information, value-added service providers can provide services such as vehicle navigation, fleet dispatch, and traffic control. The basis of such traffic information services lies in the collection of real-time traffic information (such as road traffic volume and speed). Real-time traffic information collection methods include setting up fixed vehicle detectors, using wireless telecommunication networks to track the location of users' mobile phones, and equipped with Global Positioning System (GPS) probe vehicles to report...
