Embodiment Construction

[0022] The technical solutions of the present invention will be clearly and completely described below through specific embodiments in conjunction with the accompanying drawings.

[0023] A method for judging expressway congestion, comprising a street sign and a driving card. When the driving card is within the signal coverage of the street sign, the two communicate with each other periodically, and the driving card is placed in a vehicle. When the vehicle enters the expressway, the expressway staff will assign a driving card to the vehicle, and bind the vehicle information in the driving card; or, a vehicle information identification device is installed at the ramp position at the entrance of the expressway, and when the vehicle information After the identification device recognizes the vehicle information, the vehicle information is automatically uploaded to the travel card, and then the staff distributes the travel card recorded with the vehicle information to the driver. T...

Abstract

The invention provides a highway congestion judgment method. The highway congestion judgment method comprises the following steps: periodically sending inquiry data by a guide board; when the guide board receives the response data sent by the driving card for the first time, recording the identity information of the driving card, and starting the timing; determining whether the response data is received in each period or not by the guide board; if yes, continuously and periodically determining whether the response data is received or not in each period; if not, determining whether the number of the periods without receiving the response data is greater than a preset value or not; and if not, continuously and periodically determining whether the response data is received or not in each period; and if yes, stopping the timing; determining whether the timing duration is larger than the preset duration by the guide board, if not, indicating that the road is smooth; if yes, indicating the road congestion; and releasing the storage space. According to the highway congestion judgment method, the highway congestion judgment can be achieved without monitoring equipment and the transformation of a highway.

Description

technical field [0001] The invention relates to the field of expressway road condition monitoring, in particular to a method for judging expressway congestion. Background technique [0002] With its unique advantages of being closed, high-speed and fast, the expressway greatly facilitates people's work and life. However, due to the extremely long distance of the expressway, it is impossible to monitor the road conditions on all roads in real time. When the expressway is congested, the expressway The management center is often unable to obtain the road condition information at the first time, and if more vehicles flood into this section of the expressway, the congestion will be aggravated; damage. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention provides a method for judging highway congestion. By issuing a driving card to each vehicle and transforming the highway signs, the road congestion judgment can be rea...
