Intersection real-time intelligent safety warning system based on intelligent phones and cloud computing and implementation method thereof

Abstract

The invention relates to the technical field of traffic safety, in particular to an intersection real-time intelligent safety warning system based on intelligent phones and cloud computing and an implementation method of the intersection real-time intelligent safety warning system. The existing GPS navigation technology and precision are utilized, and the intersection real-time safety warning is achieved based on the hardware technology of the intelligent phones and the cloud computing software technology. The intelligent phones of drivers / passersby are utilized, the longitude and latitude of the position are determined, running / walking speed is calculated, the longitude and latitude of the position and the running / walking speed are uploaded to a server of the system through a cloud platform, the server computes the distance between the running vehicles / walking passersby and intersections based on the intersections, computation is carried out, the probability that traffic conflict happens to the running vehicles / walking passersby is judged, and if the traffic conflict possibly happens to the running vehicles / walking passersby, warning messages are sent to the intelligent phones of the drivers / passersby in real time, and the intelligent phones send out the warning through vibration / sounds / voices after receiving the messages. Only a small client side program provided by the system needs to be downloaded and installed, special hardware equipment is not needed by a user, and implementation and popularization are easy. All the varieties of the traffic conflict can be avoided.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to the technical field of traffic conflicts. Background technique [0002] Since Professor Yang Xiaoguang, an internationally renowned scholar, proposed Intelligent Transportation System (ITS for short) in 1996, this field has developed rapidly in traffic engineering, and many innovations and ideas have been applied in real traffic. In traffic engineering, traffic safety and traffic conflict is an important research content. To reduce traffic conflict is to increase traffic safety. At the International Traffic Conflict Academic Conference in 1977, Amundsen Hyden proposed the basic definition of traffic conflict, that is, two or more road users are close to each other to a certain extent in a certain time and space. There is a danger of a collision, a phenomenon known as a traffic conflict. Traffic conflict technique is referred to as TCT (Traffic Conflict Technique), which...
