A road condition information prompt system for temporarily closed sections of urban roads

Abstract

The invention relates to a road condition information prompting system for temporarily closed sections of urban roads, which is used in the technical field of traffic. It includes a signal collection device arranged in a temporarily closed road section, a signal collection system arranged in the signal collection device, a helical antenna and a path planning system arranged in the vehicle. The central processing unit of the present invention can determine the road condition information of the closed road section according to the mutual communication between the signal acquisition devices; the helical antenna can transmit the surrounding road information to the surrounding vehicles, and notify the surrounding vehicles in advance of the information of the closed road section in front, and the path planning system is mainly based on the local area. The detour plan is calculated from the map information and temporarily closed road section information, and the driver can independently choose the detour plan provided in the route planning system; it provides great convenience for the driver, and also greatly reduces the occurrence of accidents; Great marketing prospects.

Description

technical field [0001] The invention belongs to the technical field of traffic, and in particular relates to a road condition information prompting system for temporarily closed sections of urban roads. Background technique [0002] Entering the 21st century, with the rapid development of urban social economy, the demand for urban transportation has increased rapidly, and the current urban transportation infrastructure has not adapted to the needs of urban population growth. At the same time, with the rapid increase in the number of motor vehicles, traffic congestion in large and medium-sized cities is serious, and the speed of traffic arteries continues to decrease, which forces the urban traffic planning department to continuously plan new roads and widen original road sections. The closed construction of the road section, if the traveler drives the vehicle near the closed road section, he finds that the front road section is closed for construction, and re-adjusts the dir...

Problems solved by technology

At the same time, with the rapid increase in the number of motor vehicles, traffic congestion in large and medium-sized cities is serious, and the speed of traffic arteries continues to decrease, which forces the urban traffic planning department to continuously plan new roads and widen original road sections. The closed construction of the road section, if the traveler drives the vehicle near the closed road section, he finds that the front road section is closed for construction, and re-adjusts the direction of driving, which often causes a lot of waste of time and energy, and in many cases causes traffic congestion (according to common sense experience, in many cases closed The conditions of the road sections near the construction section are very poor. In many cases, it is a one-way street or the road ahead is blocked, which can easily cause vehicles to enter a dead end.)

[0003] At present, many temporarily closed road sections do not have effective reminder systems and devices. Generally, drivers plan to detour around the closed road section ahead based on the information obtained from the driver's last pass through the road section. For some drivers who drive to the temporarily closed road section for the first time, In most cases, it is found that the road ahead is closed for construction when driving near the closed road section, and the driving direction is temporarily adjusted, resulting in a lot of waste of manpower and material resources
