Problems solved by technology

In the city where the car owner lives, the car owner pays more attention to the traffic conditions of the road, but the current car navigation equipment cannot provide real-time information on the latest traffic conditions in the city
As far as navigation itself is concerned, navigation can only be based on static parameters such as the shortest route, and cannot be combined with the latest traffic conditions in the city to bypass congested roads

Embodiment Construction

[0057] Embodiments of the present invention have been clearly illustrated during the description of the solutions of the present invention.

[0058] In the present invention, the selection of the vehicle-mounted Bluetooth device and the establishment of the Bluetooth base station indicate that the positioning and GPS speed measurement sequence values ​​obtained from the vehicle-mounted navigation device are exchanged through Bluetooth. This approach is based on existing equipment conditions.

[0059] If along with the progress of Internet technology or the change of network environment, the vehicle-mounted navigation equipment can directly carry out Internet communication, then the information exchange based on Bluetooth of the present invention just can use direct Internet communication instead. Therefore, it is not essential to use Internet communication, Bluetooth communication or other wireless communication to achieve the purpose of communication and information exchange....

Abstract

The invention provides a method for directly acquiring the traffic speed of an urban road, which can be used for directly acquiring the real-time vehicle running speed of each urban street so as to reflect the urban traffic situation in real time. The invention overcomes the defect that plentiful fuzzy measuring values need to be used in the existing urban transport traffic management, and specific digitized speed values can be used for replacing the fuzzy statements such as 'unblocked roads' or 'slow traffic' and the like. The invention provides a foundation for realizing urban traffic automation; by the real-time release of a server to the outside, vehicle-mounted navigation equipment can acquire the latest road traffic condition information so as to realize the optimized navigation; and by the invention, urban traffic intelligent improvement can be further carried out, and traffic lights at intersections can be automatically controlled, thereby realizing automatic traffic diversion.

Description

technical field [0001] The invention relates to urban road traffic management technology. Background technique [0002] With the rapid increase of urban car ownership, the problem of urban road traffic is becoming more and more serious. [0003] At present, urban road traffic is mainly controlled through flow from a technical perspective. For example, install ground sensing devices on certain road sections to obtain traffic flow by counting, or install cameras to obtain traffic flow through video image analysis. [0004] In fact, it is incorrect to control urban road traffic through traffic flow. There is no necessary connection between the traffic flow statistics and the smooth flow of urban roads. The traffic flow is heavy and the traffic is slow. Although these two irrelevant meanings are often talked together, it is logically untenable to conclude that the reason for the slow traffic is the large traffic flow. Large traffic flow refers to the large number of vehicles...
