Embodiment Construction

[0018] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0019] Such as figure 1 As shown, the city variable information sign ground traffic guidance road section determination method of the present invention comprises the following steps:

[0020] Step S-1: After obtaining the urban road traffic data within a certain statistical period, carry out the judgment of frequent congestion on urban ground roads

[0021] The identification of frequent congestion on urban surface roads includes the identification index of traffic congestion index and the statistics of frequent congestion sections on urban surface roads.

[0022] Step S-1-1: Identification of Traffic Congestion Index

[0023] The traffic congestion index of urban roads is a standardized index that fairly reflects the relative congestion experience of road vehicles of all levels. The core calculation parameter is the road travel...

Abstract

The present invention relates to a determining method for the traffic guidance road segment of an urban variable information-identified ground. According to the technical scheme of the determining method for the traffic guidance road segment of the urban variable information-identified ground, the phenomena of unreasonable variable information-identified guidance road segments, resource waste, public dissatisfaction and the like can be avoided. In combination with urban ground road recurrent congestion discrimination indexes, road grade discrimination indexes and variable information-identified road guidance forms, variable information-identified guidance road segments are more scientific and more reasonable.

Description

technical field [0001] The invention relates to a method for determining a ground traffic guidance section of an urban variable information sign, which belongs to the field of urban traffic guidance systems. Background technique [0002] With the development of society and economy, the number of motor vehicles has increased rapidly, and the situation of traffic congestion and traffic disorder in large and medium-sized cities has become increasingly serious. Variable information signs provide road users with traffic status information on the road ahead, so that drivers can keep abreast of various traffic conditions while the vehicle is moving, can divert traffic in time, reduce congestion, and facilitate traffic flow, thereby improving the overall urban traffic system. Use efficiency of resources, reduce resource consumption and reduce environmental pollution. [0003] At present, the guidance road section in the off-site variable information sign is determined extensively, ...
