Embodiment Construction
[0036] The present invention will be further described below in conjunction with the accompanying drawings.
[0037] refer to Figure 1 ~ Figure 3 , an automatic induction method based on road flow detection, including the following steps:
[0038] Step 1: Set the shunt threshold. When the average lane flow of a road section reaches this threshold, it means that the road section is congested, and it is necessary to consider shunting traffic to adjacent road sections;
[0039] Step 2: Set the diversion ratio value. When the ratio of the average lane flow of the adjacent road section to the average lane flow of this road section is less than the diversion ratio value, it means that the adjacent road section is relatively smooth, and the vehicles on this road section can be flown to the adjacent road section. shunt;
[0040] Step 3: Establish a road number table (including at least road name, road ID and road number), in which the road name and road ID are the basic information...

An automatic inducing method based on road flow detection includes the following steps of firstly, setting a flow division threshold value and a flow division ratio value; secondly, scanning each road section in a city according to a scanning sequence, stating a next round of scanning after one round of traversal scanning is completed, and when a certain road section is scanned, conducting following judgment and corresponding operation, namely, calculating the lane average flow L of the road section, the left lane average flow L of a left adjacent road section and the right lane average flow L of a right adjacent road section, issuing inducing information at a starting crossing of the road section and guiding vehicles to flow to the adjacent road sections when the L of the road section reaches the flow division threshold value and the ratio of the lane average flow of each adjacent road section to the lane average flow of the road section is smaller than the flow division ratio value, and stopping issuing corresponding inducing information when the inducing information has been issued and the lane average flow of the road section is smaller than the lane average flow of each adjacent road section. The invention further provides an automatic inducing system. The automatic inducing method and system are good in accuracy, good in instantaneity and high in urban road use ratio.
Description
technical field [0001] The invention relates to the field of intelligent transportation, in particular to an automatic guidance method and system. Background technique [0002] With the continuous development of urbanization in our country, the population and the number of motor vehicles in large and medium-sized cities have increased rapidly. However, due to the constraints of factors such as region, space, capital investment and road construction cycle, the speed of urban road construction is relatively slow, and road congestion is common. . In areas with traffic congestion, it is often necessary to send a large number of police forces to clear the traffic, and the time to clear it is usually relatively long, which consumes a lot of manpower and material resources. [0003] In order to solve the road congestion phenomenon, an effective solution is to divert vehicles on congested road sections through the guidance system in the early stage of congestion, and guide vehicles...
