Problems solved by technology

[0003] However, the above-mentioned management scheme for traffic conditions is mainly to identify and guide the congestion that has already occurred, but cannot effectively prevent it.
In addition, most of the existing traffic control methods in related technologies only consider the traffic status of local road sections, resulting in congestion that may only be transferred from a certain local road section to other local road sections, and cannot completely solve the problem of larger-scale traffic congestion.

example 1

[0085] Example 1. Traffic optimization control method for local continuous road sections:

[0086] The first method corresponding to the local continuous section includes:

[0087] In the case where the traffic parameters of the local continuous road section meet the preset conditions, the upstream control road section speed limit value and the current limiting strategy that maximize the total traffic flow of the local continuous road section within the first time length are calculated;

[0088] Wherein, the preset conditions include at least one of the following:

[0089] The average speed is lower than a first standard threshold, the traffic density is greater than a second standard threshold, the speed variance is greater than a third standard threshold or the vehicle position variance is greater than a fourth standard threshold.

[0090] A roadside device is erected every 0.5-1km along the road extension, and the sensing range of the roadside device is the road section co...

[0102] Example 2. Traffic optimization control method for local bottleneck sections:

[0103] The local bottleneck road section includes a control road section and a bottleneck road section; the control road section is an adjacent upstream road section of the bottleneck road section, and its traffic capacity is greater than that of the bottleneck road section. For example, the local bottleneck section can be as follows Figure 6 As shown, wherein, road section 1 can be a control road section, road section 2 can be a bottleneck road section, the number of lanes of road section 2 is less than road section 1, that is, the traffic capacity of road section 1 is greater than that of road section 2.

[0104] The second method corresponding to the local bottleneck section includes:

[0105] The roadside equipment obtains the traffic parameters of the bottleneck section and its upstream control section;

[0106] When the traffic parameter represents that the traffic flow of the upstr...

[0125] Example 4. Optimal control method for a single outlet diversion area:

[0126] For single outlet diversion area, see Figure 9 In the schematic diagram of the scene shown, road section 1 is an upstream road section, road section 2 is a diversion area, road section 3 is an exit ramp, and road section 4 is a downstream road section.

[0127] Correspondingly, the fourth method corresponding to the single outlet diversion area includes:

[0128] The roadside equipment obtains the traffic parameters of the diversion area, and determines the exit flow ratio based on the traffic parameters;

[0129] Calculate the speed and entrance traffic flow of the upstream section that can maximize the sum of the diversion area, the upstream control section and the input traffic flow.

[0130] Wherein, the calculation can make the diversion area, the upstream control road section and the input traffic flow and the maximum speed of the upstream road section and the entrance traffic flow c...

Abstract

The present application discloses a traffic control method, management platform, roadside equipment and system, wherein the method includes: the management platform acquires traffic parameters, local strategies and Full-line traffic demand information; the management platform formulates constraints based on the full-line traffic demand information, traffic parameters of at least one secondary road section in the at least one first-level road section, and local strategies, and determines the control range according to the constraints The ingress distribution traffic within the first time length corresponding to each first-level road section within the control range; the management platform sends the entrance distribution traffic within the first time length of each first-level road section within the control range to each first-level road section The roadside equipment at the entrance is used for traffic control of signal lights or toll stations.

Description

technical field [0001] The present application relates to the field of intelligent transportation, in particular to a traffic control method, management platform, roadside equipment and system. Background technique [0002] In related technologies, the management of traffic conditions is mainly to identify congestion or abnormal phenomena, take corresponding measures to prevent the congestion from spreading, and solve the congestion phenomenon as soon as possible. [0003] However, the above-mentioned management scheme for traffic conditions is mainly aimed at identifying and unblocking existing congestion, but cannot effectively prevent it. In addition, most of the existing traffic control methods in related technologies only consider the traffic status of local road sections, resulting in congestion that may only be transferred from a certain local road section to other local road sections, and cannot completely solve the problem of larger-scale traffic congestion.
