A tidal lane recognition method and system

Abstract

The invention provides a tide lane identification method, comprising steps of obtaining IDs of all intersections through reading an intersection table, marking all the IDs of the intersections as Unvisited, marking one of the ID which is marked as unvisited as visited, taking the intersection ID as a lower stream intersection ID or an upper stream intersection ID gauge checking road segment table to obtain the road segment ID connected to the intersection ID, performing road segment matching, if the upper stream intersection ID of the two road segment IDs corresponds to the lower stream intersection ID and the lower stream intersection ID corresponds to the upper stream intersection ID, matching the road segment successfully and proceeding to the next step of processing, if the matching is not successful, not proceeding the ID of the road segment to the next processing, for the road segment ID pairs which are successfully matched, performing the statistic on the number of the lanes of each road segment according to the road segment ID vehicle checking lane table MD_LANE, and performing summation on the ID pairs of the same road segment. If the total lane quantity meets the &1t;3, the ID of the road segments does not meet the lane condition, and the processing is not performed; and if the total lane quantity meets >=3, the determination on the direction of the light traffic flow and the heavy traffic flow based on the morning peak and the evening peak, the direction of the heavy traffic flow, flow statistic, calculation direction coefficient and traffic capacity is performed to realize the recognition of the tide lane.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a tidal lane identification method and a computer system. Background technique [0002] The difference in the nature of urban land use leads to uneven distribution of traffic attractions in time and space, and the phenomenon of tidal traffic in morning and evening peaks is obvious, so road resources cannot be allocated and utilized to the maximum extent. In the morning rush hour, most of the trips are from the place of residence to the place of work, while in the evening rush hour, most of the trips are from the place of work to the place of residence, resulting in a serious imbalance in the direction of traffic distribution, resulting in tidal traffic phenomenon. The existing traffic planning and design can only meet the traffic demand during the off-peak period, but under the tidal traffic formed by the morning and evening peak hours, road resources are insu...

Problems solved by technology

[0002] The difference in the nature of urban land use leads to uneven distribution of traffic attraction points in time and space, and the phenomenon of tidal traffic in morning and evening peaks is obvious, so road resources cannot be rationally allocated and utilized to the maximum extent.

In the morning rush hour, most of the trips are from the place of residence to the place of work, while in the evening rush hour, most of the trips are from the place of work to the place of residence, resulting in a serious imbalance in the direction of traffic distribution, resulting in tidal traffic phenomenon

The existing traffic planning and design can only meet the traffic demand during the off-peak period, but under the tidal traffic formed by the morning and evening peak hours, road resources are insufficient or the lane distribution is unreasonable, resulting in heavy traffic delays and serious congestion. The road resources in the direction of light traffic have a problem of low utilization
