Real-time traffic early warning management and control method and system for mountainous city hot spot area

Abstract

The invention discloses a real-time traffic early warning management and control method for a mountainous city hot spot area. The method comprises the steps of 1, obtaining traffic data of a mountainous city; 2, determining the number of vehicles in the network and a congestion delay index in a time period according to the data; 3, carrying out early warning according to the number of vehicles inthe network and the congestion delay index in the time period; 4, according to the early warning level, inputting the congestion delay index into a relation model of the congestion delay index and thenumber of vehicles in the network at a moment; and 5, determining actual control flow according to an output result of the relation model. According to the real-time traffic early warning managementand control method, stable and controllable flow of a key area and flow balance of an associated road network are ensured, traffic operation pressure of a mountainous city hot spot area and a surrounding road network is relieved, early warning processing can be carried out, and the management and control efficiency can be improved.

Description

technical field [0001] The present invention relates to the field of traffic management and control, in particular to a method and system for real-time traffic early warning management and control in hotspot areas of mountainous cities. Background technique [0002] The spatial form of mountainous cities presents a "multi-center" and "multi-cluster" pattern, with heavy traffic flow and significant road bottlenecks, which makes it more difficult to control hotspot areas and invisibly increases social and economic losses and environmental pollution. In the field of road traffic control, most of the control methods rely on previous traffic control experience and adopt a "one-size-fits-all" control method. Although the pressure on road traffic operations in hotspot areas is relieved to a certain extent, the lack of traffic data support and scientific control methods has led to surrounding areas being trafficked. The traffic situation of the strictly controlled related roads has ...
