Embodiment Construction

[0046] The invention mainly combines the traffic characteristics of the port area, designs based on the ACT-R cognitive model, describes the driver's driving behavior, and then determines the main factors of the curve design in the port area through simulation.

[0047] The complete steps are as follows:

[0048] 1. Estimate the radius range of the curve circle curve according to the design speed of the road in the port area, red line range, road grade, traffic capacity, etc., and discretize the radius range of the circle curve at intervals of 20-60 meters;

[0049] 2. According to the curve environment, determine the congestion perception parameters such as the driver's sight distance at different positions and the distance length after discrete;

[0050] 3. Determine the parameters of the ACT-R model according to the curve environment in the port area and the forecast data of road traffic flow;

[0051]4. Carry out simulation experiments on curves with different circular cu...

Abstract

The invention belongs to the technical field of port road design and relates to a port area bend linear design method based on ACT-R, comprising the following steps of: estimating a range of a bend circular curve radius, and dispersing the bend circular curve at intervals with an interval of 20-60 meters; determining visual ranges of a driver at different positions and a distance length after dispersion according to the bend environment, and establishing a traffic jam perception parameter; establishing an adjacent vehicle position and signal perception parameter; establishing a tactile perception parameter; describing a possible action of the driver driving in a port area bend; designing an utility evaluation function of the action of the driver; determining parameters of an ACT-R model according to the port area bend environment and road traffic flow forecast data; carrying out an emulation test on dispersed bends with different circular curve radius, and selecting a scheme with optimal comfort degree on the basis of satisfying the bend design traffic capacity. Compared with the traditional method, the port area bend linear design scheme obtained by adopting the design method more accords with the port area traffic characteristics.

Description

technical field [0001] The invention belongs to the technical field of road design in a port area, and in particular relates to a curve design method in a port area. Background technique [0002] Today, with the development of regional economic linkages becoming more and more extensive, ports, as the main window of the city's foreign trade, have become the focus of urban development planning. In recent years, new port planning and design, and old port reconstruction and expansion projects are in full swing across the country. However, the planning, design and construction of the port area are faced with many problems, namely, the reasonable forecast of road traffic demand in the port area, the treatment technology of road subgrade, the design specifications of the road in the port area, the reasonable scale of the road network in the port area, and the post-design evaluation of the road. Constraining factors for rapid port planning and construction, traditional traffic plann...
