Embodiment Construction

[0061] In order to achieve the above-mentioned purpose, the method for illustrating the operation capacity of bus-only lane intervals is carried out in the following steps: 1.1 Through actual investigation or data provided by the transportation department, determine the basic elements required for drawing the bus space-time map, including bus interval operation Time division, bus stop time at nodes (intersections, stops), node geometric features, bus stop positions, node spacing, intersection signal cycle duration, green light duration, etc. (see the attached manual for details) figure 2 example).

[0062] 1.2 Graphics drawing and output: The drawing of the bus space-time diagram is programmed by VBA and completed automatically by AutoCAD. First draw the base map of the bus space-time map (see the attached manual for details) image 3 example). In this method, according to the survey data, a section of the actual time-space diagram of the bus operation is drawn and output i...

Abstract

The invention discloses a method for illustrating bus-only lane interval operation capacity, a bus space-time illustration method for short. The method comprises the following steps of: designing basic elements of a bus space-time diagram according to a bus-only lane and a bus flow running characteristic of an investigation interval and drawing the conventional running track of buses, acquiring apull-in failure rate of each bus stop and average delay time of each signal intersection according to the diagram and judging whether running adjustment is necessary for the investigation interval; determining average stop time of each stop station and key stop stations according to basic data respectively if the running adjustment is necessary for the investigation interval, when the buses pass through the signal intersection in an organized operation mode in an ideal operation state of a plurality of stopping spaces and signal timing of the intersection is newly performed, representing a timing scheme on the bus space-time diagram and drawing the bus space-time diagram close to key nodes so as to expand the bus space-time diagram in a full-time operation period of the entire interval; and finally acquiring the bus-only lane interval operation capacity of the interval according to the diagram.

Description

technical field [0001] The analysis method of the operation capacity of the bus lane interval is a very important issue in the field of bus planning, design and operation management. This method is based on the analysis of existing research results, and proposes a method of adjusting the operation capacity of bus lanes by graphical analysis, which is more intuitive than using formula calculations, and can assist bus timetable preparation and bus dispatching The work provides a basis for the scientific, reasonable and orderly use of bus lanes by operating vehicles on various bus lines in the city, and belongs to the field of urban passenger transport planning, design and operation management. Background technique [0002] As one of the main measures to implement bus priority, bus lanes have achieved remarkable results in realizing the priority of the bus. Open up bus-only lanes, realize the separation of buses and social vehicles, reduce the impact of social vehicles on buse...
