Bus priority signal timing method based on running schedule

Abstract

The invention discloses a bus priority signal timing method based on a running schedule with the adoption of a computer program. The method can solve the shortcoming that the prior bus priority signal timing technology does not take into account of bus punctuality rate, so as to realize the maximization of the punctuality rate of city buses. The method comprises the following steps of collecting information; calculating the bus travel time (T') and the delay degree (di) deviating from the schedule; utilizing the calculation and the current signal timing of an intersection to obtain the light color situation of the bus when arriving at a stop line and select the bus signal priority way according to the different light colors by a control center; calculating the total people delay variation (PI) of the intersection; and generating a new signal timing proposal by the control center. Wherein, the bus travel time comprises two parts of a bus dwell time (Td) and a bus drive time (T); the bus signal priority way comprises two priority ways of lighting a green light in advance and prolonging the time of the green light; and the total people delay is divided three parts of bus stop passenger delay, total bus vehicle people delay and total social vehicle people delay.

Description

technical field [0001] The invention relates to a signal timing method used in an urban traffic management control system, in particular to a bus priority signal timing method based on a running schedule. Background technique [0002] The bus operation timetable is a regular and recurring driving plan formulated according to the law of urban bus passenger flow, according to the number, direction and time of passenger flow. No matter from the perspective of passenger demand, vehicle operation or manager's scheduling management, the punctual operation of each bus vehicle based on the bus schedule can maximize the social benefits of the bus system and passenger travel. Using technical means to ensure that the operation of buses achieves a relatively high punctual rate is what the public expects, and it is also what the bus service level should meet. [0003] At present, the research on the bus schedule mainly focuses on the determination of the schedule, that is, to determine ...
