A combined travel route search method and system for urban comprehensive traffic network

Abstract

The invention discloses a combined travel route search method and system oriented to an urban comprehensive traffic network. Traffic network, carry out topological processing on the network at each level, divide its topology into indivisible nodes and road sections, and set the time impedance and cost impedance of nodes and road sections, set the screening principle of feasible travel routes, according to the input The location coordinates of the origin and destination points are searched for combined travel routes according to the three classification standards of travel time, travel cost, and transfer times, so as to provide travelers with diversified travel options. The invention solves the defect that the existing combined travel route search method is limited to a single traffic network and is not suitable for urban comprehensive traffic networks, and is more in line with the concept of travel as a service and the development trend and inherent needs of urban smart traffic.

Description

technical field [0001] The invention relates to the field of urban intelligent transportation, which is the specific application of new generation information technology in urban transportation planning, construction and management, and in particular to a combined travel route search method and system for urban comprehensive transportation networks. Background technique [0002] In 2014, the EU Intelligent Transportation System Conference held in Helsinki, Finland, proposed the concept of Mobility as a Service (MaaS for short). MaaS has become a hot topic in the field of urban smart transportation and is rapidly rising around the world. MaaS is to provide travelers with combined travel route recommendation services and tailor-made travel packages by integrating different modes of transportation, thereby enhancing the happiness of travelers. As the basic technology of MaaS, combined travel route search method has attracted more and more attention from academia and industry. ...

In terms of search methods for combined travel routes, most of the existing travel route search methods are aimed at a single transportation network. A type of combined travel route, but the road network, slow traffic network and public transport network have not been integrated. At present, the combined travel routes of driving + subway and driving + bus cannot be searched, and only in some areas can search for travel routes. There are certain limitations in the combined travel paths of walking + subway, cycling + bus

In terms of combined travel route set recommendation, scholars at home and abroad often use the method of weighted summation to comprehensively calculate the three major attributes of the combined travel route, such as time, cost, and comfort, as generalized costs, which makes it difficult for travelers to intuitively calculate the cost according to their own needs. Judging the pros and cons of combined travel routes
