The Development of an Integrated Geosimulation Environment for Public Transit Analysis and Planning

Abstract

-This paper describes an integrated software environment for multi-modal public transit simulation based on the principles of geosimulation that integrates the capabilities of multi-agent systems, GIS and interactive visualization. The goal of the presented research is to explore possibilities of population in one of Latvia's planning regions, called Vidzeme, to access state/municipal and other services by using public transport. In order to achieve the defined goal, an integrated simulation environment for public transit analysis and planning is developed.

GTFS bus stop mapping to the OSM network

“…A handful solutions have been provided in the past. Lektauers et al [3] mention a "tool to associate stop facilities to network nodes" without any details (in the context of an integrated MATSim-based simulation). Li [4] exploits the relational information between adjacent bus stops.…”

“…Many published GTFS datasets do not contain the optional shape file. 3 Furthermore, the shape file only provides information on the geometry but not the topology. The shapes.txt file in GTFS contains tuples s, x, y, o where s de-30 notes the sequence identifier, x and y denote longitude and latitude respectively and o is the offset of the point in the sequence.…”

“…Hence, the shape files cannot be used to determine the bus stop locations from geometry and ordering. 3 Following GTFS data sources where checked: De Lijn (Belgium), RATP (France), Fritz Behrendt OHG (Germany), Günter Anger Güterverkehrs GmbH & Co. Omnibusvermietung KG (Germany), Haru Reisen OHG (Germany). These data sources are available on http: //www.gtfs-data-exchange.com/.…”
