This program is implemented for proving the theory in my bachelor thesis Public-Transit Data Extraction from OpenStreetMap

ExtractionFromOSM

This is the source code of my bachelor thesis "public-transit data extraction from OpenStreetMap Data"

Introduction

Built a network using public-transit data extracted from OpenStreetMap data in Europe and Planet, then completed its inside information through solving various problems, such as wrong orders, existence of gaps, missing labels, poor structure, using bidirectional A*, A*, Dijkstra, SVMs, R-Tree, DFS, finally transformed the network into a General Transit Feed Specification feed which simulates a transport system and can be displayed in TRAVIC. This feed and software OpenTripPlaner together build a public-transit- combination query system for the whole Europe as well as the Planet.

Results

there are four pictures which show the results, you can find them inthe folder

Run the program

To run this program you need to download a osm file from OpenStreetMap

Get the code

git clone https://github.com/zhiwei2017/ExtractionFromOSM

Generate executable file:

make
./ExtractionFromOSMMain [Address] [Mode] [ExtendRadius]

Address: paricular address of osm-file Mode: use the extend mode (Y/N). The default value is "N" ExtendRadius: if using the extend mode, the nodes and ways are loaded into graph when they are in the radius of a route. The default value is 500

Example:

you have a germany.osm file in the directory germany.

you can run the program in non-extend mode like:

./ExtractionFromOSMMain germany/germany.osm N or ./ExtractionFromOSMMain germany/germany.osm

If you run the program with ./ExtractionFromOSMMain germany/germany.osm 50, the program will run in non-extend mode.
