Geographic information system and method for monitoring dynamic train positions
First Claim
1. A method for displaying geographic roadway data, geographic track data, and geographic position data for a train, said method comprising:
- employing a geographic information system database;
entering static roadway data in said geographic information system database;
entering static track data in said geographic information system database;
controlling or monitoring a plurality of track sections with a plurality of track circuits;
determining a first track section of said track sections occupied by said train;
determining at least one second track section of said track sections, which has been cleared to be occupied by said train at a future time;
determining geographic starting and ending positions of said first track section;
determining geographic starting and ending positions of said at least one second track section;
displaying geographic information regarding said static roadway data and said static track data from said geographic information system database;
determining first geographic information regarding said first track section occupied by said train from said geographic starting and ending positions of said first track section and from said geographic information system database;
determining second geographic information regarding said at least one second track section from said geographic starting and ending positions of said at least one second track section and from said geographic information system database; and
displaying said first and second geographic information regarding said first track section occupied by said train and said at least one second track section with said geographic information regarding said static roadway data and said static track data.

Abstract
A geographic information system (GIS) displays geographic roadway data, geographic track data and geographic train position data. The GIS includes a GIS database having static roadway and track data. A computer aided dispatching (CAD) system includes a task to determine an occupied track section. A web server includes a first routine determining geographic starting and ending positions of the track section, a second routine displaying geographic information regarding the static roadway and track data, and a third routine determining geographic information regarding the occupied track section from the geographic starting and ending positions of the track section and from the GIS database. A client system communicates with the web server to receive and display the geographic information regarding the static roadway and track data, and to receive and display the geographic information regarding the occupied track section with the geographic information regarding the static roadway and track data.
