Wouldn’t it be great if we could create transit line and stop data based on street names rather than node numbers?

  6. Good News: GIS might help! Route Systems • Route = ordered groups of links • A bus route, a named street Linear Referencing • Procedures for locating “events” along a route • Bus stops, intersecting roadways, number of lanes, traffic counts, or any other route attributes

  7. Highway Data Translation Tool A non-GIS tool that automatically translates: • From data with location specified using street name syntax: • To the same data with location specified using one or more a-to-b node links from the input highway network Standard DBMS software is used to join the “translated” link-level data to the network link data and to manipulate link attributes.

  8. Transit Data Translation Tool A non-GIS tool that automatically translates to and from: • Transit line data (route name, mode, headway, and delay) and stops specified using street names: • Transit line and stop data specified using node strings from an input highway network: • Allows users to quickly and accurately move transit lines and stops from one network to another having different node numbers.

  9. Conclusions Street name based coding is feasible • With or without GIS tools Street name based coding is a good idea • It is node-independent • It reduces coding errors • It documents attribute changes • It encourages checking Forum for modeling related shareware and open source software?
