Wouldn’t it be great if we could update network attributes based on street names rather than node numbers? 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?
