Using GIS for Transit Analysis

Interwest provides GIS services to public agencies to analyze route changes and ridership. The City of Elk Grove is conducting a Comprehensive Transit Analysis that will be used to define the future of transit in the City.

Interwest GIS created an interactive web application using Esri's Web AppBuilder to show existing and proposed routes. As part of the analysis, the City's transit team developed a "service plan working paper" that included exhibits showing the recommended service improvements. This web app displays the information in an interactive form that allows the public and council members to review the proposals with more flexibility.

The web map also needed to display the relationship between routes and major employment centers, schools, and hospitals.

Interwest GIS worked with IBI, the City's Transit Consultant, to convert the proposed routes from Adobe Illustrator exhibits into a format that could be published to an ArcGIS Online web map. Special attention was placed on the zoom scale of the application to support the visual requirements of offsetting routes to display multiple features while ensuring it wasn't possible to zoom in far enough for the routes to appear not on the roadway.
