SRTC Releases New, More Visual Maps

Ever wonder about the condition of the local bridges you drive over or which areas of the county have the most vehicle collisions? SRTC is rolling out some new maps that can answer those questions and others related to local transportation.

In 2014, we started using ArcGIS Online technology to create interactive maps to better illustrate information and data such as where construction projects are happening, the location of bicycling infrastructure throughout the county, population and employment centers in the area, and more. This was done in an effort to more fully involve you, the public, in transportation planning and activities.

Now we're expanding how we use online maps and creating new kinds of maps that are less traditional and more visual. For instance, the Transportation Improvement Projects- Before & After map uses photos to demonstrate how area roadways look before and after construction. It also includes the location of each project, a description of it, when it was completed and the project cost.

The Collisions 2009-2013 map is five maps in one. You can choose which “layer” to view (or all five at once) including collisions involving vehicles, bicycles or pedestrians, serious and fatal collisions, or all collisions between 2009 and 2013, the five most recent years of available data.

The Bridge Condition map shows bridges throughout Spokane County that are either structurally deficient (require repair or replacement of components such as cracked or broken concrete, or potentially the entire bridge) or functionally obsolete (the design of the bridge is not suitable for its current use and not able to handle traffic volumes, speeds, size or weight of today’s vehicles).

Other new maps include an overview of the Congestion Management Process (CMP) and the corridors studied in the CMP document, a review of “urban corridors” included in the Horizon 2040 long range transportation plan, and a map of SRTC’s Planning Boundaries and  partner agency’s areas of operation.
