Seattle SMART Grant Digital Commercial Vehicle Permit Project: Maps and Data

What's New?

Stage 1 of the project has now concluded! This means that API and web map access will be turned off as the team prepares to launch Stage 2 of the project. Please stay tuned for updates on when new maps and data will be available for use.  As always, please reach out to us at curbSMART@seattle.gov with any questions. 

Project Area Digital Curb Inventory

A key goal of the SMART Grant Digital Commercial Vehicle Project was to test out the capabilities of the open-source and publicly accessible, Curb Data Specification (CDS) managed by the Open Mobility Foundation (OMF). For our project, CurbIQ created a web map of our project area and an application programming interface (API) feed of curb zones and policies, all in CDS format. The API allows curb information to be published digitally in a structured way that’s designed for computer programs to access. 

(Note, this project and the data provided in the links below are a work in progress and may include errors.) 

Project Area Web Map 

The mapping tool showed the locations of different types of curb space such as load zones (commercial, passenger, standard), paid parking, and the times these spaces were available for use in the project area. The map also showed real-time availability of 25 commercial vehicle load zones. 

Curb Data Specification Curbs and Curb Policy API Endpoints 

We are no longer providing access to the API endpoints as the Stage 1 project has concluded. Please be on the lookout for future announcements on Seattle curb management web maps and data as we prepare for Stage 2. 

For more advanced users looking to access the more granular data behind the web map, we provided an API to access SDOT’s curb regulations and parking space inventory in a machine-readable way. The API is primarily written in CDS format to ensure the data is compatible with other CDS users around the world. Where it differs from CDS, CurbIQ has noted in their API documentation link below.
