Summary

The Curb Management Working Group (WG) is responsible for delivering data and API specifications that facilitate the inventory, exchange, and analysis of information describing curb assets and regulations. This include dynamic information such as occupancy/utilization, pricing, and regulations that are set or adjusted using use cases, policy, and metrics.

The WG conducted its work in two phases whose timeline was determined by the Working Group Steering Committee (WGSC): a Discovery phase and an Implementation phase. These phases are now complete as we have started publishing official CDS Releases.

Purpose

Urban curb is a valuable, limited, and often under-managed part of the public right of way. Curb demand comes from passenger pickup/drop off, traditional and on-demand delivery services, transit priority, active mobility (e.g walking, biking and micromobility), and parking for personal vehicles and micromobility devices. While cities have made some progress in digitizing their curb and other physical assets, technology and data offer new tools to proactively manage curbs and sidewalks, and in doing so deliver more public value from this scarce resource. Cities often lack a digital index or map of curb regulations, relying instead on signs and paint in the right of way. Curb data standards could provide a mechanism for expressing static and dynamic regulations for curb use. New approaches to curb usage fees could enable more goal-driven management strategies. OMF is well positioned to help cities use dynamic digital curb regulations, which could allow cities to manage the curb and adjacent infrastructure on sidewalks within the public right of way in real time and communicate the evolving restrictions, permissions, and pricing via a data feed or API.

OMF could support this type of policy innovation by specifying APIs within MDS to support policy approaches such as:

  • Dynamic ridehail pick-up/drop off spaces during special events
  • Conversion of on-street vehicle parking spaces into designated micromobilty parking
  • Time restricted freight/delivery zoned to increase efficiency of urban logistics
  • Pricing of curb access or parking on a static or demand-responsive basis
  • Dynamic or flexible curb use regulations that respond to changing use patterns
