Sidewalks are key to a vibrant city life, serving as both social and economic conduits for pedestrian traffic. Safe and well-maintained sidewalks are a basic and necessary investment for cities, and thoughtful sidewalk design can encourage pedestrian traffic by making it more attractive. In today’s world of bike share, car share, freight loading, food trucks, bioswales, pedestrian safety bulb-outs, ride-hail, delivery trucks, and other competing uses, managed curbs incorporating ramps, sensors and other new technologies can help meet ADA requirements and enhance the user experience. 

For many municipalities, a daunting first step is to accurately catalog existing sidewalks, so that transportation planning staff and other local stakeholders can identify gaps and ways to improve pedestrian mobility and safety.  Emerging technologies can help cities dynamically shape and manage curbs by inventorying curbside uses and regulations, building smart partnerships with the private sector, and using new technologies to collect data.  Owning and managing curbside asset data allows cities manage the future of the curb, as the private sector starts to catalog curbside data for their own traffic management. 

Curb data collection areas:

  • Sidewalk zones

  • Sidewalk design

  • Streetside trees and foliage

  • Clear zones


  • City, State, and Regional Transportation Professionals

  • City Engineers

  • City/Urban/Transport Planners

  • GIS/Geospatial Professionals & Analysts

  • Mapping Technology Decision Makers

  • Smart City Innovation Leaders

  • State and Local Government CIOs, CTOs, and IT directors

  • Public Works Directors/Asset Managers

  • Parks & Recreation Directors

  • University/Enterprise Asset Managers

  • DOT Officials

  • Traffic & Transit Engineers/Design Consultants

  • Transit Planners and Administrators

  • Drafters & Surveyors

  • Geospatial Application Developers

  • Project Engineers & Managers

  • Public Works/Roadway Maintenance Supervisors

  • and others ...

Key asset mapping elements:

  • ADA Compliance

  • Vision Zero

  • Long Term Planning

  • Pedestrian Assets

  • Painted Markings

  • Movement Data/Footfall Survey Data

  • Cell Place Data

Join this session to learn about technologies that allow for comprehensive and accurate mapping of sidewalks and crosswalks, and how to access funding under recent Infrastructure bills for relevant technological upgrades.

Basic ADA Requirements for Public Entities and how GIS ties into Self-Evaluations and Transition Plans

Greg A. Martinez, Senior Transportation ADA Designer, HDR

Greg Martinez will discuss the background of the ADA and other civil rights laws, ADA Title II responsibilities for state and local agencies, and settlements under the ADA.  He will focus on requirements for ADA Self-Evaluations and Transition Plans, including transition plan elements and how GIS helps your Self-Evaluation and Transition Plan process for curb ramps, sidewalks, signalized and non-signalized intersections and pedestrian pushbuttons.

State and Local Government Asset Identification Obligations via an ADA Transition Plan

Chris Bell, Board Member, American Council of the Blind

This session will address the ongoing obligation of state and local governments to regularly conduct a self-evaluation of physical and other barriers in the public rights-of-way and facilities and to plan for the removal of physical barriers through an ADA transition plan. The session will highlight the ACB’s litigation in NYC and Chicago for the failure to install APS, a barrier which should have been recognized and resolved over the last 30 years by self-evaluation and ADA transition planning, as well as the risk of other existing litigation for a government’s failure to remove barriers which have cropped up since the last evaluation.

DeepWalk develops scanning software to simplify sidewalk ADA Transition Plans for backlogged public works departments. The DeepWalk Process is simply to scan the sidewalk system, plan using DeepWalk's standard templates and deliverables,  and Implement with our automated construction documents. We are a team of civil and computer engineering graduates from the University of Illinois at Urbana-Champaign. We started DeepWalk based on over 100 interviews with municipalities and consultants from across the country. Our focus is solving the logistical, planning, and engineering challenges that prevent accessible design. To do this, we work closely with municipalities and ADA experts to tailor our software directly to their needs.
