Pedestrian Facilities Inventory Kristin Bennett, AICP Senior Transportation Planner Bicycle, Pedestrian, and Neighborhood Traffic Programs Manager City of Colorado Springs
Project Evolution • Change in City Code – City responsible for sidewalk capital maintenance (March 2005) • Council request to infill sidewalks • Increasing public demand for sidewalks • Increasing number of ADA complaints to DOJ • No pedestrian infrastructure mapped or inventoried, even hard copy • No Citywide Pedestrian Plan
Initial Steps by Staff • Windshield survey of 7 areas of the City • Cost to infill 7 areas estimated • Staff provided initial infill recommendations for $250,000 special allocation • Opportunity to request permission to proceed with Pedestrian Plan and Inventory (recommended in City’s transportation plan ** Had to “sell” concept to internal staff as well as to City Council **
Multi-Department Use of Data • Transportation Planning • Overall City Needs Assessment • Cost Estimation – What is the Total Price Tag? • Application of Criteria to Prioritize Improvements • Support Data for Funding Applications • Traffic Engineering, incl. School Traffic staff • School route planning • Maintenance of crosswalk markings • Project development activities - prioritization
Multi-Department Use of Data • City Engineering • Curb ramp installation prioritization • Sidewalk infill prioritization • Stormwater management calculations (more precise impervious surface information) • Mountain Metro Transit • Analysis tool to recommend priority for sidewalk/ ramp installations along transit routes • Support Data for Funding Applications
Multi-Department Use of Data • Urban Redevelopment • Downtown / Old Colorado City Pedestrian Facilities • Community Development Block Grant (CDBG) funds • Street Maintenance • Sidewalk condition ratings kept on paper now; could be cataloged into Citywide Facilities Inventory • Alley paving – ADA issues at alley/sidewalk intersect;
Combine with Existing GIS Data • Roadway Functional Class • Corridor Traffic Volumes • Transit Routes, Stops (Pads, Benches, Shelters) • Trails, Park Space • School Locations • Neighborhood Strategy Areas (CDBG-fund eligible) • Curb Ramp Installations (database)
GIS Analysis Opportunities • Transit Routes with Missing Sidewalk/Ramps • #’ radius around school sites with Missing Sidewalk/Ramps • Parks/open spaces with missing sidewalk adjacent to them • Principal and/or Minor Arterial Streets with missing sidewalks/ramps • Transit Routes within Neighborhood Strategy Areas with missing sidewalk/ramps • Missing Sidewalk/Ramps along routes that serve both transit and schools…..
Geodatabase Development Steps • Developed parameters for what to digitize • Developed actual geo-database • Tested geo-database with sample sections to determine any changes needed • Intern staff acquired (4 part-time initially, now 3 part-time on this project) • Digitize, digitize, digitize – very detailed work! • Modifications to geo-database as issues arise, interns ID improvements • Field checking required – shadows, trees, etc.
What Are We Digitizing? • Sidewalks – existing, missing with social trail (“goat path”) distinction • Accessible curb ramps • new w/ truncated domes, older era, vertical curb • position (corner or mid-block) • type (perpendicular, diagonal, parallel/dip) • Ramp ID # • Trails not owned/maintained by Parks Dept. • Crosswalks (painted, unpainted, school xing, type of traffic control)
Field Checking – Two Approaches • Manual Field Checking • Identify areas to field check while digitizing • Travel out to locations and check in person • More time and resource consuming (fuel/vehicle) • Video-Based Field Checks • Video log may be available • Some communities have highly detailed video captures of streets (e.g., Cartegraph) • Field check in the office – time/resource savings
Colorado Springs’ Cartegraph Video • Entire City street network (~1,800 centerline miles) being captured on digital video • Cameras on van in all directions so visibility of sidewalk network is excellent (360°) • High resolution • Digitize on one monitor and view field check area frame by frame on 2nd monitor
Other Key Project Information • Only $30,000 assigned to project – necessitated use of interns • Approx. 1,800 centerline miles being digitized • Project about 60% complete – 1,300 hours to date (Feb. 2006 start) • Geographic areas assigned to interns – • Digitize sections • Field check completed sections • Quality control by peer (some checks by Senior GIS staff)
Lessons Learned • Spend time drafting geodatabase before actual creating it (saves time in the long run) • Train everyone in specific application, assumptions • Routine meetings to address issues, answer questions, changes to geo-database • Expect changes will need to be made to database structure as it is used • Accurate facility digitization is time consuming • Talented interns can produce an exceptional product, add value
