Background 55 47 “The Friendly MPO”
Background Project purpose & need: Planning for operations • Data-driven planning • Project screening • Unknown signals • Knowledge preservation • Solution: GIS Signal Inventory Parallel project : Traffic Data Collection Follow-up projects : Regional Signal Timing Initiative SJTPO-funded signal improvements
RFP Process Three counties participating: Atlantic County 164 signals • Cape May County 232 signals • Salem County 35 signals • 431 total Competitive RFP process with the following scope of work: Data collection : signal controllers, • supports, indications, detection, pedestrian facilities, and more Inventory : all field data + signal plans, • timing plans, etc. GIS : online, accessible, user-friendly • Contract awarded in July 2016 to Taylor, Wiseman & Taylor with subconsultants JMT and AEA
Project Development Moving forward: smarter signals Demand-responsive • Communication & coordination • Computerized (CTSS) systems • Adaptive systems • Bike + ped accommodations • Regional approach to systemic signal improvements for: Better signal maintenance • Safer intersections • Improved traffic flow •
Overview Confirmed/ Modified Locations List • 431 Locations: 3 Counties • 35 Salem, 164 Atlantic, & 232 Cape May • 258 Traditional Traffic Signals • 173 Beacons: Intersection Control; • Pedestal or Mast Arm; RRFB; Warning;
Inspection Inventory Data List Compiled Facilities Data List • to be Inventoried Established Categories(Icons) • Excel • Organized Facilities by • Category: Location, Controller, Standard, Mast Arm, Head, Sign, Push Button, Beacon, ADA Ramp, Crosswalk, Solar Utilized Pull Downs • Stage of Review by Color • Open Review Comments •
App Icon Development Determined Critical Categories (data list) • Organized All Facilities into categories • Simplified Icons for field data collection • Color Coded Icons based on Project Stage • Worked with JMT to develop App early in • project to be mobilized in field using IPads with App, resulting in greater efficiency and less data error
Data Collection Workflow: In House: Requested, gathered, & organized signal • plans & timings Acquired Miovision traffic counts for • available locations Attached plans, timings, and counts at • each location on App Prepopulated App in office with plan info, • speed limits, and Google Earth review for ease of field data collection Field: Utilized IPads with backup batteries • Ran a Pilot Program with 9 various • locations covering different categories in all 3 counties Changed facility color in field as • completed or as questions develop Reviewed and checked all field data as • generated
Data Collection – In-House and Field • Leveraged JMT’s ArcGIS Online Organization • Hosted Services • Web Map / Collector Application In House & In the Field Collection Collector Review Collector Hosted Inventory Dashboard Feature Service Custom Application
Data Collection – Quality Control • Web Map and Web Application
Data Collection – Project Tracking • Operations Dashboard
Custom Web Application APP • Custom Esri Leaflet Application • Using Esri Hosted Services
Inventory Maintenance Add & Adjust Inventory Editor application •
Develop Traffic Signal Webmap ArcGIS Online Organization Transfer data and post to AGO • Set up items on AGO and on web server, copy symbology • Create a webmap from the final hosted feature inventory •
Develop Traffic Signal Editor Application ArcGIS Editing Template
SJTPO Traffic Signal Inventory Highlights/Concerns Accessible to all SJTPO participating agencies • Complete inventory of agency traffic control devices • Agency knowledge transfer of maturing inventories • Editor application still a bit clunky • Editor application development continues with the hope to soon • include a faster data backup/restore solution
