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
SLIDE 4
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

SLIDE 7
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
SLIDE 8
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
SLIDE 9
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

SLIDE 15
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
SLIDE 16
Develop Traffic Signal Editor Application
ArcGIS Editing Template
SLIDE 17
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
