Road Inventory Data Collection Re-engineering

• Collected Data Items (more than 50 items)
• Street Names.
• Pavement width, number of lanes, etc.
• Bike path, sidewalk, etc.
• Signs including Stop sign, Speed Limit, Milepost,
  etc.
• Traffic signals
• Intersection, interesting street names, etc.
• Features include
• Point features Linear features
• Technologies to be used
• Database management, GPS/GIS real-time navigation
  and mapping, Real-time Distance Measuring
  Instrument (DMI), Digital Camera, and image
  processing.

A vehicle moving speed 30-40 miles per hour.

Re-engineering Road Characteristics Data
Collection current operation
Goal of Project Improve Data Quality, Operation
Efficiency, and Safety
Carry hard-copy maps and pre-inventory for data
collection.
Choose the routes to collect data with maps
Collect RC data on Highway
More than 100 data items to be collected at one
milepoit (Number of lanes, pavement width,
overpass, sidewalk, bike path, signs such as stop
and speed limit signs, signalsetc.)
Manual Data Entry
Manual Quality Control
Database
Record data manually in the field
