• 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.
Milepoint
A vehicle moving speed 30-40 miles per hour.
Re-engineering Road Characteristics Data Collection – current operation
Manual Quality Control
Manual Data EntryDatabase
Choose the routes to collect data with maps
Carry hard-copy maps and pre-inventory for data collection.
Collect RC data on Highway
Record data manually in the field
Goal of Project: Improve Data Quality, Operation Efficiency, and Safety
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, signals…etc.)
Re-engineering Road Characteristics Data Collection – future operation
