ITS Design Service
• Tasks– ITS element and supporting
infrastructure location– Cabinet location– Power source– Communication source– Conduit routing– Safety Consideration
Why is Field Survey IMPORTANT?
• Base Mapping• Design Options
– Serviceability– Power and communication– Cable routing– Sight line obstructions
• Engineering Cost Estimations• Operation & Maintenance• Future Upgrade & Expansion
What is NECESSARY for a Field Survey?
• Supporting personnel from related agencies and the permission to conduct a survey
• General equipments– Field survey forms– Bucket Truck– Digital camera– Camcorder– Measuring wheel, and
• Revisiting sites whenever needed
Field Survey Products
• Photos and Videos– Logs– Visual records– Redundancy of field
information– Field of view range
• Survey forms– Device profile– Position– Terrain and slope– Roadway/road side
conditions– Serviceability information– Potential communication
methods– Potential power source
location
Summary
• A well conducted field survey is the first step to a good ITS design.
• Be prepared to go back. It usually happens.
