FUHRMANN Engineering Inc. (FEI) is providing Field Collection of Traffic Data with the use of Diamond TT4s Road Tubes, NC 300 HiStars, and Miovision Scout Units for various routes and various counties.
Fuhrmann is currently providing services for the following:
- The 24-hour volume/classification counts are being collected with passive magnetic sensors (lane counters). For the state marked route counts, the HiStar NC-300 passive magnetic sensor is being use for most locations. For unmarked routes with previous AADT less than 500, road tubes are being used to collect volume traffic data. For unmarked routes with previous AADT higher than 500, HiStars are being used to collect volume traffic data.
- The 24-hour intersection turning movement counts with vehicle classification data is being collected using a Miovision video collection unit that can accurately extract lane specific volume/classification traffic counts on high volume Interstate routes.
- Access to the web-hosting site, containing the video used to extract the turning movement and traffic data, will be provided to IDOT for download during the period of contract.
