Specifications include, but are not limited to: Methodology Media access control addresses (“MACs”) for each passing device will be recorded and timestamped (with probable multiple MACs removed). These will then be matched with MACs at places with significant truck activity locations to compute speed and activity by time-of-day. Latitude and longitude, a nearby street address or intersection, in addition to digital photographs, will be supplied to the vendor for each monitoring location. Requirements for field equipment Each Bluetooth detector shall be able to run for at least seven (7) days (about 170 hours) without needing any charge or other intervention. All field equipment must be able to operate in the rain, extreme heat and cold, and be resistant to the normal dust, dirt, and grime of the roadside environment. It must be possible to secure all equipment to structures normally found on the roadside (such as bridge piers, light poles guardrails – but not trees and not utility poles). Required outputs The COG staff has considerable technical ability to process data downloaded from the detectors, but the vendor will be asked to process data as part of this project. Factoring of data is not required. Outputs requested include raw MAC addresses observed at each location, matching MACs and computed travel times.
