To collect various types of traffic data to meet the Federal Requirements, field technicians have to enter
;
the roadway to anchor the road sensors while traffic is moving at highway speeds. On high volumes
;
routes this can be a very time consuming task, and cold wet pavements will not permit the use of existing
;
sensors that use tape to stick to the pavement. The requirements for the off road sensors are: collecting
;
3 or 4 lanes of data from the side of the road, needs to be in place for 48 hours, portable and set up
;
within one-half hour, set 60 to 75 locations per week, and low power consumption so that they can
;
operate on a small gel cell battery. The traffic data required are: FHWA thirteen (13) vehicle
;
classifications by axle type, speed by vehicle type, and total volume.
