The equipment used in the pilot test included the following: Vehicle weight was obtained from the Air-Weigh 5800 (Fig. 6). Fig. 6. Air-Weigh 5800 Weather information was collected through the Vaisala WXT510 Weather Transmitter (see Fig. 7). 12
Fig. 7. Vaisala WXT510 Road surface temperature was measured by the RoadWatch (see Fig. 8 and Fig. 9) Fig. 8. RoadWatch Equipment 13 Fig. 9. Temperature Sensor Mounted on Side Mirror The following figures show the NGK NOx/O2 sensors (Fig. 10); and the Omega exhaust gas temperature probe (Fig. 11).
