compared to manually collected data (0% to 6% for small vehicles, -67% to 36% for medium

vehicles, and -70% to 100% for large vehicles).

A comparison between the tripod-based mounting system and a sign-mounted configuration

was performed for both SmartSensor units. In both cases, the sensor’s accuracy on the tripod-

mounting system was slightly better. SmartSensor HD accuracy for lane volumes was within

95% (tripod mounted) and 85% (sign mounted); directional volume was 99% (tripod mounted)

and 97% (sign mounted); and total volume was 100% (tripod mounted) and 98% (sign

mounted). The SmartSensor 105 accuracy for lane volumes was within 69% (tripod mounted)

and 74% (sign mounted); directional volume was within 94% (tripod mounted) and 81% (sign

mounted); and total volume was within 96% (tripod mounted) configuration, and 87% (sign

mounted).

Based on this study, the SmartSensor HD demonstrated the best overall performance, followed

by the RTMS. The SmartSensor 105 is a first-generation sensor, which has been replaced by

the SmartSensor HD, so its performance is understandably lower than the SmartSensor HD.

When compared with the inductive-loop ATR data collection system currently in place, the

SmartSensor HD showed comparable results. This illustrates the usefulness of using a radar-

based data collection system as a viable alternative to intrusive technologies, and can be

especially useful for temporary data collection.
