||The purpose of FMCSA’s SmartPark initiative is to determine the feasibility of a technology for providing truck parking space availability in real time to truckers on the road. SmartPark consists of two phases. Phase I was a field operational test (FOT) to determine the accuracy and reliability of a technology for counting truck parking space availability. Phase II focuses on disseminating truck parking availability information and determining whether the technology can be deployed to divert trucks from a filled to an unfilled parking area. This document is the final report for Phase I. In Phase I, three combinations of different technologies were subjected to field testing to ascertain their feasibility for determining truck parking space availability in real time: side (SID) scanners, overhead (OH) scanners, and light curtains (CURs), each combined with Doppler radar.
The most optimal configuration of technologies is a SID scanner combined with Doppler radar at both the ingress and egress points of the selected truck parking area. Other findings and recommendations pertain to the trade-off between accuracy and the frequency of ground-truth correction, qualitative reporting of truck parking availability to address uncertainty when the parking area is nearly full, required time for stabilizing the system, use of a vehicle classification scheme that reduces the number of vehicle classes, increased bandwidth in data transmission, and enhanced surveillance and monitoring with closed circuit television (CCTV) cameras.
