A periodical examines the deployment of alternative parking technologies.
Although technologies such as induction loop detectors installed at parking entry and exit points can be cheaper to implement compared to a single-space parking space occupancy detection system that uses ultrasonic sensors, the accuracy rate of loop detectors can be an issue at times when vehicles are closely following each other during peak periods at entry and exit points.
An Austrian company that designs and installs advanced parking guidance systems for airports, hospitals, malls and casinos around the world reported that a single-space parking space occupancy detection system that uses ultrasonic sensors with easy to spot red or green LED indicator lights mounted above each parking space in parking garages can cost between $300 and $500 per space to install, depending on local labor costs.
