Abstract
The number of vehicles in cities has increased dramatically due to rapid economic development. However, the infrastructure for accommodating these vehicles has grown relatively slow. Alleviating the pressure on the urban transport system and solving the ‘parking difficulty’ problem have thus become hot topics recently. In this paper, an intelligent parking system based on geomagnetic field variations is presented to solve this problem. An algorithm which detects the presence of vehicles in parking spaces in a parking lot is designed and field test results are presented. Our results show that this system has an acceptably high accuracy with low cost, high feasibility, high efficiency and hence is recommended for wide use.
Highlights
With the rapid development of the economy, vehicles have become an indispensable tool in people’s daily life
In order to acquire accurate information of parking status, a magnetic field sensing technique is adopted to detect magnetic variation in the parking spaces in real time, since ferromagnetic materials are magnetized when placed in a magnetic field and magnetized ferromagnetic objects are capable of changing the surrounding geomagnetic field
(1) We choose a kind of effective and innovative sensors to detect the parking status, which could be further leveraged for smart parking system design
