Technology advancement is a necessity in today’s world. It has a significant impact on both quality of life and the economy of modern societies. Information communication technologies have gained increasing attention and importance in modern transportation systems. Parking management systems are, therefore, a key element in developed or developing countries. In land-scarce Singapore, Intelligent Transport Systems (ITS)’ sophisticated traffic and control systems maximise road network efficiency capacity as well as monitor and manage traffic flow.
This article introduces a new approach of parking system by using Wireless Sensor Network (WSN) technology equipped with ultrasonic sensors. The sensors detect the passage of vehicles on these roads and communicate this information to a data centre, thus making it possible to know the number of vehicles in the controlled zone and the occupancy levels in real-time. The system operates by monitoring the availability of the parking space and making the information collected available for patrons and car park operators singapore. The information gained from the detection sensor and calculation from the shortest path algorithm is used to guide patrons to parking spaces.
The emergence of Wireless Sensor Network (WSN) which consists of spatially distributed autonomous devices using sensors has contributed to a wide variety of applications. The ability to provide wireless localized measurement with low power consumption has driven the authors to propose a smart parking system which employ WSN technology. Radio-Frequency ID (RFID) sensor, a conventional type of sensor, is used for smart parking and for detecting vehicles to allocate space for parking.
Based on the selected destination, the system will calculate the nearest empty parking space nearest to the entrance chosen using shortest path searching algorithm. This is done assuming patrons will prefer to park nearest to the building entrance since less walking distance is needed. Following the calculation made by the system’s nodes, the calculated empty parking space is reserved with a unique ID embedded in a RFID tag. Then, the ID and reserved parking space is updated in database. The drivers will be presented with the RFID tag via a ticket dispenser and the solution route to their reserved space.
In the case the reserved parking space is not utilized, the reservation will expire after 10 min. The system calculates the time of reservation of every parking space and reset the status of the space to available when the time is due. The system will assume the patron parked the car at other parking spaces.
Sensors will play a vital role for ITS in the future. Their usage enables the development of a wide variety of applications for traffic safety, parking control and driver assistance. Sensors provide the mechanism to data acquisition related to solving some of the problems that past and current car park management have been facing.
