The Internet of Things (IoT) is transforming the technology landscape, revolutionizing every facet of life. Smart devices collect data on the number of steps we walk, helping people live healthier lives or adjust the temperature in a home to conserve energy. Sensor technology is a key component, increasing the capabilities of smart devices in every field. In Smart Parking, sensors reliably detect the presence or absence of a vehicle in a parking space, allowing cities to more accurately understand parking demand while providing the capability to:
- Access real-time and historical occupancy data
- Reset the meter to zero time when a vehicle leaves a parking space
- Prevent meter feeding, thereby promoting space turnover
- Offer courtesy time, resulting in positive public perception of the meters
- Enable demand-based and progressive rate structures
- Optimize enforcement
These features can assist municipalities in making data-driven policy decisions, increase revenue, and maximize program efficiency. But with the high visibility of parking programs and the political nature that is often involved, the need for accuracy is critical.
A Sensor’s Algorithm
Vehicle detection sensors most commonly utilize magnetic or radar-based techniques to sense movement and objects. When installed on a city street, as opposed to remaining in a closed and controlled environment, the variables increase. On-street parking is far more complex than off-street because there is more activity to influence the sensor.
