Everything under control thanks to networked parking space sensors

Bosch parking sensors identify parking violators quickly and safely

No parking permit, exceeded maximum parking time, incorrectly adjusted parking disc or parked right in the no-parking zone: Some of the parked vehicles are always parked in violation. The challenge today is to locate these parking violators in order to carry out targeted checks and sanction violations as far as possible. Parking sensors are recommended as a time and cost-saving alternative to personnel-intensive checks, which are often carried out according to gut instincts or on fixed routes: They independently monitor the occupancy of parking spaces and automatically determine the particular parking duration. The principle is as simple as it is effective: A sensor that continuously checks whether and for how long a vehicle is parked is attached to each parking space. The data are transmitted in short intervals via radio to a control center where they are processed and evaluated. The results show precisely where vehicles are parked in violation, allowing for on-demand checks.

Parking sensors with high accuracy

In order to achieve an overall view of occupancy and parking time, virtually in real time, the parking sensors must provide a very high level of accuracy in order to avoid corrupted data and thus false alarms. Bosch has therefore tested and optimized its parking sensors not only in the laboratory but also in various field trials. Thousands of parking procedures were carried out and analyzed with the Bosch Parking Lot Sensor, both in open parking spaces as well as in parking garages. To exclude disturbances by, for example, neighboring vehicles, Bosch carried out dozens of parking procedures at the same time and used very different vehicle types. The evaluation of several hundred thousand data records attests to the excellent detection rate of over 97 percent by the Parking Lot Sensor from Bosch.

Free customer parking spaces thanks to parking space sensors

Parking lots of shopping centers are often blocked by commuters and residents. The result: Customers find it difficult or impossible to find a parking space, resulting in massive dissatisfaction. Parking sensors provide a highly efficient way to reliably monitor the maximum parking time that is often limited to a few hours. Since every parking procedure is registered, the parking time for each vehicle can be recorded to the minute. For the targeted tracking of parking violators, there is an app that displays a plan of the parking lot on a tablet and visually displays free or occupied parking spaces, as well as the parking time, via a traffic light system. Depending on the exceeded parking time, various measures can then be carried out - from issuing information on warning fines or penalties all the way up to towing. Another advantage: The frequently practiced moving and replacing of the parking disc to extend the parking time remains ineffective.

Parking sensors allow targeted checks

The procedure described above can be easily transferred to paid parking lots, street sections with parking meters and areas with free short-term parking zones. Where and how a vehicle is parked in violation depends on variable factors, such as events, day of the week, time of day and weather. Clear predictions are therefore not possible. Parking sensors replace the "gut feelings" of the inspectors with objective data. Operations and routes can be tailored to the occasion and thus arranged much more efficiently than before. In an expansion stage, for example, a comparison with central ticket machines or collective parking meters is conceivable. In this way, the ratio between expired parking permits and actually parked vehicles and their parking times can be determined. Zones with a particularly large number of parking violators are recognizable at a glance. Here too, the basis for a targeted checking and sanctioning is laid.

Parking sensors keep parking spaces for the handicapped free

To curb the excessive unauthorized use of parking spaces for the handicapped, a major European city relies on Bosch parking sensors in conjunction with a smartphone app. Holders of handicap parking placards can easily authenticate themselves after parking by using the app. The city then knows immediately that the vehicle is legally parked. If the authentication is missing, it can be assumed that the vehicle is parked in violation and is without authorization. As a positive side effect, the app shows the way to the next free handicap parking space. Thanks to the parking sensors, the availability is known throughout the city.

Free restricted areas

Parking sensors are also very suitable for monitoring restricted areas, such as fire department access routes, escape routes and delivery zones. Practice shows that even the presence of a parking lot sensor has a deterrent effect on parking violators. The continuous monitoring makes it possible to carry out targeted on-site checks and, if necessary, to call a towing service.

Parking sensors in practice: quick return on investment

Whether it is increased customer satisfaction because of free parking spaces in the shopping center, the needs-oriented use of traffic officers, unobstructed restricted areas or increased revenue through fines and penalties, the introduction of a parking sensor solution pays off. The Bosch parking sensor impresses with its easy installation, long battery life (up to 5 years) as well as the absence of regular maintenance and calibration. As a result, the costs over the entire service life of the parking sensor remain low and, above all, can be clearly calculated.

Scalable parking sensor solutions

Parking sensors provide communities, shopping centers, businesses and commercial parking lot operators the ability to quickly and safely identify parking violators. Since Bosch pursues an open approach right from the beginning, the parking sensor can be flexibly integrated into existing, as well as newly planned, infrastructures. In contrast to other parking sensor solutions, there are no subscription fees; the respective operator receives full control over the data, which can be processed and visualized using apps, for example. IoT integrator and Bosch partner Zenner also offers a demo kit containing ten parking sensors and all the necessary accessories. This makes it easy to assemble prototypes. Decision makers can thus convince themselves in real time of the versatility and performance of the Bosch parking sensors.
