HGV Parking

DYNAMIC EVALUATION AND DISPLAY OF FREE PARKING SPACES FOR HEAVY GOODS VEHICLES

Until 2025, goods traffic is expected to increase by more than 80 %, which will largely take place on the federal motorway network. Together with long-distance goods transports grows the demand for suited parking spaces for heavy goods vehicles (HGV) directly at or close to motorways.

With approx. 28,500 parking spaces for heavy goods vehicles at motorway service stations and just under 19,000 spaces at off-motorway rest areas, there is a deficit of nearly 15,000 parking spaces (ADAC 2009/2010). Accident statistics show that this often has fatal consequences. A significant number of accidents on motorways are caused by overtired truck drivers and accidents at service stations due to blocked access roads increase. Existing parking space for HGV must be managed in such way that it can be efficiently utilized. At the same time, the drivers must be able to plan their routes and compulsory breaks and to find parking space without tedious searching.

Creating, controlling and displaying HGV parking space is an investment in the safety of all road users. With competitive concepts, SWARCO TRAFFIC SYSTEMS makes its contribution to implement the future technology of HGV management.

Depending on the requirements, different methods and technologies are used to evaluate HGV parking spaces.

Single space method - Monitoring individual parking spaces:

  • Magnetic field sensors
  • Video technology
  • Inductive loops

Difference method - Counting entering and leaving vehicles:

  • Inductive loops
  • Radar detector
  • Ground radar sensor
  • Magnetic field sensors
  • Video technology

Tracking method - tracking individual vehicles:

  • ALPR - Automatic license plate recognition (in combination with other sensor technologies)

Other methods:

  • Laser scanner
  • Ultrasonic sensor
  • Microwave sensor
  • Piezo axle sensor
  • Passive infrared sensor

Dynamic display of parking spaces for HGV, motorway A5 Hartheim – Weil am Rhein, Baden-Wuerttemberg

In this pilot project on motorway A5 between Hartheim and Weil am Rhein in driving direction Basel, Switzerland, five rest areas were equipped with a parking information system for heavy goods vehicles. Free parking spaces are evaluated by balancing the entering and leaving HGV. They are detected by means of magnetic field sensors in the road, which wirelessly communicate with an access point. An outstation processes the data and transmits them wirelessly (e.g. GPRS) or via landline to a sign display in LED technology. In another step, the outstations on the rest areas will be connected with the traffic computer via fiber optic cable. This allows the HGV drivers or forwarding agents to search via internet for parking spaces at the connected rest areas.

Telematic control for HGV parking, motorway A2 rest areas Börde and Krähenberge, Saxony-Anhalt

In these pilot projects on motorway A2 in Saxony-Anhalt, telematic control for HGV parking at service and rest areas with different detection methods is being tested.

At the service area Börde, the occupancy of HGV parking spaces is determined by means of intelligent loops. Objective is to reliably determine the actual occupancy of the parking spaces and to neglect those vehicles leaving the parking area without actually parking. Nine detection points with inductive loops in the lanes determine the occupancy rate of the parking spaces. The passing curves are evaluated by means of a special algorithm. Balancing the entering and leaving vehicles, free spaces are evaluated. The information ist then forwarded to the display sign in LED technology. Two video cameras are used for traffic monitoring and control.

The rest area Krähenberge is equipped with a system based on video technology. The system consists of eight video cameras, each determining the occupancy of five HGV parking spaces by detecting individual vehicles. The results are merged and the number of free parking spaces is displayed via LED-sign located beside the motorway. A video camera with pan-tilt-zoom function is used to monitor the occupancy and to visually correct the numbers, if necessary.

Dynamic display of available HGV parking spaces, motorway A1 rest area Buddikate West, Schleswig-Holstein

In order to solve the capacity problems, the rest area is equipped with a system determining free HGV parking spaces by means of difference measurements and the according dynamic signs to display free parking spaces. The system uses ground radar sensors and a central software with federally regulated data distribution acc. to German TLS / MARZ incl. fiber optic rail switch, software modules for the control, operation, maintainance and video monitoring. The rest area is connected with the control center in Neumünster where the operating station is located.

Display of HGV parking spaces, motorway A8 service and rest area Aichen, Baden-Wuerttemberg

The rest area Aichen has a seperate area for 54 heavy goods vehicles plus another nine parking spaces for busses and caravans. In the entrance and exit to and from the parking area, each vehicle is registrated by means of wirelessly working magnetic field sensors. From the difference between entering and leaving vehicles the number of free spaces is evaluated. In the first step of the project, the available parking spaces were displayed at a dynamic sign located within the service station. In the second step, an additional sign display was installed directly at the motorway approx. 400 m in front of the ramp to the service station. In regular operation mode, the system works completely automatic.
