Oversize vehicle detection

The oversize vehicle detection system detects and excludes vehicles that are too tall or too wide for the road section on which it is installed. The system precisely detects the vehicle’s height and width up to 120 km/h.

The system consists of:

  • Devices for detecting oversized vehicles based on LiDAR technology
  • Cameras for recognizing the license plates of oversized vehicles
  • Control and management unit with GPRS communication, which processes data collected by LiDARs and cameras and sends them to the Oversize Vehicle Service Software
  • Oversized Vehicle Service receives information about oversize vehicles collected by a LiDAR device and a camera and automatically sends them to a Variable message sign.
  • VMS signs to display license plate numbers of oversized vehicles and messages about further actions the vehicle’s driver must take.
  • Control Center (SW-CC) – a software application that allows the user to see on the map the locations of all devices for detecting oversized vehicles, cameras and VMS in the system, to check whether all devices, cameras and VMS signs in the system work correctly, to download information about the number of oversized vehicles that passed through a given section in a certain period, as well as all data on oversized vehicles.

When the user logs in to the Control Center, he sees a map with the exact locations of all the devices in his oversized vehicle detection system, along with the OVD Workgroup icon to which those devices belong.

In the Control Center, the user can see:

  • Vehicle statistics – The system collects and stores vehicle data, including location, date and time, vehicle size classification, vehicle image, vehicle license plate number, and height and width of oversized vehicles. The user can view tabular and graphical information on the number of oversized vehicles that pass through a given section over a given period. This data can also be filtered by selecting a period from the calendar.
  • Device statuses (Maintenance) – The user has a tabular display of all devices, with information on whether each device is online and whether all its hardware components are functioning correctly, or whether there is a problem with its operation.
  • Notifications – every time an oversized vehicle is detected, the notification “oversize vehicle” is received; when one of the devices is malfunctioning, the notifications “does not work” or “does not communicate” are received. The user receives information via a pop-up window and/or an e-mail notification.
