A new average speed control system is now operational on the S8 highway between Zielonka and Wołomin, monitoring traffic towards Białystok.
New Average Speed Control System Launched
A new average speed control system has been launched on the S8 highway between the Zielonka and Wołomin junctions. This is the latest automated control point in the Mazovia region, overseeing a key route from the capital city towards Białystok.
The devices are operating on the Mazovian section of the expressway between the Wołomin and Zielonka junctions, monitoring driver behavior 24/7. This section is one of the most congested routes in the Warsaw agglomeration, connecting local traffic with transit towards northeastern Poland.
How the System Works
The new system calculates the average speed over the entire journey between the start and end of the controlled section, rather than measuring speed at a single point. CANARD explains that cameras automatically record the time of entry and exit of vehicles, as well as data such as location, date, time of measurement, section length, maximum permitted speed, and the lane the vehicle was traveling in.
Drivers are informed of the start of the measurement by appropriate road signs placed before the monitored section of the route.
Expansion Plans and Funding
The location between Zielonka and Wołomin was previously identified by GITD as one of three new average speed control systems planned on the S8 route towards Białystok. The others are planned for the Ostrowi Mazowiecka bypass and the section from near Kołaki to the Mężenin junction.
The project to expand the automated traffic monitoring system is funded under the National Reconstruction Plan.
National Rollout of Speed Cameras
CANARD data indicates that 43 new average speed control devices will be launched across the country in the current expansion phase, monitoring nearly 400 kilometers of expressways and highways. Upon completion of this phase, the center will have 114 such devices, controlling a total of over 670 kilometers of routes.
Locations were selected in cooperation with the General Directorate for National Roads and Highways and the Police – in areas where excessive speed poses a real threat to road safety.
Implications for Drivers
For drivers, this means maintaining the legal speed limit for the entire length of the section, and not just in front of the camera. The speed limit on expressways is generally 120 km/h for passenger cars and 80 km/h for trucks, unless signage indicates a lower limit.
