Trajectory speed monitoring, or 'Trajectcontrole' in Dutch, is a sophisticated system designed to promote consistent speed limit adherence on motorways and other major roads. Unlike traditional speed cameras that measure speed at a single point, Trajectcontrole calculates your average speed over several kilometers. This method significantly enhances road safety in the Netherlands by encouraging drivers to maintain legal speeds throughout a monitored section, rather than just slowing down for a single camera.
Trajectcontrole
Trajectory speed monitoring, also known as average speed check (Trajectcontrole), is a system that calculates a vehicle's average speed over a specific road section.
Think 'TRAJECTory' as in 'travel over a long section'. It's about your speed over the whole journey, not just one spot.

You are driving on a Dutch motorway (A-road) that has signs indicating 'Trajectcontrole' is active over the next 10 kilometers. The speed limit is 100 km/h.
You must maintain an average speed of 100 km/h or less throughout the entire 10-kilometer stretch, ensuring consistent adherence to the speed limit.
Trajectcontrole calculates your average speed from the entry to the exit point. Even if you briefly exceed 100 km/h, your overall average must remain at or below the limit to avoid a fine, emphasizing the importance of continuous legal speed.
You are approaching the end of a long Trajectcontrole zone on a busy road. You notice other drivers speeding up as they see the exit cameras.
Continue to maintain the legal speed limit until you have fully exited the Trajectcontrole zone. Do not accelerate or copy unsafe driving behaviour.
Speeding up at the end of the zone, or at any point, will increase your average speed for the entire section. The system records your time over the full distance, so a last-minute burst of speed could still lead to a fine if your calculated average is too high. Maintaining a steady, legal speed is safest and ensures compliance.
You accidentally exceeded the speed limit for a short period while in a Trajectcontrole zone, but then immediately slowed down below the limit for a longer duration.
Continue to drive at or below the speed limit for the remainder of the Trajectcontrole section, aiming to lower your overall average speed as much as possible.
The system assesses your average speed over the entire segment. While a brief excess can contribute to a violation, consistently driving below the limit afterwards can help bring your overall average down, potentially avoiding a fine or reducing the severity of the infraction if the average remains above the limit. It's about the cumulative effect.
Learn about Trajectcontrole, the Dutch system that monitors your average speed over a road section. Essential for theory exams and safe driving.
In the Netherlands, Trajectcontrole systems are commonly deployed on highways and other critical road sections. When a vehicle enters a monitored zone, cameras record its license plate and the exact time. At the end of the monitored section, another set of cameras records the vehicle's license plate and the time it exits. Sophisticated software then calculates the average speed. If an infringement occurs, a photographic record is sent to a central processing unit, leading to a penalty. For vehicles that comply with the speed limit, the images are typically deleted to protect privacy.
Trajectcontrole is highly effective in improving road safety because it discourages the common practice of drivers briefly slowing down for a visible speed camera and then accelerating again. By enforcing continuous speed limit adherence over a distance, it promotes a smoother, more predictable traffic flow and significantly reduces aggressive driving behaviour and sudden braking. This consistent enforcement leads to fewer accidents, particularly serious ones, as demonstrated by various studies showing a reduction in fatalities and injuries on roads where Trajectcontrole is active.
The fundamental difference between Trajectcontrole and traditional spot speed cameras lies in their measurement method. Spot speed cameras (flitsers) measure instantaneous speed at one specific location. Drivers aware of these locations might momentarily reduce their speed to avoid a fine, only to resume speeding shortly after. Trajectcontrole, however, monitors your speed over an extended distance, making it impossible to evade by simply braking briefly. This ensures that drivers maintain a safe and legal speed throughout the entire monitored section, leading to more sustained behavioural changes and genuine safety improvements.
For the Dutch driving theory exam, it is crucial to understand how Trajectcontrole functions and its implications. Questions might test your knowledge of what constitutes an average speed check violation, how it differs from other speed enforcement methods, and its role in road safety. Remember that even short bursts of speed within a Trajectcontrole zone can result in a fine if your overall average speed for that section exceeds the limit. Consistent and lawful driving is key when passing through these monitored sections.

The primary purpose of Trajectcontrole (trajectory speed monitoring) is to enhance road safety by encouraging drivers to consistently adhere to the speed limit over an extended road section, rather than just slowing down for individual cameras. This leads to smoother traffic flow and fewer accidents, which is crucial for the Dutch driving theory exam.
Trajectcontrole calculates your average speed by recording your vehicle's license plate and timestamp at an entry point and then again at an exit point of a monitored section. The system then divides the known distance between these points by the time taken to travel, determining your average speed for that entire segment. This is important for understanding Dutch driving rules.
A regular speed camera measures your instantaneous speed at a single, fixed point. Trajectcontrole, on the other hand, calculates your average speed over a much longer stretch of road. This means that a brief moment of speeding within a Trajectcontrole zone can still result in a fine if your overall average speed exceeds the limit, a key aspect of safe driving practices.
No, you cannot avoid a Trajectcontrole fine by briefly braking. Since the system calculates your average speed over the entire monitored section, you must maintain the legal speed limit consistently throughout the trajectory. Sudden braking before a camera will not compensate for earlier speeding, reinforcing the need for continuous road safety understanding.
If your calculated average speed exceeds the legal limit within a Trajectcontrole zone, the system will process the infraction. A fine will then be issued and sent to the registered owner of the vehicle. Understanding these consequences is vital for preparing for your Dutch driving theory exam and for responsible driving.
