Real time monitoring of traffic light settings
The province of Utrecht has made various data sources available in a dashboard for its own employees in operational traffic management. The dashboard provides operational traffic experts with real-time insight into the effect of a traffic installation on the street.
How are NDW data applied?
In the dashboard, the province of Utrecht also discloses the Floating Car Data that they purchase via NDW. This is data obtained from GPS positions of various devices such as navigation systems, mobile phones and tracking systems. NDW provides average travel times and speeds over segments (max. 50 meters) of the road network every minute. In addition to NDW data, other data is also applied in the dashboard, including Google waze data, data about planned and current roadworks, maps and parking data.
How does it work
The dashboard makes traffic congestion visible by comparing the current speed with the current maximum speed on a route. The amount of traffic in relation to the capacity of the road is also visible. We immediately see if a traffic installation is not functioning optimally. This may be because there are activities in the area, because an accident has occurred, a major event is taking place, or there is, for example, a lot of short-cut traffic. The functional manager can intervene immediately. The dashboard also helps us to make choices if, for example, several traffic installations have failed. Which installation do we repair first, because it disrupts traffic the most?
Why did the province develop the dashboard?
The dashboard provides operational traffic experts with real-time insight into the effect of a traffic installation on the street. With this insight they can take measures more quickly if congestion and traffic jams are likely to arise. They can also better manage the incident managers, because they know exactly where an incident is. Ultimately, this also contributes to a safe and liveable environment for all Utrecht residents. In short: do not sail blindly on technology, but look at the effect of technology on the street on traffic flow and thus on the satisfaction of the road user.
