Self-Propelled bus test between Haarlem and Schiphol

Yesterday, Monday 18 July, rode on the bus lane between Schiphol and Haarlem a largely self-propelled bus. During the test on this self-propelled bus reached speed 70 km/h. Bus talk to the traffic lights along the way and can thus adjust his driving. There was still a driver on board, which could intervene if necessary.

The Mercedes-Benz Future Bus has all sorts of sensors on Board that help him to stay in the lane. Of course, the bus gps, but there are also further radar and cameras, which include helping to recognize the color of traffic lights. During the test was one traffic light what is hidden behind a road sign, and this was alleviated because the bus via WiFi is connected to the traffic lights along the route. This communication between bus and nineteen Vialis traffic lights is laid out by the company. The CityPilot communication system allows the traffic light for hundreds of meters to the bus ‘ tells ‘ that on Red State.

Driving Self propellant bus

The bus lane which was used for the test, is to a large extent cut off from the normal lanes. Here and there comes the bus on the public highway, for example at intersections. During the test runs was a driver behind the wheel in order to monitor all systems and, if necessary, to intervene. The bus drove up to the speeds on the ground are allowed (50 – 70 km).

From about 300 m before the traffic light starts the communication. The bus reports that he is under way and the traffic light tells its current color to the bus. That way is easy to predict the color is like the bus at the light has arrived. The bus can do a request for green light and depending on traffic that request.

Restaurant style and relaxing environment

According to parent company Daimler, this communication ensure that the bus has a smooth driving style. That is not only beneficial for fuel consumption, but also for the comfort of the travelers and for safety, because suddenly brakes at a stop light is no longer needed.

The test was a cooperation between the German Daimler, the Ministry of Infrastructure and the environment, the province of North-Holland as road administration and owner of the bus lane, the municipalities of Haarlem and Haarlemmermeer and Vialis as a partner in traffic technology.

Test country Netherlands

The test with this first self-propelled bus fits well within the Netherlands’s ambition to walk from here as a test country for self-propelled units. So reason in april of this year, trucks from various corners of Europe in self-propelled trains (truck platooning) to Rotterdam. And this year also found the Grand Cooperative Driving Challenge place in our country.
