Part of Dutch Project: Brabant In-Car II
The aim of the experiment is to show the potential of cooperative systems in an environment as real as possible. We chose to demonstrate in this project an application which reduces the congestion problem on Dutch motorways. The application is especially meant to solve the ghost traffic jams. ‘Shockwaves’ and ‘harmonica-effects’ in traffic flows often lead to ghost traffic jams. These traffic jams are caused by sudden breaking or lane-changes and the reactions to this by traffic participants behind. Most of the time the cause of the traffic jam is unclear for road users.
Normally road users only anticipate on the vehicle immediately in front. Through communication with an in-car system the drivers have the ability to anticipate on the behaviour of the drivers several vehicles ahead. This possibility will improve the traffic flow and reduce the ‘harmonica-effect’. The road capacity will increase. To determine the effect of the communication between vehicles a large amount of vehicles is necessary. The experiments are performed on a highway consisting of multiple lanes. The effect is measured using camera’s situated along the highway.
In this project the drivers are supported by giving them an optimal speed advise. This optimal speed advise can be formulated for each car individually, depending on the local traffic status.
By using camera’s and floating car data we know exactly where, when and how our connect vehicles are driving, … including all other vehicles on this highway. We also use a real time tracking system at the intersection.

Details of Field Operational Test
Start date and duration of FOT execution
June 2012 – December 2012
A270 highway between Deurne and Helmond, the Nehterlands
To reduce traffic jams.
To drive efficiently
To improve safety of vulnerable road users (pedestrians, Cyclists).
Communication: 802.11p can be used as a local ad-hoc network which is very fast: 88% of the messages have a delay less then 2 s.
3G can be used as global network, it is not so fast: 36 % of the messages have a delay less then 2 s, 29% have a delay between 3 and 5 s, 34% have a delay more then 5 s.
Behaviour: Acceleration (and deceleration) is lower with advice at all intersections, A270 highway and Eindhoven trajectory.
Improved smoothness of traffic flow Reduction in CO2 emissions
Enthusiasm from volunteers /drivers. A lot of valuable feedback for future developments.
Good cooperation between partners
SW application worked good.
Variable performance of GPS signal has negative effect on performance of application
A lot of valuable data collected, more data would be desirable (reduce σ)
