The crossing of vehicles is avoided by allowing all vehicles to merge into a stream around the rotary and then to diverge out to the desired radiating road.
That means the vehicular lane change behaviour was purely based on availability of longitudinal gaps on road and that vehicles had no preference or desired position on road.
As a result, the networking performance becomes more uniform, which is a desired characteristic for road safety applications.
Based on this result, we may terminate a query session after 15 QR messages have been received or the desired percentage of road segment coverage, say 95%%, has been reached.
"This new law will bring more desired results for the road safety in Cambodia only if the government will take more serious actions to enforce the law".
The system warnings should initiate the desired reaction by the road user without causing annoyance, which can occur in case of too frequent low risk warnings.
Pre-pilot tests have examined such a possibility, and though their results were positive, motorcyclists complained that such strips influenced and reduced their ability to follow the road as desired.
for acceleration on an open road, velocity, desired velocity, distance to front vehicle, desired dynamic distance to front vehicle, velocity difference, a safe time delay between vehicles, a comfortable braking value, a minimum distance between vehicles and finally an exponent which is adjusted in order to mimic real vehicular flow patterns.
In order to achieve a high performance, a high accuracy of the detection of the VRU and correct classification (R1) is needed, as well as an accurate prediction of the behaviour of the VRUs and their trajectories (R2), and as efficient warning strategies (R3) and efficient user interfaces (R4) to achieve the desired reaction of the road user.
For example, the desired location is on roads, in rivers, and so on.
