First, the detector is applied to the input image and this will generate road candidates.
Figure 3 shows a part of the generated road network and a platoon of 10 vehicles.
A prototype of the ITPS has been validated in simulation using a small fleet of robot taxis with randomly generated road networks, background traffic load, and passenger requests.
In the evaluation of road roughness and its effects on vehicles response in terms of ride quality, loads induced on pavement, drivers' comfort, etc., it is very common to generate road profiles based on the equation provided by ISO 8608 standard, according to which it is possible to group road surface profiles into eight different classes.
Professor Stephen Glaister, director of the RAC Foundation, said: "Space is at a premium in London and we have to use imaginative ways of generating new road capacity to replace road space allocated for other improvements, while recognising the need to improve safety and cut emissions.
Unless sustained, coordinated action is generated in road safety, road traffic deaths are poised to rise from approximately 1.3 to 1.9 million a year by 2020 (Krug, 2012).
After generating the road surfaces profiles characterized by different damage degrees, the next phase of the numerical simulations focused on the determination of dynamic loads transmitted to the ground by the vehicle.
Map data are available from OpenStreetMap for most regions in great detail and can be imported in the same way as presented in "Generating a road network representation" section.
The road dataset was compiled and imported into ArcGIS software to generate a road network dataset.
For practical purposes, the QCM (Quarter Car Model, see Fig. 1) [19] is the vehicle model that can effectively be used to study the dynamic interaction between vehicle and road roughness profile, and therefore in the study of vibrations generated by road traffic.
