Automatic generation and positionning of traffic lights at intersections.Pedestrians that automatically walk around their block, to add some life to our scenes.A Virtual Driver, which can drive any car on any road network, while being controlled with high level goals, such has вЂњkeep your laneвЂќ or вЂњturn left at the next intersectionвЂќ.With such description at hand, weвЂ™ve been able to implement some major features of our platform, that weвЂ™ll detail later in this blog. Having access to the complete road description empowers the scenario designer to easily control any actor within the scene.

If your scenario involves following a lead car, you want to be able to simply set the lead car to вЂњkeep its laneвЂќ, without having to manually describe the curve it has to follow. When youвЂ™re building your experiment, you create some situations which involve other actors, such as cars or pedestrians. However, roads are never uniform and straight, so we need to have access to the actual geometry of them to compute those values.ДЄnother reason is scenario creation. If the road is perfectly uniform and straight, computing those is simple. Some of that data includeДЄll of those values have one thing in common: they rely on the road geometry. As such, weвЂ™re interested in data that will be generated when subjects are driving. One answer lies in the reason why we use driving simulators: to run experiments.

Any road network in the world can be described in the OpenDRIVE format. This includes road geometries, marking, lanes, borders, etc. Initially developped through the PEGASUS project, OpenDRIVE was then transfered to ASAM, where its development continues.ДЄn OpenDRIVE file follows the XML standard and contains all relevant information describing a road network. But in driving simulators, we need much, much more information than that. Google Maps, OpenStreetMap), you might notice that you donвЂ™t get much description beyond вЂњthereвЂ™s a road hereвЂќ. If youвЂ™re familiar with traditional mapping tools (e.g. OpenDRIVE defines a file format for the precise description of road networks
