Rules to define Deceleration Points. Rule 1 states that any node with a traffic light is a DP. The other rules look at preferential streets, to define which streets have priority to allow for vehicle passage and are represented by “\(\prec\)” and “\(=\)” symbols. Rule 2 establishes that if a vehicle hits a node with a segment \(e_1\) with equal priority among the incident segments (equal to \(e_3\)), then this node gets classified as DP, i.e. \(e_1 = e_3\). Rule 3 states that a node will be DP, i.e. \(e_1 \prec e_2\) if the car reaches a node coming from a segment with lower preference \(e_1\) than the node used to continue \(e_2\).The mapping figures present examples for how rules define DP when the vehicle approaches an avenue, roundabout or street junctions. This figure was generated using the open source drawing software Inkscape (v1.2) and the Python open source library Folium (v0.14.0).
