Approach for different types of speed limiting factors in memory and ahead

Various types of speed limits may influence driver behaviour, and in different ways. These are:

• Maximum vehicle speed.
• Speed limit from road type (e.g. 130km/h on freeways, 80km/h on rural roads).
• Fixed speed signs (e.g. 100km/h on a freeway).
• Dynamic speed signs (e.g. matrix on gantry).
• Various types of local limits (e.g. curvature, bumps, puddle).

For some of these, it is required to decelerate to an appropriate speed before a specific location, while for others a more relaxed approach is suitable. Behaviors for different speed types need to be possible, while classical car-following models (with a free term) need to be supported, resulting in a sensible most critical acceleration.
