Hey Harald, this is a good solution if you only consider the autobahn. The downside is that the speedFactor is also applied to all other streets with a mean speed of 45 km/h when 50 km/h are allowed is not realistic as the mean speed in reality is more likely 55 km/h. Maybe I can somehow overcome this issue through the combination of different vehicle types. Thanks for your help!
Did you take a look at the distribution of vehicle speeds? My experience is that you could have a huge amount of vehicles going at 140 km/h with the center of the distribution being not at 130 km/h. Make sure this isn’t the case! Best regards Simon From: [email protected] <[email protected]> On Behalf Of Harald Schaefer Sent: Dienstag, 21.

Greetings, Harald Am 21.07.20 um 09:08 schrieb Tripplanner Mumbai: Hello Harald, As per your definitions, speed limit of highway = 180 km/h, and vehicle's speedFactor=0.9 which means that the vehicle can run upto 160km/h on the highway (of course speedDev and sigma will affect it). Please clarify and/or rectify my views. thanks and regards, Dillip Rout On Tue, 21 Jul 2020 at 12:08, Harald Schaefer <[email protected]<mailto:[email protected]>> wrote: Hi Simon, in my own Autobahn-Scenario I want to run cars around 130 km/h.

I’m using exactly this for streets with a speed limit, but I’m targeting the special case of the German autobahn. As I understand it the simulation works as follows: If there are no speed limits, each vehicles drives it’s defined maxSpeed. The speedFactor is added to the maxSpeed, but if the driven speed exceeds the maxSpeed value, the speed is set back to it. Because of this there is no real speed distribution but just a los of cars driving at their maxSpeed.
