Hello François, The default Krauss model can handle this. If you configure your truck with decel="4.5" (or the same as all the other cars) minGap="0" tau="5.76" (10km/h = 2.778m/s, 2.778m/s * 5.76s = 16m) then you will get exactly 16m of extra gap for every 10km/h when following a leader car with the same speed.
In the latest development version you can easily test these numbers by calling traci.vehicle.getSecureGap The slow-to-start behavior can simply be calibrated by setting a lower accel value. regards, Jakob Am Fr., 17.
