Thanks Jacob. It's working now.

 Hi Jacob,

 Could you please tell me what is the default speed mode value used in
 Sumo, where the vehicles speed up if the lane is free? I thought it's 31.
 In my simulation, I first made the speed mode as 0 that makes all checks
 off. In next simulation step when I'm resetting the speed mode in 31, the
 vehicles are moving at constant speed. They are not accelerating even if
 the lane is empty. I'm working in traci-matlab.

 Thanks in advance,
 Santa

Hello,
command traci.vehicle.setSpeed sets the new desired speed indefinitely. In
order to go back to normal behavior the command setSpeed(vehID, -1) must be
sent.

Re: [sumo-user] How to get a person's position with more precision

[Jakob Erdmann via sumo-user]

If you run your simulation with option --step-length 0.1 then time
resolution is 0.1 seconds rather than 1s so you have more precision.

Jakob

[sumo-user] How to get a person's position with more precision

[Sara el hamdani via sumo-user]

Dear sumo users

Can I change deltaT or have more precision on the position of a person
using TraCI?

I am trying to get a person to stop when they reach the line between lanes
while crossing, and to do this the only way I found is by getting their
lanePosition. but between simulation steps my pedestrian passes the point
at wich I want to him to stop.

I would like to thank Jakob for answering my previous question.
