Re: [sumo-user] How to simulate vehicles, given real veichle behaviours

you have several options:
1) generate individual attributes accel, decel, speedFactor for each vehicle
2) generate a parameter distribution fora accel, decel and speedFactor from the data (

3) pick one representative value for accel and decel and (mean) speedFactor and only use speedDev to model the speedFactor distribution. For this case I would recommend (note, that speedFactor is defined with reference to the speed limit):

accel = max acceleration  (use the 90th percentile to make this robust)
decel = max deceleration (use the 90th percentile to make this robust)
speedFactor = mean of (maximumSpeed/speedLimit for each vehicle)
speedDev = deviation of (maximumSpeed/speedLimit - speedFactor)

Hi all, I have a problem about defining vehicles in my simulation.
I have data about real vehicles such as instant speed and acceleration.
Then I calculated mean, deviation, maximum and minimum (for the speed) and
max and minimum acceleration for each vehicle.
Is there any way to simulate a vehicle having the same characteristics?

My only idea is to define a vehicle type with these atttributes:
accel = max acceleration
decel = min deceleration
speed factor = speed mean
speed dev = speed deviation

I know that the actual beaviour of a vehicle depends on other factors, such
as lane speed limit, traffic etc. But I would simulate into an ideal case
in which the data obtained with the simulation is similar to the real one
(in the same conditions).

Thank you all.
