Re: [sumo-user] Doubt about speed

[Jakob Erdmann <namdre.sumo@xxxxxxxxxxxxxx>]

Hello,

this sounds like there's a misunderstanding somewhere.
13.89m/s is the default edge speed in a sumo network so most likely the vehicle is still affected by an edge speed limit.

The maxSpeed value of the vType only defines an upper bound for vehicle speed. The speed limit of  the edges must be configure separately.

You can check the speed limit by right-clicking on the edge and opening its parameter dialog.

Regards,

Jakob

Hi guys,

I would like to know what is happening.
I'm doing a research to compare a time of a route using variableSpeedSign
against the own sumo control, and this is happening:

variableSpeedSign:
time 0 : <vehicle id="veiculo_1" ...  route="rota1" ... speed="0.00" ... />
time 1 : <vehicle id="veiculo_1" ...  route="rota1" ... speed="2.50" ... />
time 2 : <vehicle id="veiculo_1" ...  route="rota1" ... speed="5.00" ... />
time 3 : <vehicle id="veiculo_1" ...  route="rota1" ... speed="7.50" ... />
time 4 : <vehicle id="veiculo_1" ...  route="rota1" ... speed="10.00" ... />
time 5 : <vehicle id="veiculo_1" ...  route="rota1" ... speed="12.50" ... />
time 6 : <vehicle id="veiculo_1" ...  route="rota1" ... speed="15.00" ... />
time 7 : <vehicle id="veiculo_1" ...  route="rota1" ... speed="17.50" ... />
time 8 : <vehicle id="veiculo_1" ...  route="rota1" ... speed="20.00" ... />
time 9 : <vehicle id="veiculo_1" ...  route="rota1" ... speed="22.50" ... />
time 10 : <vehicle id="veiculo_1" ...  route="rota1" ... speed="23.33" ...
/>  <-- Max value

The sumo
time 0 : <vehicle id="veiculo_1" ...  route="rota1" ... speed="0.00" ... />
time 1 : <vehicle id="veiculo_1" ...  route="rota1" ... speed="2.50" ... />
time 2 : <vehicle id="veiculo_1" ...  route="rota1" ... speed="5.00" ... />
time 3 : <vehicle id="veiculo_1" ...  route="rota1" ... speed="7.50" ... />
time 4 : <vehicle id="veiculo_1" ...  route="rota1" ... speed="10.00" ... />
time 5 : <vehicle id="veiculo_1" ...  route="rota1" ... speed="12.50" ... />
time 6 : <vehicle id="veiculo_1" ...  route="rota1" ... speed="13.89" ... />
time 7 : <vehicle id="veiculo_1" ...  route="rota1" ... speed="13.89" ... />
time 8 : <vehicle id="veiculo_1" ...  route="rota1" ... speed="13.89" ... />
time 9 : <vehicle id="veiculo_1" ...  route="rota1" ... speed="13.89" ... />
time 10 : <vehicle id="veiculo_1" ...  route="rota1" ... speed="13.89" ...
/>

But, the maximum value for that street is 23.60. Why is this happening ?
The car doesn't reach the value which I would like.

On the route file:
<vType id="carro_1" accel="2.5" decel="3.0" length="2.0" maxSpeed="23.6045"
sigma="0"/>
<route id="rota1" edges="gneE0 gneE1 gneE2 gneE3 gneE61 gneE62"/>
<vehicle depart="0" id="veiculo_1" route="rota1" type="carro_1"/>

Best regards.
