Re: [sumo-user] SUMO Simulation: Vehicle Count Discrepancy

[Simon Michael <simongeb145@xxxxxxxxx>]

Thank you for your feedback, Mirko. Just I need to insert all the vehicles in the simulation to create congestion. 

I have set the departSpeed to 10 m/s and the traffic volume to 2400 vehicles per hour, but only 1400 vehicles were simulated. 

Do you have any suggestions on how to create congestion, please?

Kind Regards

Hi Simon,

 

It may be that not all vehicles could be inserted. The volume this is close to what is considered the capacity of a single lane (with default parameters). The capacity can be reached only under certain conditions, one being speed. If you insert the vehicles with speed v=0, they need time to accelerate which makes you lose capacity. Define the departSpeed attribute of your flow to change this.

 

Best regards

Mirko

Hello Everyone,
I am working on a SUMO simulation with one lane and a traffic flow rate of 1800 Veh/hr. The simulation duration is one hour (3600 seconds) and I generated FCD output. However, the number of vehicles simulated is less than the traffic flow. Only 1200 vehicles were simulated. Can anyone help me with this issue, please? I have attached my cfg file. Thanks
