Re: [sumo-user] Car vs Bus traffic

[Radha Reddy <radha.reddy.ipp@xxxxxxxxx>]

Hello Jakob,

SOrry initially I sent a wrong Cars-only scenario (different TLC program), but I have used the correct program only (attached) to compare with the Bus-cars scenario. As I mentioned in the previous email, in Cars-only scenarios ~1320veh/h are serviced while in Bus-cars scenarios it's 1440veh/h.

Please check the attachment for the correct version of the Cars-only scenario.

Sorry for sending different TLC plans. I have updated both of them being unique, but the results are the same.

The Cars-only scenario served 1320veh/h while in Bus-cars scenario it was 1440veh/h. A small change won't increase that much right, even if it is only Krauss CFM. There's something we are missing.

- Your two scenarios are using different traffic light plans

- Your busses are driving with the Krauss carFollowModel which makes better use of the defined maximum acceleration

Yes Jakob, 5 times with different random seeds. The average of 5 results show that the intersection throughput of mixed cars and buses is higher than the cars only scenario.

I do not understand why this happened.

Did you try running your scenarios multiple times with different seeds and averaging the results to check whether this is just random noise?

Hello SUMO Community,

I was analyzing the Intersection Throughput for an hour in two scenarios for 30KMPH: 1. only cars (100%), and 2. cars (99%) with Buses (1%).

Surprisingly, Scenario 2 has higher throughput values than Scenario 1, I do not understand why. When the length of some vehicles increased (i.e., Bus), it would be expected to reduce the performance right.

Will you please provide some insights why it is happening?

Regards

Radha
