Re: [sumo-user] Bidirectional lane and collision for overlapped edges

2020-09-28 Thread Richter Gerald
Hi Theodore, regarding the use of opposite lane overtaking, I can say that it is possible to declare a lane as the neighbor from one side, but not from the other. So asymmetric overtaking relations or lane dedication to one direction should be possible to implement. You probably need 3 edge

Re: [sumo-user] Potential danger in not using minGap

2020-09-28 Thread Jakob Erdmann
It depends on the car-follow model. The Krauss model treats the minGap as inviolable, hence setting it to 0 does not lead to crashing as long as tau > action-step-length. The downside would be that the cars are extremely close when in a standing queue (because the tau value only affects moving vehi

Emission output ( https://sumo.dlr.de/docs/Simulation/Output/EmissionOutput.html) givesmg/s for most pollutants but ml/s for fuel. Also, the values are always per-second so you need to multiply the values with you step-length to get per-step data. Am Di., 29. Sept. 2020 um 07:32 Uhr schrieb Jakob

The best way is to define a joint traffic light controller at both ends of the bidirectional section with layout="alternateOneWay". It will ensure that only one direction has access at a time. See https://sumo.dlr.de/docs/Simulation/Traffic_Lights.html#controlling_multiple_junctions_with_the_same_c

[sumo-user] Potential danger in not using minGap

2020-09-28 Thread Bae, Jong In
Hello, Would there be any potential danger in not using minGap (set it to 0) and increasing tau to like 1.8s or 2s instead? I assume that using the tau value greater than 1 should also give the follower vehicle enough room to brake without crashing. Basically, I'm curious if larger tau values ca

Emission output gives ml/s If you are using the default step-length of 1s you can simply sum the values to get the total. Otherwise you need to scale with step length. However, if you just need the total fuel consumption per vehicle, you can also use tripinfo-output with device.emissions: https://s
