[sumo-user] parking area rerouter not triggering when parking area close to junction
|
Scenario:
1. Current (today) github build on 64bit windows 10
(& current win 10 release v1_2_0+0765-3423b2ab8c)
2. Parking area rerouter configured
3. Parking area close to junction (startPos="2.6")
4. The first vehicle reaching the junction after the parking area is full gets rerouted as expected
5. The next vehicle simply stops on the junction and waits for a space in the parking area.
Is this behaviour an expected artefact of the simulation?
Scenario can be demonstrated using the build test:
sumo\extended\rerouter\parking\congestion_alternatives :
If parking_c is set to startPos="2.601" or less then traffic is stopped once the parking area is full.
If this is set to startPos="2.6011" traffic flows normally. I have seen equivalent behaviour on other layouts with positions of 3.4/3.4011 but can't identify the layout difference causing this.
In trying to pin this down it appears to be related to the vehicle speed in the last step being set fractionally low such that the vehicle does not quite get to the end of the junction. (myState.myPos < myLane->getLength() stays true with vehicle stopped) I had to set debug output to 4 decimal places to clarify this.
Unfortunately I don't understand the code well enough to work out where the incorrect computation, (if that is what it is), is happening. Happy to continue looking if anyone can give me a pointer as to where I might look.
cheers
