Hello, adjusting priority in the net.xml file will do no good as the right-of-way logic of the intersection (which takes priority into account) is already fixed at that point. You need to rebuild the network from plain.xml files to change the right of way logic. However, there is currently no junction type which enforces zipper-merge. In reality vehicles on the ramp must yield to vehicles on the autoroute (priority). If you change this to right_before_left, the ramp would get priority. You could allway_stop to make vehicles drive in an alternating pattern but this would force vehicles to stop even if no other vehicles are present. You could set up a traffic light to achieve alternating traffic but this would also give unrealistic results whenever one of the streams has no traffic (you would have to switch it on/off depending on the level of traffic). A solution might be a new junction type allway_yield which works like allway_stop but without the need to stop. However, even this would force vehicles on the autoroute to slow down even if no traffic on the ramp is present.
Do you know of any kind of traffic sign that enforces merging at on-ramps in alternating fashion? Is the type of behavior you wish to model something that already occurs in reality or something that you would like to experiment with? regards, Jakob 2014-04-15 16:01 GMT+02:00 Thierry <[email protected]>: > Hello all, > > I am trying to simulating how vehicles on the ramps enter the autoroute, > only to find that the vehicles on the ramp would stop before entering the > autoroute in order to avoid a collision. > I thought it might because the priority of the ramp is lower than the one > of the autoroute.
