Hello, the gap that is required between vehicles depends on the following vType parameters:
minGap, tau, decel SUMO is quite conservative, demanding that an inserted vehicle must be able to stop with a distance of minGap even if the predecessar starts braking with decel to a full stop when the inserted vehicle has a reaction time of tau to start braking itself. (even if this behavior is quite unlikely). As an additional problem vehicles are only inserted at full seconds if the gap after 2 seconds is a tiny bit to small a large gap (larger than needed) will be used after 3 seconds. You can avoid this by using a reduced value of --step-time or inserting at the next free position (attribute departPos="free") regards, Jakob If you run the numbers and discover that the regards, Jakob 2014-03-16 20:36 GMT+01:00 <[email protected]>: > Hi All, > > I'm trying to insert vehicles into a motorway scenario, and I realised > I'm getting a backlog where they aren't inserted at the requested > insertion time (from XML file).
