![]() by setting departLane="random" (or free or best) On multi-lane roads, make sure that all lanes are used for insertion i.e. ![]() The following remedies are generally recommended to improve insertion flow: the insertion location must be modified by any of the following methodsįorcing Insertion / Avoiding depart delay #.There are multiple ways to avoid this effect: This may cause artifacts in insertion spacing because at the default step-length of 1s is (usually) too short for vehicles to be inserted in successive steps on the same depart location.īy default, the next attempt happens 2 seconds after the first vehicle has departed and this gap may be much larger then mandated by the carFollowModel. Insertion attempts can only happen in every simulation step. The parameter Dialog for individual vehicles lists desired depart.Opening Vehicle statistics lists the number of insertion-backlogged.Using sumo-gui several options exist for showing If there are many edges with delayed insertion, the additional insertion attemps in every simulation step can slow down a simulation Investigating insertion delay # The default and one may switch to 1) using the option -eager-insert. In older version of sumo 1) was the default and oneĬould switch to 2) using the option -sloppy-insert Since version 0.18.0, variant 2) is In an uncongested networks these methods behave similar but in aĬongested network with lots of vehicles which cannot be inserted variantĢ) is much faster. Vehicles after one of the vehicles could not be inserted for every edge with vehicles to insert, abort trying to insert.try to insert every vehicle in every simulation step.There are two methods for inserting vehicles into the simulation: The option -max-depart-delay is used, vehicles are discarded if they could not be If there is insufficient space for inserting the vehicle at it'sĭesignated departure time, that vehicle is put into an insertion queueĪnd insertion is repeatedly attempted in subsequent simulation steps. The precise nature of insertion in regard to position, speed and departĪs well as on the current state of the road network. Inspected in sumo-gui via the vehicle parameter If a vehicle cannot be inserted due to any of the above reasons it's The vehicle must be able to brake for any scheduled stops along its.The vehicle must be able to brake for any upcoming non-prioritized.Any follower vehicles must be at a safe distance according to their.The vehicle must be at a safe distance to any leader vehicles.Not intersect with other vehicles (including their minGap The vehicle (from its rear to its front position + minGap) must.In order for a vehicle to be inserted into the road network, some Using the functions 'move to' or 'move to XY' they canĮven be forcefully inserted into the network. Once vehicles are loaded they can be accessed and manipulated via TraCI This is done toĬonserve memory when performing long simulations. Size of which can be configured with the option -route-steps. Instead, vehicles are loaded in chunks, the
