[sumo-user] Extremely High Values Returned by traci.edge.getTraveltime

[sumo-user] rerouteTraveltime Odd Behaviour
Hello, I’ve ran into an odd behaviour in regards to traci.vehicle.rerouteTraveltime(). Sometimes, the best time will produce a route with an absurdly long (as in it will be 100x more than expected kind of long) estimated travel time (using the current travel times of the edges in the route) - unusually, this is not actually the ‘best’ travel time possible, other routes are actually available which are a far better which aren’t picked up by rerouteTravelTime. Do you know why this may be? Have you come across this before? If so, is there a fix to this issue?

[sumo-user] Rerouting Question
Hi there, More of a generic question – when rerouting a vehicle with vehicle.rerouteTraveltime(), does the vehicle account for traffic as it currently stands or traffic that it estimates will be there once the vehicle reaches the point of congestion? E.g. say a vehicle has 2 possible paths it can lead down, path 1 is congested at the moment but by the time the vehicle reaches it the congestion should have cleared, path 2 is not congested whatsoever, however, by the time the vehicle reaches it the path will be fully congested. In this case the vehicle should take path 1 given these future conditions. Does SUMO do this automatically or only reroute based on the exact current road conditions? If it does, is there any documentation you know of regarding this?

[sumo-user] vehicle.setRoute() Changing Initial Edge
Hello, I’m currently attempting to set the route of a vehicle during runtime, however, currently setRoute() returns the error “raise TraCIException(prefix[1], _RESULTS[prefix[2]], err) // traci.exceptions.TraCIException: Route replacement failed”. After doing some debugging I believe the issue is that I am setting a route which does not begin with the edge in which the vehicle is currently occupying. For example, if I have a route which I know would work from the point of the simulation beginning, if I were to set that route after the vehicle had moved off that initial edge, I would receive the error. I’ve tried to do vehicle.changeTarget() with the last edge of the aforementioned route being the target in hopes that the route would be rebuilt with the first element in the route list being the current edge, however, the origin edge is still used. I have also tried to do a rerouting using rerouteTraveltime(), again with the hopes that the routes generated would be from the current position of the vehicle, but with similar results to the changeTarget() method. Is there any methods in order to reroute the vehicle with consideration of it’s current edge (where the route would be from that current edge to the same destination edge as defined in the routes.xml file)?

[sumo-user] Rerouting Multiple Vehicles
Hello, An observation I’ve had when rerouting many vehicles at once (going through a list of vehicles and rerouting them one after the other) is that the rerouting of the first vehicle seemingly takes by far the longest (sometimes being up to 10 seconds), whereas the other vehicles present in the lift are rerouted instantaneously without noticeable delay. This has been checked with debugging and regardless of any changes made to the code the first rerouting always takes a significant amount of time. Even when not iterating through vehicles and simply rerouting a single vehicle x amount of times (in a while loop), the first rerouting still takes the longest. Have you observed this? And if not, do you think this may be down to some type of hardware limitation?

[sumo-user] Vehicle.rerouteTravelTime() currentTravelTimes
Hello, I’m using Traci to interface with SUMO. I’m currently trying to reroute vehicles based on travel time, to do this I’ve decided to change the vehicle’s travel time for an edge using setAdaptedTraveltime() and then rerouting using vehicle.rerouteTravelTime(). I’ve noticed there’s been a few questions asked about this method, but I am still unsure what this really means; could you provide an explanation as to what exactly the difference between true and false is? Whenever I run it I find there is no difference whether this is True or False as the same route is always given. Furthermore, is there an easy way to remove all of the adaptedTraveltime’s for each of the edges (in the vehicle’s internal memory) such that all travel times reset to their global settings (edge.getTraveltime())? I’m aware there’s a begin and end to setAdaptedTraveltime(), the issue is that if the beginning is say the current time and the end is current time + 1, and at the same point you reroute based on travel time, you’d think that the vehicle would change route (as it has those settings loaded) when calling rerouteTraveltime(), but I’ve found that the vehicle only really reacts to this if the endTime is after the end of the route journey time. Is there any way to simply set a traveltime for the step you are taking so that you can compute an alternative route and have all of the settings turn back to the global once the next simulationStep takes place?

[sumo-user] Code Completion with Traci
Hello, Currently using Traci to interface with SUMO. One small problem I have ran into is code completion (I’m using Pycharm), for example if I’m inserting ‘traci.’, instances such as ‘edge’ do not appear in the list. Further when typing ‘traci.edge.’, functions associated to that do not show up, e.g. getIDList(). When I insert ‘traci.’ I get some suggestions, e.g. ‘traci._edge.EdgeDomain’, but from my understanding these aren’t meant to be used in code but you should use the instantiated version – in this case ‘traci.edge’. I’m unsure if this is the correct thinking or not as I am new to Python, having switched from using TraaS due to some limited functionality. Is there something I need to add/settings to change to have some kind of code completion in Pycharm when inserting commands such as ‘traci.edge.’, or is this an issue with the dynamic typing of Python?

Interestingly, when passing one correct parameter, e.g. ‘python randomTrips.py -n map.net.xml --trip-attributes="departLane=\”best\”” -r routes.xml’, the same error “Error: attribute value expected” occurs, whereas with multiple parameters for –trip-attributes produces no error (and subsequently no route file).

[sumo-user] (SUMO) TraaS Dynamic Routing & Incomplete Routes
Hello,
I'm unsure on how to dynamically assign routes to vehicles (with each vehicle
having a route which is unique to them) depending on certain conditions (i.e.
traffic jams, congestion). I'm using TraaS to interface with SUMO and need to
react to certain conditions and dynamically assign routes to particular
vehicles depending on their location relative to the road condition.
I've read about automatic re-routing here:
http://sumo.dlr.de/wiki/Demand/Automatic_Routing, however I'm unsure how to
activate this (if it's not done by default), or if this is even the correct
solution.
So far I've been able to assign a route in TraaS, but I can't seem to use
DUAROUTER during runtime to be able to generate the route from point A to C
without defining the intermediate edges, C (trip -> route). From my
understanding a trip is a start and end destination, whereas a route is this
with the addition of all of the intermediate edges passed through.
SumoStringList listExample = new SumoStringList();
ArrayList edgeList = new ArrayList<>();
edgeList.add("edge1");
edgeList.add("edge3");
listExample.addAll(edgeList);
conn.do_job_set(Route.add("test", listExample));
When ran (without edge2 being included in the edgeList) I get the error Vehicle
'testVehicle' has no valid route. No connection between edge 'edge1' and edge
'edge3'., which is resolved upon including edge2.
Is it possible to convert trips -> routes during runtime? Is there a way to
call DUAROUTER (or another tool) during runtime in TraaS?
Many thanks

Hello,
I’m currently using TraaS to interface with SUMO. I am attempting to reroute a
vehicle and hope to make it change path by setting an effort to an edge (I
believe this is the equivalent of setting a ‘weight’ to that edge), this effort
is calculated from the congestion + other metrics.

I receive the errors “Unexpected command and status IDs match: expected 202,
got 196” given by Traci (TraaS), and “Error: Answered with error to command
0xc4: Setting effort requires a compound object.” given by the SUMO client.
Is there anything more to this? Is the syntax wrong?
2. When setting an effort for a vehicle Vehicle.setEffort(), is this simply an
effort given to an edge for a period of time exclusive to this vehicle?

Hello,
- automatic routing is suitable if you just want vehicles to react to changing
road conditions (congestion). This causes them to periodically check if there
is a better route and then change the route but keep the original destination
- if you need more influence on the timing or individual routing preferences
you can call traci.vehicle.rerouteTravelTime
- if you need to change the destination you can call traci.vehicle.changeTarget
- for intermediate goals that must be visited you can define 'via' edge using
traci.vehicle.setVia
- if you want to compute fastest routes without affecting a vehicle you can
call simulation.findRoute
