[sumo-user] route.add raises TraCIException(prefix[1], _RESULTS[prefix[2]], err)
Hello, I'm using Traci to assing dynamically routes to the vehichle which will be inserted on the network. However, sometimes (and I didn't find the pattern of this issue) the instruction route.add(routeId, [route]) raises TraCIException(prefix[1], _RESULTS[prefix[2]], err). I looked for any bug fix on Sumo Logs and also debug the code... without success. Maybe could be a SUMO issue. Follow the error: File "C:\Users\Pedro Matuck\Documents\GitHub\mestrado.sumo\speed_control\route_manager.py", line 142, in UpdateRoutes traci.route.add(str(newRouteId), newRoute) File "C:\Program Files (x86)\DLR\Sumo\tools\traci\_route.py", line 47, in add self._connection._sendExact() File "C:\Program Files (x86)\DLR\Sumo\tools\traci\connection.py", line 105, in _sendExact raise TraCIException(prefix[1], _RESULTS[prefix[2]], err) traci.exceptions.TraCIException: Could not add route. Error: tcpip::Socket::recvAndCheck @ recv: peer shutdown Quitting (on error). Thanks. -- *Pedro J.

[sumo-user] Loading Files
Hello, I'm using Traci to generate a .rou.xml file. However, it's generated based on number of nodes and edges which I get from GetIDList methods. To access the GetIDList, I need to start the simulation using .sumocfg file which reads a .rou.xml file. I need to create the rou.xml before load .sumocfg. It's possible to load the network file (to access the nodes and edges information) and after some instructions start the simulation with .sumocfg file? Thanks. -- *Pedro J.

Re: [sumo-user] Car routing
Jakob, Grateful with the support so far. :) these two parameters are enought to guarantee that all cars will have the reroute devices and the "edges choice" will be randomly? Another question... I didn't understand the parameter for weights.random-factor. What is the difference if I set '10' or '1000'?

[sumo-user] Indicators of traffic jam
Hi guys, Which indicators of traffic jam can I access using Traci? On Sumo-GUI, we have a panel (below right on screen), where is possible to check departed and arrived cars, avg. speed, etc. Looking on Traci API, not all of these patameters are accessible.

Re: [sumo-user] Car routing
Hi Michael, thank you for the return. I'll try to be more clear and specific. I'm working in a Machine Learning that should help the traffic flow. In summary, I configured a flow to start at some point of network and the cars should arrive at the destination. In the middle of that, I calculate the number of arrived cars and take an action after some fixed number of steps. What I'm trying to do, is (as you said before) influence the travel time changing the network aspects. For instance: At some point of simulation, if some lane is with high occupancy, I decrease it 'MaxSpeed' in order to make other lanes more interesting for the new inserted cars. Correct me if I missunderstood, but cars use dijkstra to calculate the fastest way, right? I just need to understand the conditions that affect the weight of lanes to train my ML in a simple scenario: it involves just single lanes, one type of cars and a grid network generated by 'netgenerate' (3x3 or 4x4 nodes). Thank you again. 2018-01-14 17:44 GMT-02:00 Michael Behrisch <o...@behrisch.de>: > Hi, > the short answer is it takes the fastest route based on the current > travel times in the network (this describes the edge part, the lane part > is handled by the lane changing algorithm).

[sumo-user] Computational cheapest way to use flow of vehicles
Hi guys, I need to run a simulation over a hundred of thousands steps. While the simulation is running, I need to keep one or more vehicles flows on the network. Looking network parameters, when the simulation reaches over 5000 vehicles loaded, the simulation steps starts to take a little bit longer, and each more loaded vehicles I get, more slow the simulation becomes. There's any way to use the flows without kiiling the simulation performance? I don't need to keep the cars instances, just to count how many of them reach in certain network location.

Re: [sumo-user] Retriving Vehicle Total Travel Time
Hello Jakob, thanks for the quickly answer. In fact I don't need to print the value, I just need to store it in a variable (On TraCI) in order to perform some calculations regarding to the reward function of my AI. Is there any variable that holds this value before print on console? So I can take the 'duration' value from there.

Hi, On my research, I need to calculate the mean travel time of my network. So far, I'm retrieving this information from tripinfo output. For every simulation, I need to perform an I/O operation. Then, I read and parse the xml, retrieving the information to calculate the average.
