My agent couldn't find route

[khzannat]

I am implementing a futuristic scenario of BRT network for Dhaka, Bangladesh. While I am running the scenario I am having an error saying that from one node agent could not find the way to my Public transport stop. I assumed the access mode for public transport stop would be default walking which I configured as teleported mode. Could you please help me to find the potential reason of having the error and what can be done to resolve the problem? I also checked in VIA that my PT brt network doesn't have any break. I have added the part of the error.

[kainagel]

Could you please attach the full logfile? Thanks ...

[khzannat]

logfileWarningsErrors.log logfile.log I have attached herewith the logfile with error and full logfile.

[jalal1]

I quickly looked to the logfileWarningsErrors.log and I see the following:

2021-10-18T16:08:15,628 WARN Dijkstra:304 No route was found from node 317601113 to node pt_33. Some possible reasons: 2021-10-18T16:08:15,629 WARN Dijkstra:305 Network is not connected. Run NetworkCleaner(). 2021-10-18T16:08:15,629 WARN Dijkstra:306 Network for considered mode does not even exist. Modes need to be entered for each link in network.xml. 2021-10-18T16:08:15,629 WARN Dijkstra:307 * Network for considered mode is not connected to starting or ending point of route. Setting insertingAccessEgressWalk to true may help.

This means you have some issues in the network.xml. Use NetworkCleaner() first, then you have to manage the modes in the network.xml

I don't remember the exact details, but you may check some examples in GitHub, to see how modes are added to network.xml.

[khzannat]

Thank you very much for your suggestion. I did the network cleanup but it removed my BRT network. I think I couldn't make a connection of BRT with the existing network because all BRT nodes are manually created (as it is a future scenario). I used the following code to create node and then created connection between each node. var startNode = network.getFactory().createNode(Id.createNodeId("pt_start"), new Coord(237243.491728,2656248.34032)); network.addNode(startNode); connections.add(createLink("pt_1L", startNode, stop1))

I could not find a way to start (startNode ) the BRT node from the exiting node without creating a node. As a result, startNode overlapped with the existing node. Instead of creating a new node is it possible to refer to a existing node (example node ID: 317601113) as startNode?

[kainagel]

I have to admit that I don't know the details enough here; it would be good if other people could come to the help how this is typically resolved. Here are some thoughts:

• I think (!!) that the network cleaner only checks if the network as a whole is connected; it does not check if it is connected for any given mode. Therefore, in a multi-modal network a route request may still fail, even after network cleaner ran successfully.
• You can re-use pre-existing nodes. You can attach an arbitrary number of links to them. You can even have multiple links between the same pair of nodes, e.g. one for bicycles and one for cars. Can you say what your technical problem was there?
• It should be possible to have a (say) car network and a brt network, and have them unconnected. I would run both of them separately through the network cleaner before merging them. And then NOT run network cleaner again.
• You will need "accessEgressRouting" switched on for this to work. I think that this is the default.

If nothing of this helps, it would be helpful to isolate the plan that is causing the problem. Unfortunately, the corresponding error message does not give the person ID. I will try to add this functionality into the code. Evidently this will not help with 13.0, but since Christian already recommended a newer version ...

[khzannat]

Dear Professor Nagel, Thank you for your detail reply. My existing network (assigned for car and other mode) is not the problem. I developed my base model (existing scenario) with the existing network and it is not causing the problem. The problem appeared after creating a BRT network on the existing network. I have attached herewith the code I used to built the BRT network (I had to code each stoppage manually as appropriate documentation for it wasn't available). With this network the error I attached before is happening. This BRT network is not connected with the other node/link of the existing network. I assumed by default each stoppage will be accessed by teleported mode walking.

NB: Since, I am new to java and matsim my codes are not as clean as you might expect.

[kainagel]

Hello, if we are talking about code, it would be far easier (and standard within the open source community) to have a pointer to a git repo. Would that be possible?

[khzannat]

Dear Professor, I have attached herewith the github link of my public repository: https://github.com/khzannat/matsim-example-project/blob/master/src/main/java/org/matsim/project/CreateBrt.java Also, my input file are publicly available: https://github.com/khzannat/matsim-example-project/tree/master/scenarios/Dhaka_input

[vsp-gleich]

Hello, I just double checked with the open Berlin model and the car and the pt links are not interconnected and it works there. I don't see any obvious issue while fast reading the CreateBrt code. So IMHO the issue is most likely that someone tries to route to a pt link with a mode that is not pt alhough the pt links should only be used by pt. Have you tried using accessEgressRouting e.g. by adding config.plansCalcRoute().setAccessEgressType(PlansCalcRouteConfigGroup.AccessEgressType.accessEgressModeToLink); in your run class (before loading the Scenario)? The default value is AccessEgressType.none most likely for some old tests or backward compatibility.

[khzannat]

Hi Thank you for your suggestion. I have already tried your given suggestion. https://github.com/khzannat/matsim-example-project/blob/master/src/main/java/org/matsim/project/RunMatsim2.java I have added here the link of my runmatsim class where I made the changes to resolve the error. It seems it's not working as well.

[vsp-gleich]

Hello, looking at your Run class I saw https://github.com/khzannat/matsim-example-project/blob/b9e03b47dfe78124e84832db20a224eff991628a/src/main/java/org/matsim/project/RunMatsim2.java#L121-L123 where you add multiple allowed modes to all links. This could cause a routing request from a car link to a "pt_XXXX" link, i.e. between those unconnected networks. Furthermore I see https://github.com/khzannat/matsim-example-project/blob/b9e03b47dfe78124e84832db20a224eff991628a/src/main/java/org/matsim/project/RunMatsim2.java#L117 which adds pt as a qsim main mode, whereas in the open berlin scenario pt is not added there. Could you try without those lines 117 and most of all 121-123?

[khzannat]

Hi, If I remove line 117 and lines 121-123. I encountered a different error (attached bellow). Also, if the setnetworkmode for BRT line is pt, why setMainModes is causing routing request from a car to pt link? Because, I thought using this line config.qsim().setMainModes(CollectionUtils.stringToSet( "car,cng,pt")), I allowed car, cng, pt on the network instead of teleportation and network is a multimodal netwok. java.lang.RuntimeException: Object is null; follow stack trace at org.matsim.core.gbl.Gbl.assertNotNull(Gbl.java:209) ~[matsim-14.0-2021w15-20210412.124250-1.jar:?] at org.matsim.facilities.FacilitiesUtils.decideOnLink(FacilitiesUtils.java:135) ~[matsim-14.0-2021w15-20210412.124250-1.jar:?] at org.matsim.core.router.NetworkRoutingInclAccessEgressModule.calcRoute(NetworkRoutingInclAccessEgressModule.java:132) ~[matsim-14.0-2021w15-20210412.124250-1.jar:?] at org.matsim.core.router.TripRouter.calcRoute(TripRouter.java:174) ~[matsim-14.0-2021w15-20210412.124250-1.jar:?] at org.matsim.core.router.PlanRouter.run(PlanRouter.java:94) ~[matsim-14.0-2021w15-20210412.124250-1.jar:?] at org.matsim.core.population.algorithms.PersonPrepareForSim.run(PersonPrepareForSim.java:220) ~[matsim-14.0-2021w15-20210412.124250-1.jar:?] at org.matsim.core.population.algorithms.ParallelPersonAlgorithmUtils$PersonAlgoThread.run(ParallelPersonAlgorithmUtils.java:145) ~[matsim-14.0-2021w15-20210412.124250-1.jar:?] at java.lang.Thread.run(Thread.java:832) [?:?] 2021-10-25T20:56:43,568 ERROR MatsimRuntimeModifications:75 Getting uncaught Exception in Thread main java.lang.RuntimeException: Exception while processing persons.

If you open up all links for mode car, the closest link to the destination activity might fall on a pt link which is not connected to the car network (and does not need to be connected to the car network). That causes exceptions when routing between unconnected parts of the network. The qsim main modes are for the qsim only (the queue simulation that moves vehicles around the network). Here it makes sense to enter all modes for which the passenger is the vehicle's driver. However, pt passenger agents are handled separately because they are not vehicles moving according to the queue model between links but rather passengers hopping on and off pt vehicles which are simulated separately with driver agents. The config default comment says " [comma-separated list] Defines which modes are congested modes. Technically, these are the modes that the departure handler of the netsimengine handles. Effective cell size, effective lane width, flow capacity factor, and storage capacity factor need to be set with diligence. Need to be vehicular modes to make sense." Similar theory is behind the planCalcScore networkModes " All the modes for which the router is supposed to generate network routes (like car) " so https://github.com/khzannat/matsim-example-project/blob/b9e03b47dfe78124e84832db20a224eff991628a/src/main/java/org/matsim/project/RunMatsim2.java#L73 should be deleted, too (unless you want to add mode "cng" as a network mode, but certainly not pt. I do not know what cng is). Besides it seems you forgot to add config.plansCalcRoute().addModeRoutingParams( pars3 ); in line 66). The new error message looks as if there is still some issue with which link has which allowed mode.

Hello, Thank you for your answer. cng is basically autorickshaw. It can be considered as non-app based ride-hailing service/taxi service but the speed is below car. It's specification is defined in vehicle.xml file. I kept line 74 as I want car and cng as network mode.

Hi, I checked out your github repository and tried to investigate. File paths were inconsistent, so I had to guess to make it run, please double check. I changed the activity types in plans2.xml in order to have them consistent with the activity types in your config.xml. For me it gives no errors when running with java openjdk-11. If you give me write access to your repository I can commit this to your repository.

[khzannat]

Hi Can you check with my 1pc sample input? it is added in Dhaka_input2. And, the config I am using for running BRT is also added there. https://github.com/khzannat/matsim-example-project/tree/master/scenarios/Dhaka_input2 The error I mentioned above is still there.

Sorry, the file paths are inconsistent again. I changed some paths to use Dhaka_input instead of Dhaka_input2 where network-with-pt.xml.gz and the transit schedule and vehicles files are missing, but you also refer to a vehicles.xml file that does not exist. Could you please add a version whose file paths work?

I am sorry for the inconsistency. You can use all the input from Dhaka_input2 for runmatsim2. Runmatsim1 and Dhaka_input1 were for the base scenario, which did not have any error.

Thank you! Now I get the following error message: 2021-11-08T17:15:32,496 WARN NetworkUtils:437 [nearestNode not found. Will probably crash eventually. Maybe run NetworkCleaner?

So it is an issue with the network.

You have defined the modes "car","bus","rickshaw","hh","cng","pt" as available modes for your agents. Which of those modes are supposed to be

• real network modes with private vehicles running over the network (e.g. car)?
• teleported modes independent from the network (e.g. walk)?
• teleported modes with the travel time as the routed travel time over the network, but without any vehicle actually being simulated in the mobsim ("freespeed factor")?
• real public transit?: You have bus and pt and mention brt in other places. Typically we have passenger mode pt and that's it. Having multiple separate public transit modes is much more complicated and I'm not sure this is what you want.

Before implementing the BRT I did the base model with this network and there were no issues with it. Among the modes: Real network mode is car and cng. Bus, hh are public transport but not structured in Dhaka (not possible to manually develop the pt network mode for both of them), therefore I marked them as teleported mode and just want to estimate the travel time as the routed travel time over the network, but without any vehicle actually being simulated in the mobsim. Rickshaw I also marked as teleported mode as rickshaw is restricted for some network. Since brt will be implemented very soon in Dhaka I wanted it as pt network mode not as teleported like bus and hh. As a result I will be able to see BRT's impact after the implementation.

Hi, I just pushed another branch:

• the freespeed factor modes need the setting freespeed factor in order to be recognised as such. TeleportedModeSpeed confusingly is only for beeline teleportation independent from the network.
• those freespeed factor modes have to be found on the network. So far the network only had links with either car or pt, but there was no cng, rickshaw, hh or bus link. This caused the last error message. I added those modes to all links allowed for "car" in your run class. If you want some links to be allowed for car but not for rickshaw I reccomend to set the allowed modes in the input network file instead.
• Since your agents refer to the brt system as passenger mode "pt" in their plans, the transit mode should be "pt"

On that branch it works for me. I hope it works for you now, too.

Hi Thank you very much, I have couple of queries about the way you resolved the issue: 1) Before I set average travel speed as setTeleportedModeSpeed (I assume I set them as teleported modes independent from the network). If I want bus, hh to include as teleported modes independent from the network my previous code would work? Right? But it didn't! What could be potential reason for that? 2) Now you coded as rickshaw, hh or bus will be teleported modes with the travel time as the routed travel time over the network. You included setTeleportedModeFreespeedLimit which was the average speed before. Are they same? What teleported setTeleportedModeFreespeedFactor actually doing? 3) Following your recommendation do you have any code example of setting the allowed modes in the input network file as I have converted the osm network to matsim network?

1. Before I set average travel speed as setTeleportedModeSpeed (I assume I set them as teleported modes independent from the network). If I want bus, hh to include as teleported modes independent from the network my previous code would work? Right? But it didn't! What could be potential reason for that?

You forgot about mode "cng" which was not contained in the allowed modes of any link (causing the no nearest node found error) but was supposed to be a network mode. In a previous version you added it to all links including pt links, but those were not connected to all other links giving the exception during routing. Now each mode to be routed over the network has at least one link where it is registered as allowed mode and all links allowed to a certain mode are (apparently) interconnected.

2. Now you coded as rickshaw, hh or bus will be teleported modes with the travel time as the routed travel time over the network. You included setTeleportedModeFreespeedLimit  which was the average speed before. Are they same? What teleported setTeleportedModeFreespeedFactor actually doing?

setTeleportedModeFreespeedFactor sets the travel time to a factor of the freespeed of the link. I added setTeleportedModeFreespeedLimit in order to limit to the speed you set before so the resulting travel times should be more similar to what you had before.

3. Following your recommendation do you have any code example of setting the allowed modes in the input network file as I have converted the osm network to matsim network?

There is code to read in networks from osm, but that usually does not set any modes besides car. The modes you added are very specific I doubt anyone has written an example. This is something you have to define dependent on what restrictions you want to model. E.g. if you want to prohibit cng or rickshaw from using fast roads (e.g. motorways) you can try with a for loop over all car links (like the one I implemented) and then if freespeed <= 70 / 3.6 add cng and rickshaw to allowed modes.

Thank you very much, it resolved the issue :)
