Assigning Buses to Routes

[gev...@gmail.com]

I was told that there is an auto-assigner module in TheTransitClock that will attempt to assign vehicles to blocks/routes/trips/bus lines based on GPS alone. 

I love that! Where I can read on the assigning bus to the line manually?

1:01 PM

Where can I read about this assignation of bus->lineNumber->route and what happens if two three bus lines are going with the same street but bus has changed the line number and serving now another line but is located on the same street?

Best regards

Hi Gevork,

There is no documentation that I know of.

This post has some detail.

https://groups.google.com/forum/?hl=en#!searchin/transitime/assign%7Csort:date/transitime/w_JZkt3sUVI/6UAkssvoDwAJ

To turn it on you use the configuration parameter transitclock.autoBlockAssigner.autoAssignerEnabled. 

More details and config parameters can be found in the java class. org.transitclock.core.autoAssigner.AutoBlockAssigner.

Cheers,

Sean.

Hi Gevork,

I think you may need to ask permission to join the old transitime mailing list. https://groups.google.com/forum/?hl=en#!forum/transitime

Hi Gevork,

We've used the AutoBlockAssigner module with a couple of different fleets. I need to write up a Wiki page for it on TheTransitClock's github, but in the meantime here is some information. I see you've had some success with getting TheTransitClock up and running from your other thread, so hopefully this will be enough to get you started.

1. Enable the module by setting transitclock.autoBlockAssigner.autoAssignerEnabled to true
2. Enable and configure an AVL module by adding the module to transitclock.modules.optionalModulesList (e.g. org.transitclock.avl.GtfsRealtimeModule). There are a number of existing AVL modules here: https://github.com/TheTransitClock/transitime/tree/develop/transitclock/src/main/java/org/transitclock/avl 
3. Alternatively, if you have data that doesn't work out of the box with one of the AVL modules, you can add a new one.
4. Be prepared to run a lot of tests and tweak a lot of parameters to get good results! Take a look at the descriptions of the config params in AutoBlockAssigner.java, MatchProcessor.java, TemporalMatcher.java, and SpatialMatcher.java. Use the webapp to view the active blocks (Reports > Active Blocks or /web/status/activeBlocks.jsp?a=[agencyid]).

The more information you have available for vehicles, the better. The less information you have, the less likely it is that all vehicles will be successfully matched with blocks. In order of preference:

1. Real-time trip assignments, with the trip corresponding to the GTFS trip_id
2. Real-time block assignments, with the block corresponding to the GTFS block_id (requires block_id in trips.txt)
3. Real-time route assignments, with the route corresponding to the GTFS route_id
4. Real-time location, speed and heading
5. Real-time location only

Also note, if your GTFS static data doesn't have block_ids, TheTransitClock will create a single block for each trip.

Cheers,

Nathan

Hi Nathan,

what a surprise that you wrote back :) Couple of days back I have used your GTFS validator, and saw you on the main page of OmniModal.io :) 

I have currently following issues that I scratch my head to solve 

1) TransitClock API is not working   

http://116.203.215.167:8080/api/v1/key/aca5c746/agency/tampa/command/agencyGroup   

The problem is in ticket #107 

https://github.com/TheTransitClock/transitime/issues/107   

I hope this will solve soon. 

2) Yes, indeed you are right. I have managed to create a docker installation script of multi agency setup   which was described in the Wiki. 

https://github.com/gelinger777/transitclockDocker   

3)  The problem 

Our initial setup is quite simple .   1 agency with 6 stops on each direction  with 7 buses . But still the problem is that it's 

So the second problem I have is following.  We don't have complicated AVL system. We will install tomorrow GPS trackers on each bus and will connect it to Traccar. 

I want traccar to give positions of the buses each n seconds ( by the way could you suggest the  optimal number of this number? )  to the TransitClock and then the TransitClock would show the  estimation of the arrivals . 

I have already saw that there is a module for that 

https://github.com/TheTransitClock/transitime/blob/develop/transitclockTraccarClient/src/main/java/TheTransitClock/transitclockTraccar/GetPositions.java

But if we look at code, it just takes the positions and makes System.

api.setApiClient(client);
	try {
	User user=api.sessionPost(email, password);
	List<Position> results = api.positionsGet(null, null, null, user.getId());
	for(Position result:results)
	{
	System.out.println(result);
	}
	} catch (ApiException e) {
	e.printStackTrace();
	}

Is this a working module at all?????

Sorry but my backrgound is not JAVA and I am a bit confused. What would you suggest to do exactly with the Traccar? 

Best regards

Gevork

Hi Gevork,

Oh, nice! Pleased to meet you.

You need to look at TraccarAVLModule: 

https://github.com/TheTransitClock/transitime/blob/develop/transitclock/src/main/java/org/transitclock/custom/traccar/TraccarAVLModule.java

Another option is using Traccar with Barefoot for better map matching (may or may not be needed depending on the quality of your GPS fixes): 

https://github.com/TheTransitClock/transitime/blob/develop/transitclock/src/main/java/org/transitclock/custom/traccar/TraccarBarefootAVLModule.java

https://github.com/TheTransitClock/transitime/blob/develop/transitclock/src/main/java/org/transitclock/custom/barefoot/BarefootAVLModule.java

The poll rate is set by transitclock.avl.feedPollingRateSecs. We recommend updates of at least every 30 seconds; ideally 10 seconds or less.

Regards,

Nathan

Nathan, thanks . Sorry  as I am not a person with Java background, I need to ask this (please bear a bit with me) . 

So in the  agency.properties file 

which was published here 

https://github.com/TheTransitClock/transitime/wiki/Multi-Agency-Configuration

# This is a similar configuration used by the Quick Start example (Intercity)
transitclock.core.agencyId=tampa
transitclock.db.dbUserName=DatabaseUsername
transitclock.db.dbPassword=DatabasePassword
transitclock.db.dbName=agency-tampa
transitclock.db.dbHost=0.0.0.0
transitclock.db.dbType=postgresql
transitclock.avl.gtfsRealtimeFeedURI=http://api.tampa.onebusaway.org:8088/vehicle-positions
transitclock.hibernate.connection.url=jdbc:postgresql://0.0.0.0:5432/agency-tampa
transitclock.hibernate.configFile=hibernate.cfg.xml
transitclock.modules.optionalModulesList=org.transitclock.avl.GtfsRealtimeModule
transitclock.web.mapTileUrl=https://tile.openstreetmap.org/{z}/{x}/{y}.png
transitclock.web.mapTileCopyright=OpenStreetMap
transitclock.rmi.secondaryRmiPort=0

transitclock.modules.optionalModulesList=org.transitclock.avl.TraccarAVLModule 

or 

transitclock.modules.optionalModulesList=org.transitclock.avl.TraccarBarefootAVLModule

Right?   

and then how I pass the transitclock.avl.traccar.email?

I put in the same file as next line?

so it will be 

transitclock.modules.optionalModulesList=org.transitclock.avl.GtfsRealtimeModule

transitclock.avl.traccar.email=email

transitclock.avl.traccar.password=password

transitclock.avl.traccar.baseurl = http://traccarhost

right?  

When we speak about polling, I imagine that we have two values 

1) GPS Tracker sending the position to traccar  ( I plan to put it like 4sec) 

2)transitclock requests the traccar on positions (would 10sec be ok? ) 

for the initial pilot project where you have one agency, 1 route 6 stops and 7 buses, do you think a vps with 2 vcpus and 8gb ram is enough? 

Best regards

Hi Gevork,

In this case, the value is `org.transitclock.custom.traccar.TraccarAVLModule`. The pattern is [package].[class], whose values you'll see towards the top of each file.

And yes, you can put all of your config values in that same .properties file, as you've typed out.

For polling, that's correct, those two values both influence the latency and refresh rate of the data. Those values sound good to start with.

Those server specs are more than enough - we're using a similar VPS for a fleet of ~300 vehicles and 75 routes.

Regards,

Nathan

Last questions , I promise. 

Most of the "complicated" thing that still my mind could not digest. 

We have a GTFS schedule of buses just out of air, because there is no schedule. Buses start on some point early morning from one side, they drive , turn and drive back , and then again.  Does TransitClock face that? 

Best regards

Gevork

TheTransitClock needs something to measure the real-time data against. That can either be a schedule-based GTFS, or a frequency based GTFS (I.e. frequencies.txt). In either case the drivers will need to be adhering to something - either the schedule itself, or the headways between trips. 

There is different configuration for frequency based prediction which I haven’t gotten deep into yet, so I can’t provide much guidance there.

Hi Gevork,

These parameters are not set to point to your Traccar server. You are getting a 404 which is a not found exception for the baseurl you configured.

Cheers,

Sean.

transitclock.avl.traccar.password=MYPASSHERE
transitclock.avl.traccar.baseurl=http://TRACCARIP/api/

But with the same Login/Password  and Link combination I am connecting from the Laravel perfectly. 

Do you think it's only a problem with the login/password/url values?

Hi Gevork,

"Caused by: io.swagger.client.ApiException: HTTP 404 Not Found - NotFoundException (...)"

This tells me it cannot see the baseurl.

[Gevork Grigorian]

http://tracker.opentransport.am/api/    if its just opened like that , it usually gives also 404. 

What is the right way to setup this baseUrl 

transitclock.avl.traccar.baseurl=http://tracker.opentransport.am 

or 

transitclock.avl.traccar.baseurl=http://tracker.opentransport.am/api 

????

Because the url is there.... maybe variable name is wrong? or the format ...

When I have set the api baseurl like this 

transitclock.avl.traccar.baseurl=http://tracker.opentransport.am/api

it went throught. Seems the problem was the ending slash...

But still transitime dont see the vehicles. How I can run GetPositions.java file?

<avl> looks like this 

   <avl>
        <!-- URL for GTFS realtime vechicle location stream. Changed name in versions do use both for the moment. -->
        <gtfsRealtimeFeedURI>GTFSRTVEHICLEPOSITIONS</gtfsRealtimeFeedURI>
                <url>GTFSRTVEHICLEPOSITIONS</url>
                <!--  These are the values used for Irish Rail. -->
         <minLongitude>43.417969</minLongitude>
        <maxLongitude>47.010498</maxLongitude>
        <minLatitude>38.788345</minLatitude>
        <maxLatitude>41.219986</maxLatitude>

        <feedPollingRateSecs>30</feedPollingRateSecs>

    </avl>

should I remove gtfsRealtimeFeedURI ? Or maybe need to setup something else?

You will need to look in TheTransitClock log files to see what is happening. In particular, files called core.log and avl.log.

Seems AUTH problem, but why .... ??? 

I am already losing a hope...

It seems API has changed 

And extra header is needed. 

I have downloaded the latest Swagger file and made maven clean and maven install -DskipTests and copied over Jar files but seems it did not work ....

Can It be that I  need to upgrade the io.swagger plugin?

No Success ... I have tried 

client.addDefaultHeader("Accept", "application/json");

in 

transitclockTraccarClient/src/main/java/TheTransitClock/transitclockTraccar/GetPositions.java

and it did not  helped.. Traccar seems changes slightly  the API and now i don't know what to do :((((((((

Best Regards

Gevork 

[Gevork Grigorian]

Ok I have found the reason!!!!

Apparently  the problem is in user.getId();

it has  to be removed as when in api call ?id=x is added , the API will return 400error

List<Position> results = api.positionsGet(null, null, null, user.getId());

should be 

List<Position> results = api.positionsGet(null, null, null, null);

i will send a pull request

Is that OK that heading is NAN and speed also NAN?

Ok, sorry, I am slowly getting in. Modified the AVL module of Traccar so that it passes the values.

I wish you nice weekend and Sunday, guys. 

I have passed a long path with Transitclock, and hope you can bear with me  a little bit and I will finalize this project .... 

So 

Now when from traccar I feed right data....  Which you can see down, could you help me to understand better the matching ...?

Now with only the normal  AVL Module of traccar it could match the first bus which started from the first bus , and started to move alongside,  it lost it's route id after second stop (probably because stop was too long?) and when it moved further it did not reassign the route ID to it ....

Could you hint what could be the reason? 

I have tried also to enable Traccar BareFoot AVL  module , but  it seems the format of the data it was sending was not appropriate for BareFoot server , and it was rejecting by saying that "Request" json is missin or something... :(((( 

Could you hint me on the right direction?

Sorry that I am so annoying, but here my settings I come up with reading the code 

transitclock.modules.optionalModulesList=org.transitclock.custom.traccar.TraccarAVLModule

transitclock.autoBlockAssigner.autoAssignerEnabled=true
transitclock.autoBlockAssigner.ignoreAvlAssignments=true
transitclock.autoBlockAssigner.minDistanceFromCurrentReport=1
transitclock.autoBlockAssigner.allowableEarlySeconds=250000
transitclock.autoBlockAssigner.allowableLateSeconds=2500000
transitclock.autoBlockAssigner.minTimeBetweenAutoAssigningSecs=5

What do you think?  Which options else I should consider?

Hi Gevork,

If you look at the log files in the directory that has your core.log file it should give you more information on matching. Also, there is a table in the database called Vehicle Events which will have some useful information.

Cheers,

Sean.

[Gevork Grigorian]

In database I  see there is Vehicle had 3 bad spatial matches in a row and so was made unpredictable. 

Can this be a reason on the former problem? 

How can I  resolve this?

Best Regards

Gevork 

[Óg Crudden]

I suspect your vehicle is too early of too late compared to your schedule. 

Look in coreConfig.log for some of the possible settings and their meaning.

[Gevork Grigorian]

But I have set maxlate and maxearly to a very big number as you see in my former email. Shouldn't it solve the problem?

Best Regards

Gevork 

[Óg Crudden]

You need to look at the config values in coreConfig.log for settings related to auto-assignment.

[Gevork Grigorian]

coreConfig.log  te .java? 

I am still getting very bad predictions :(

Should I try to activate BareFoot ?  It was not working properly , seems the format of request need to be revised.  But maybe the problem  are in the settings...

I wonder is there a setting, which allows to make unpredictible car again predictible automatically after xseconds?

Ok, Barefoot Send from TraccarBarefoot modul was failing, I have modified it to match the newer format that barefoot required which is 

[{pointDataHere}]

it was sent without [] 

https://github.com/TheTransitClock/transitime/pull/157

I have activated both modules but vehicles disappeared 

transitclock.modules.optionalModulesList=org.transitclock.custom.traccar.TraccarBarefootAVLModule;org.transitclock.custom.barefoot.BarefootAVLModule

but cars are not appearing :(
