Transit vehicle is not yet at last stop!

Hi, friends!

I have created my toy multimodal transportation scenario (network,plans, transit schedule and vehicles xml files). Initial plans have only car legs. When I try to run my scenario I get the next error:

ERROR AbstractTransitDriverAgent:296 java.lang.RuntimeException: Transit
  vehicle is not yet at last stop! vehicle-id = tr_1; next-stop = 11

The transit schedule has only one pt line with the next configuration:

<transitStops>
     <stopFacility id="11" x="5.3" y="12.4" linkRefId="1211" name="Main" isBlocking="true"/>
     <stopFacility id="21" x="9.6" y="17.6" linkRefId="1121" name="First" isBlocking="true"/>
     <stopFacility id="31" x="14.8" y="12.2" linkRefId="2131" name="Second" isBlocking="true"/>
     <stopFacility id="41" x="19.8" y="17.6" linkRefId="3141" name="Third" isBlocking="true"/>
 </transitStops>
 <transitLine id="Line1">
 <transitRoute id="11to41">
     <transportMode>pt</transportMode>
 <routeProfile>
     <stop refId="11" departureOffset="00:00:00"/>
     <stop refId="21" departureOffset="00:04:20"/> 
     <stop refId="31" departureOffset="00:08:00"/>
     <stop refId="41" arrivalOffset="00:10:00" />
 </routeProfile>
 <route>
     <link refId="1121"/>     
     <link refId="2131"/>
     <link refId="3141"/>    
 </route>
 <departures>
     <departure id="1" departureTime="06:00:00" vehicleRefId="tr_1" />
     <departure id="2" departureTime="06:15:00" vehicleRefId="tr_2" />    
     <departure id="3" departureTime="06:30:00" vehicleRefId="tr_1" />
     ...
 </departures>
 </transitRoute>

The network has the "car,bus" links to guaranteed the bus route. However, I do not understand what is wrong.

I have attached the log and scenario files.

Any suggestion?

Thanks!

Hi Rolando,

the route of your transit line must contain all links of the network route including those with stops.

In Your case link 1211 is not part of the route, but stop 11 is.

Adding

<route>
     <link refId="1211"/>     
     <link refId="1121"/>     
     <link refId="2131"/>
     <link refId="3141"/>    
 </route>

should do the trick.

Explanation: The route (the actual link-sequence the vehicle has to drive) you provided does not contain the link of the first stop (link 1211). So the vehicle drives the full route but never reaches the first stop (you see in the error message that vehicle tr_1 is still looking for stop 11), and it is ergo never even looking for the other stops. At the end of the route it realizes that it "is not yet at the last stop", which results in the error message.

Bugfix: Add

<link refId="1211"/>

as the first entry of the route (assuming that link 1121 can be reached from link 1211).

There is also a validator to check this:

 Schedule is NOT valid!

 Validation errors:

 Transit line Chaguarkingo, route 11to41: Stop 11 cannot be reached along network route.
