[sumo-user] Problem with adding new vehicle via TraCI

[Hanyang Z. <hz...@uo...>]

Hi all,



  I'm trying to add new vehicles to a simulation via TraCI. The vehicle types and routes won't load until the first vehicle is generated, which means I cannot add new vehicles in time step 0 - sumo will report the vehicle types and route ids are unknown. This is not a big problem.

  In step 1 or later, when I try to add a vehicle, I receive the following error:



Error: Answered with error to command 116: Wrong position in requestMessage after dispatching command. Expected command length was 76 but 68 Bytes were read.



I'm using command 0x74 and the request message is as follow:



(dec) 0 0 0 68              64                         116                 0 0 0 1  "0" 0 0 0 3   "car" 0 0 0 13 "123456789abcd"  0 0 0 13 "123456789abcd"

        [Message Length] [Command Length] [Command ID] [Vehicle Id] [Vehicle Type] [Route                         Id] [Lane                           Id]

Can someone tell me what I am missing? Thanks.



Kind regards,
