The client is included as part of each SUMO release in Is a client library with almost complete API coverage. Provides a C++ client library for the TraCI API (API completeness is (APIĬoverage is almost complete but this client is no longer updated. Library that is part of the sumo-source tree.

C++: libtraci is a client library that is part of the sumo-source tree.

Is tested daily and supports all TraCI commands). To interact with sumo using Python (This library Resources # Interfaces by Programming Language # Tutorial uses TraCI for building a crossing with a pedestrian Uses TraCI for assigning new routes to vehicles (using Python).

There is a tutorial on using TraCI for adaptive traffic.

C++, Java and Pythonīindings are included when downloading a sumo-build. With a large number of programming languages. Libsumo supports generating client libraries using In the client libraries but avoids the overhead of socket communication. This allows using the same method signatures as Libsumo can be used to embed SUMO as a library Process and one or more TraCI client processes. Normally, TraCI is used to couple multiple processes: A SUMO server It is also possible to reload the simulation with a new list of The simulation will end as soon as all clients have sent the Have left the simulation, one can check whether the command To detect whether all route files have been exhausted and all vehicles Instead the simulation is closed by issuing the close When using TraCI, the -end option of sumo is ignored.

Point-of-interest's state (or add/remove one)Ĭhange a polygon's state (or add/remove one) Retrieve information about the RouteProbe Retrieve information about the simulation visualization Retrieve information about overhead wires Retrieve information about charging stations Retrieve information about points-of-interest Retrieve information about traffic lights Retrieve information about multi-entry/multi-exit detectors Retrieve information about lane area detectors Retrieve information about induction loops Simulation step, close the connection, reload the simulation.įor the following APIs, the ID is equal to the ID defined in Please see the TraCI Protocol Specification The simulation will only start once all clients have connected. Also, the simulationStep command only returns control to the client after the simulation has advanced. This means, the simulation does not advance to the next step until all clients have called the 'simulationStep'' command. The clients are automatically synchronized after every simulation step. The highest value within each simulation step. Scenarios you must explicitly specify the execution order of the clientsĮach client must specify a unique (but otherwise arbitrary) integer valueĪnd the client commands will be handled in the order from the lowest to

Option -num-clients, where 1 is the default. The number of clients which can connect can be given as an additional When using sumo-gui as a server, the simulationīefore TraCI commands will be processed. Runs until the client demands a simulation end. Please note, that the -end option is ignored when Simulation and waits for all external applications to connect and take When started with the -remote-port option, sumo only prepares the Port sumo will listen on for incoming connections. That is started with additional command-line options: -remote-port where is the TraCI uses a TCP based client/server architecture to provide access to Retrieve values of simulated objects and to manipulate their behavior

Giving access to a running road traffic simulation, it allows to TraCI is the short term for " Traffic Control Interface".
