Simulation window, Insert type

At the beginning of the track you can select the insert type for the vehicle.

• normal: When a vehicle reaches the end of the track it will be inserted at the beginning of the track again. The insert speed and the insert lane of the vehicle accord with the speed and lane, the vehicle left the track with. The desired headway range of the corresponding driver is determines the insert time .

• microscopic: The vehicles are inserted according to the file mikein.data. The speed can be set as positive or negative values. Positive speed means that the vehicles are inserted at the specified speed irrespective of the traffic situation. Neagtive speed means that the vehicles are only inserted at the specified speed if the traffic situation tolerates it. Otherwise the insert speed will be adjusted or the vehicle will be not inserted as the worst case (congestion with stagnation at the end of the simulation window).

• macroscopic: The file makein.data contains macroscopic minute values for the insert type of the vehicles, such as would be provided by a measuring loop. Individual vehicle data is calculated from these macroscopic minute values and the vehicles are inserted at the beginning of the track accordingly. The individual vehicle data then would result the mean macroscopic data again. Here the mean speed can be defined as a positive or negative value, too. In case of a negative value an adjustment of speed with respect to the traffic situation is done automatically. An example for a macroscopic insert file is shown here:

• endless loop: The vehicles, which leave the track, respond to vehicles, which are re-inserted at the beginning of the track. This simulates a circular world since the end of the track apparently disembogues to its beginning. This insert type in general is just utilized to imitate a single point of the fundamental diagram.

• intermediate memory
• simulation window length

• simulation window type: You can differentiate between a fixed and a moving window. The fixed window remains stationary; the moving window is a window of constant size around a reference vehicle. When selecting a moving window you must enter the number of the reference vehicle and its distance to the start of the window in the opened field. You can also determine a random number of measuring loops via their position within the simulation window. This is sensible only for fixed simulation windows. The virtual measuring loops write the data of the vehicle, which has just passed them, in a result file and thus enable a comparison of the simulation results with real loop data.
