Other/Glossary

A#

  • application

    An application is a computer program, herein, an "application" mostly means one of the main, compiled programs that are included in the SUMO package.

  • additional-file

    A file that can be included in a sumo configuration. This is needed to load pois, shapes, bus stops and variable speed signs. Refer to the format description for details.

C#

D#

  • DELPHI

    Deutschlandweite Echtzeit Verkehrs-Lage und Prognose im Ereignisfall

  • destination

    The position of the end of a vehicle journey. Mostly a TAZ processed by OD2TRIPs within which a "sink" edge lies

  • detector

    An artificial device for object (mainly vehicle) states recognition and/or logging

  • DFD

    Deutsches Fernerkundungsdatenzentrum des DLR

  • district

    see TAZ

  • DLR

    Deutsches Zentrum für Luft- und Raumfahrt

  • DUA

    Dynamic User Assignment

  • DUE

    Dynamic User Equilibrium

E#

  • edge

    A single-directed street connection between two points (junctions/nodes). An edge contains at least one lane

F#

  • FCD

    Floating Car Data

I#

  • induction loop

    A detector placed on a certain position on a lane which recognizes vehicles passing it and logs their attributes (speed, size, etc.)

J#

  • junction

    The place an edge begins or ends at (same as node)

  • junction logic

    The part of a junction which determines the vehicle behaviour at the according junction by using certain right-of-way - rules

L#

  • link

    A connection between two lanes within a junction. Within microsim, each lane has links (connections) to the following lanes. A link contains the information whether the vehicle has to decelerate in front of the junction.

M#

  • macroscopic

    In a macroscopic traffic (flow) simulation, the atomic instances are roads; the flow is simulated directly (see microscopic)

  • mesoscopic

    In a mesoscopic traffic (flow) simulation, the streets are partitioned into sections which multiple vehicles may enter and leave at each simulation step

  • microscopic

    In a microscopic traffic (flow) simulation, the atomic instances are vehicles; the flow is simulated by simulating the vehicles (see macroscopic)

  • multimodal

    A multimodal traffic simulation is capable of processing different types of traffic (busses, trains, vehicles etc.)

N#

  • (street) network

    In our terms, a network is the combination of junctions (nodes) and edges (streets)

  • node

    A node (junction) is a single point were at least one edge (road) starts or ends

O#

  • O/D-matrix (od-matrix)

    Origin/Destination-matrix; describes how many vehicles are moving from each origin to each destination within a certain time period

  • option

    A parameter for the application which determines what or how an application shall do

  • origin

    The position of the begin of a vehicle journey. Mostly a TAZ processed by OD2TRIPs within which a "source" edge lies

P#

  • poi

    short for "point of interest"; A position of an object that may be interesting

R#

  • route

    A route is a complete description of a vehicle's path over the network; it contains the information when the vehicle departs (the route starts) and over which edges the vehicle shall drive

S#

  • script

    A small computer program which normally doees not have to be compiled. The SUMO package includes several scripts, most written in Python

  • source

    A source means a place at which vehicles are inserted into the street network

  • source-tar-ball

    A file containing the sources (program code) for a project. The source code must be compiled in order to get the runnable application. It is called "tar-ball" because of using the application "tar" to join all the source files into a single file.

  • submicroscopic

    In a submicroscopic traffic (flow) simulation, the atomic instances are parts of the vehicle or the driver (gearing or behavior is modelled)

T#

  • TLS

    traffic lights system

  • trip

    A reduced information about a vehicle's movement; contains only the departure time, the begin, and the end edge. Must be transformed into a route using a router for being used within the simulation

  • trip-table (trip list)

    A file containing several trips

  • TS

    Institute of Transportation Systems at the German Aerospace Center (DLR)

  • TS-BS

    TS Standort Braunschweig

  • TS-BA

    TS Standort Berlin-Adlershof
