Travel time

from Wikipedia, the free encyclopedia

The travel time, travel time or travel time is the time that vehicles need to get from point A to point B. This also includes stays in front of traffic lights or in traffic jams .

Meanings

When traveling by car or bicycle, the travel time is often equated with the difference between the time of departure at a certain location and the time of arrival at the destination. It is estimated or determined by means of route planners or with the help of navigation systems . Travel time is an important factor in determining the likelihood of choosing this route . It thus flows into the forecast of traffic flows and the expected traffic density on new or changed traffic routes .

It is relatively easy to determine the travel time for cable cars , ferries and similar line-related means of transport that (usually without stopping) only travel between two points.

The real meaning is the travel time in public transport by bus and train ( train , tram , underground , etc.). Here the travel time forms the basis for drawing up the timetable . A distinction is made between the following designations:

  • pure driving time , that is the necessary driving time between two points without stopping time and without driving time surcharges,
  • Shortest travel time , that is the travel time that can be achieved while observing the maximum permissible speed and utilizing the full drive power of the means of transport
  • Scheduled travel time , which is calculated from the pure travel time plus the travel time supplements for braking and starting , for slow driving and overtaking as well as safety supplements (buffer times) necessary for compliance with the timetable.

If the travel time is added to the time spent at stops and other disability times, the travel time is calculated (sometimes referred to as the transport time).

In city traffic, the random stops at traffic lights are tacitly included in the calculation of the (pure) travel time; in the case of railway systems , these are recorded or calculated separately. In this respect, there is always a difference between the observed (measured, empirically determined) and the driving time calculated using the methods of driving dynamics (driving time determination process).

Use cases in public transport

From the definition of travel time in public transport:

  • the travel time of a means of transport from one station to the next station without intermediate stops a travel time,
  • the travel time of a means of transport from one station to the next station with at least one intermediate stop a travel time, even if it is one and the same line.
  • The travel time from A to B with a change is a "complex travel time" and
  • the term driving t time synonymous with either "travel time" or "travel", depending on the application, occurring as 'travel time' is not an independent concept of Transport Economics.
