Traffic Flow


Traffic flow times from a simulation with timed and flexible traffic lights


A data frame with 24 observations on the following 3 variables.

  • Timed Delay time (in minutes) for fixed timed lights

  • Flexible Delay time (in minutes) for flexible communicating lights.

  • Difference Difference (Timed-Flexible) for each simulation


Engineers in Dresden, Germany were looking at ways to improve traffic flow by enabling traffic lights to communicate information about traffic flow with nearby traffic lights. The data in show results of one experiment where they simulated buses moving along a street and recorded the delay time (in seconds) for both a fixed time and a flexible system of lights. The process was repeated under both conditions for a sample of 24 simulated scenarios.
