Speed-flow data from California.
Description
A ‘fundamental diagram’ with observations of speed and flow recorded from 9th of July 2007, 9am, to 10th of July 2007, 10pm, on Line 5 of the Californian Freeway SR57-N, VDS number 1202263. The data were originally measured in intervals of thirty seconds, and then aggregated over intervals of 5 minutes length.
Usage
data(calspeedflow)
Format
A data frame with 444 observations on the following 4 variables.
Datea factor with levels 07/09/2007... 07/10/2007.
Timestampa factor with a timestamps in intervals of five minutes.
Lane5Flowa numeric vector of vehicle flow in vehicles per 5 minutes.
Lane5Speeda numeric vector of vehicle speed in miles per hour.
