The FSP Loop Data: 09/29/93

Available Detectors:

These are the loop detectors that have recorded data for this day. Whether that data is good or not is a different question.

If a loop detector did not have data for a certain day then the data was generated from the adjacent detectors. A map of the various loop detector locations is available.

Download Data:

You can also download the processed loop data just for this day.

This data has:

The loop data flows.
The loop data speeds.
The loop data occupancies.
The loop data delays.
gnuplot control files to generate the contour plots.

Warning: This file is a tar'ed and compressed file that is approximately 1.5 Mbytes. To understand the file format you'll need to download the fsp manual.

Density Contours:

These are the density contours for this day for each direction and shift. Some things to note about these plots:

Upsteam is always at the bottom of the plot, so traffic flows up.
They were generated with gnuplot and converted to gif files via the PPM tools.
The red boxes with numbers next to them are the incidents that occurred that day. The key to the incidents on the contour plots is available.
Unfortunately, for some irritating reason, gnuplot didn't see fit to put the values of the contours on the plots.

Loop Data Holes:

This is a list of the holes that occurred in the loop data on this day. There is a record below for each loop detector that has a file for this day. The top of the record says something like "Examining file:" and the bottom of the record say "ENDED OK". Everything inbetween is a hole.

WARNING: Holes of with a length of 1 second have been omitted.
