Data Sources -- York (Lendal Bridge) Data

This data is from the study of the closure of Lendal Bridge. The map below shows the study area and flows recorded (with direction).

Map of York
Note that locations K,L and M are off the scale of the main map and that locations E and M are split into two files (two lanes of traffic).

The following data from the Lendal Bridge survey is available as zipped text files:

Before studies

27th June
28th June
6th Sept
7th Sept
8th Sept

During closure study

11th Sept Note that 11/9/00 was the first day of the UK fuel crisis and flows will be unusually low.
13th Sept
Note that 13/9/00 was the third day of the UK fuel crisis and again flows will be unusually low.
27th Sept
18th October

After closure study

The after study was severely disrupted by flooding and therefore no data is available.

Additional data

Lendal bridge/fuel crisis flows (excel file showing flows on in the area before and during closure)
Flow location information (excel file showing locations of counters in SATURN and with road names)

All Lendal data chopped so survey starts at 8:00am and ends at 9:00am (note that on rare days the survey starts later or ends earlier due to technical problems - this will be obvious from the file)

Matching software c source code (tar'd and gzip'd) for programs to match plates between sites in various ways is included. It was written for unix but should work on any platform with a good C compiler. The "matchlots" program can be used to produce a matrix of matches between sites. The "convplate" program was used to check the original data for times and to interpolate 1 minute timings from the original 5 minute timings. The "matchplate" program does a simple match for two sites. Note that the numbers on these plates have been scrambled to preserve the privacy of York citizens.
