Speed Survey, Blackhall Rocks

The Traffic Management Officer from Durham Police has sent us the outcome of a speed survey carried out along the A1086 at Blackhall Rocks earlier this year following reports from residents of speeding vehicles on Broad Road. The data is published in full below:

Apologies for the delayed response.

There were two new 7 day 24 hour speed surveys we needed:

1)      Blackhall Rocks (south east of Hart Crescent)

2)      Blackhall Colliery (near Blackhall Primary School)

It appears that speed survey 1) has been done by DCC but speed survey 2) is still awaited.

In relation to 1) Blackhall Rocks I have reviewed the data and compared it with a previous speed survey in the same vicinity and the following results are noted (the shaded area is the percentage of vehicles within Police enforcement threshold)

Date of Survey	Average Daily Traffic Flow	≤30 MPH	31-35 MPH	36-40 MPH	41-45 MPH	≥46 MPH	Mean Speed
02/08 – 09/08/07	10620	26%	48%	20%	4%	2%	32 mph
30/01 – 06/02/20	10123	47%	38%	11%	3%	1%	30 mph

From the data it is evident that the level of offending has significantly reduced with the average mean speed now being around the 30 mph speed limit.

The previous survey (in 2007) showed 26% of vehicles travelled at speeds where Police speed enforcement would be considered and on the latest survey this has reduced to 15% offending.

This has now pleasingly dropped to our borderline figure for Police attention but I’ll put it out to our Roads Policing Unit for attention in the future.
