MOTION NO. 2

MOTION: Councillor M. Johansson

That the Chief Executive increase the time for the green/orange light for pedestrians at the Fonthill Rd/Castle Rd junction.

REPORT:

The green and amber man timing at this junction are normally set in accordance with best practice and the requirements of the Traffic Signs Manual.

The pedestrian Phase is calculated like this:

Green time 7 seconds + Intergreen (Amber man) based on walking pace of 1.2 m per second.  Measuring the carriageway to cross.  Example  say 7m cariageway.  7m/1.2 = 5.8 seconds or 6 seconds rounded up.

Therefore the time to cross for a 7m carriageway would be 7 seconds Green man + 6 seconds of Amber man.  Total time to cross = 13 seconds.

An engineer was requested to attend site to determine if any problems exists.

A problem has been identified with the Timings and these have been adjusted. Further improvement work has been identified and these works shall be carried out as soon a practicable.

These items include: Pedestrian detection loops and in one arm of the junction an additional call button on the island.
