| “The Red shows fine and all that is needed to stop drivers out of either junction. If the green is fully shielded from the CHR junction then the possibility of jumping the lights in error is completely removed. “ Yes but (no but)… If they are too low then drivers coming through both junctions at a reasonable speed can’t see whether or not there is a green signal or a blank signal in adequate time to react accordingly. If you can’t see a green signal at say 25mph you should be braking to ensure the signals are not out of action, in case a pedestrian is about to cross. This uncertainty happens at several junctions I could name where the louvres are set too low, eg upon leaving the Chiswick Roundabout to go onto the A4 westbound, where drivers sometimes come to a sudden and unnecessary halt because they see the sun reflecting off the red signal and they cannot see the green behind the louvre. PS: was the Louvre in Paris at the right angle? :-) |
