Red light running and close following behaviour at urban shuttle-lane roadworks

The findings show that 24% of drivers violate the “two-second rule” of safe following, as recommended in the Highway Code, before approaching the roadworks site compared to 38% violations after crossing the roadworks site. These results of increased tailgating behaviour are consistent across all sites and for both traffic streams and have a direct effect on rear-end collisions or near accidents. Also, the percentages of drivers' non-compliance with temporary traffic signals are higher compared to those for normal signalised junctions. The results show that around 30% of cycles were violated where drivers cross the stop line on the onset of amber and red (18.9% pass through amber and 11.3% run through red lights). Red light violations were categorised under four categories as observed on site (dilemma zone, dilemma zone follower, single violation and group violations). Factors such as site visibility, traffic signals operation (i.e. fixed time or VA) were also reported.
