Roadworks (work zones) are a common feature of our urban environment. They have a considerableimpact on reducing roadway capacity, causing interruptions and imposing substantial delays to roadusers, which in turn adds to the cost to society and adverse impact on road safety. Shuttle-lane (alter-nate one-way working) is one of the most commonly used traffic management arrangements at urbanroadworks as most of the urban road network is built up from single carriageway.Despite the importance of this topic, little attention has been paid to studying drivers’ behaviour interms of close following (tailgating) and amber crossing/red light violations at temporary traffic signals.This paper reports on factors affecting aggressive drivers’ behaviour using observations from six siteswithin Greater Manchester, United Kingdom with over 25 h of video recordings of traffic data from around1500 signal cycles.The findings show that 24% of drivers violate the "two-second rule" of safe following, as recommendedin the Highway Code, before approaching the roadworks site compared to 38% violations after crossing theroadworks site. These results of increased tailgating behaviour are consistent across all sites and for bothtraffic streams and have a direct effect on rear-end collisions or near accidents. Also, the percentages ofdrivers’ non-compliance with temporary traffic signals are higher compared to those for normal signalisedjunctions. The results show that around 30% of cycles were violated where drivers cross the stop line onthe onset of amber and red (18.9% pass through amber and 11.3% run through red lights). Red lightviolations were categorised under four categories as observed on site (dilemma zone, dilemma zonefollower, single violation and group violations). Factors such as site visibility, traffic signals operation (i.e.fixed time or VA) were also reported.
