Part Time Through Junction Running (PT TJR) refers to a novel hard shoulder running scheme whereby the hard shoulder through junctions is opened depending on traffic volume. To test participants’ behaviour in response to this scheme in terms of their ability to respond to the new scheme (including signs and road marking) in a safe and appropriate manner, a simulator study was conducted. 72 drivers (Younger: 17-44 years; n=38, Older: 45+ years; n=34) were repeatedly exposed to a junction designed to replicate the key characteristics of junction 5 on the M42 Southbound specifically. The design required each participant to drive two routes in the simulator for a period of around 30 minutes each. The two routes differed in the placement of the full time and part time through junction running sections and in the status of the hard shoulder, or Lane Below Signal 1 (LBS1), through the route. The results of this study were largely positive indicating a good understanding and use of the scheme without compromising road safety. (Author/publisher)
