Abstract:
Roadworks projects, while necessary to upgrade and maintain our transport networks, are loathed for their presumed negative impact on our daily commute. The purpose of this study is to investigate how Floating Car Data (FCD) can be used to assess the influence of a work zone on traffic progression. The effective change in speed and travel time was examined within and around a work zone of the recently completed upgrade of the N1 in Cape Town, particularly during the lane closure of the inbound section of the N1 between Durban Road and Jip de Jager Drive. The use of FCD to assess the impact of work zones provided unprecedented insight into traffic patterns such as the change in position of bottlenecks during roadworks. FCD was shown to improve our understanding of traffic movement within work zones. This can provide input to strategies for safer traffic accommodation during roadworks, going some way to improve the daily commute of road users.
