“…In preparation for the era of CAVs, highway infrastructure requires upgrades to facilitate CAV operation to minimize the possibility of disengagements. In the interim period, numerous roadworks are taking place in preparation for CAVs and intelligent mobility [10]. Currently, the impacts of roadworks with mixed traffic (i.e.…”

“…Therefore, there is a need for developing dynamic frameworks to understand CAV navigation within roadworks. In particular, more research has to be dedicated to understanding the interaction between CAVs, their systems, and conventional vehicles at roadworks [10]. As a result, in this study, a microsimulation model was developed to examine the impact of traffic performance and safety in two TTM schemes for roadworks (NLs and LC) with different MPR of CAVs.…”

“…This is crucial at congested roadworks zones as it allows higher capacity on the road network and quicker queue dissipation. Rerouting also reduces the traffic demand at roadworks zone because it allows drivers to make timely decisions to change to multiple rerouting options and do not have to wait to detect a warning of roadworks zone upstream [10]. Moreover, due to the dynamic changes happening in roadworks zones, all vehicles frequently change their speed resulting in speed oscillations.…”

“…Roadwork zones tend to increase travel time, queue, accidents and dissatisfaction amongst road users [6,10]. Utilizing the advanced vehicular communication technology, CAVs have the potential to improve traffic performance at roadworks by exchanging information of the traffic conditions ahead as well as recommending a driving speed in a timely manner to smoothen the traffic flow [10,12].…”

Connected and automated vehicles (CAVs) are being developed and designed to operate on existing roads. Their safe and efficient operation during roadworks, where traffic management measures are often introduced, is crucial. Two alternative measures are commonly applied during roadworks on motorways: (i) closing one or multiple lanes (ii) narrowing one or all lanes. The former can cause delays and increased emissions, while the latter can pose safety risks. This study uses a VISSIM‐based traffic microsimulation to compare the effectiveness of these two strategies on traffic efficiency and safety, considering various market penetration rates (MPR) of CAVs. The model was calibrated and validated with the data collected from M1 motorway in the United Kingdom. Results show that average delays per vehicle‐kilometre‐travelled decreased from 102.7 to 2.5 s (with lane closure) and 23.6 to 0.6 s (with narrow lanes) with 0% and 100% CAV MPR, respectively. Moreover, safety in narrow lanes improved by 4.8 times compared to 1.5 times improvement in lane closure with a 100% CAV MPR; indicating that narrow lanes would result in better safety performance. These findings could assist transport authorities in designing temporary traffic management measure that results in better CAV performance when navigating through roadworks.

“…Given that the majority of work zone-related events can be avoided with early alerts to vehicles, safety research relating to work zones in a CV environment is an emerging area of research ( 9 ). Vehicle-to-infrastructure (V2I) communication, enabling a low latency communication channel, such as dedicated short-range communication (DSRC) ( 10 ) and upcoming 5G technology, may dramatically improve work zone safety.…”

Work zones, being a critical component of roadway transportation systems, can benefit greatly from computer vision-enabled roadway infrastructures, specifically in connected vehicle (CV) environments. Connected infrastructures, such as roadside units (RSU) and on-board units (OBU), can greatly improve the environmental awareness and safety of CVs driving through a work zone. The contribution of this paper lies in developing a vision-based approach to generate work zone safety messages in real time, utilizing video streams from roadside monocular traffic cameras that can be used by CV work zone safety apps on mobile devices to reliably navigate through a work zone. A monocular traffic camera calibration method is proposed to establish the accurate mapping between the image plane and Global Position System (GPS) space. Real test scenarios show that our algorithm can precisely and effectively locate work zone boundaries from a monocular traffic camera in real time. We demonstrate the capabilities and features of our system through real-world experiments where the driver cannot see the work zone. End-to-end latency analysis reveals that the vision-based work zone safety warning system satisfies the active safety latency requirements. This vision-based work zone safety alert system ensures the safety of both the worker and the driver in a CV environment.
