Analysis and Modelling of Passing Sight Distance Using Vehicle Dynamic Response

open access: yesIEEE Access, 2023
Passing Sight Distance (PSD) is pivotal for two-lane undivided highways, impacting their safety and operational performance. However, current PSD standards and models are based on simplistic assumptions and do not consider road characteristics and ...

Estimating passing sight distances for overtaking truck platoons – Calibration and validation using VISSIM

open access: yesInternational Journal of Transportation Science and Technology, 2022
Two-lane highways comprise a substantial proportion of the nation’s highways. One of their critical aspects is the passing sight distance (PSD), which is the minimum distance required for executing a safe passing maneuver using the opposing travel lane ...

Rural Roads’ Passing Sight Distance Control Along Crest Vertical Curves

open access: yesInfrastructures
Passing sight distance (PSD) is a vital design element that directly imposes economic, as well as safety and operational, considerations. The provision of PSD is highly prioritized, at least for rural road sections without additional passing lanes.

Estimation of passing sight distance required for operation of truck platooning on two-lane highways in North America

open access: yesIATSS Research
The most well-known benefits of heavy commercial vehicle (HCV) platooning include fuel savings and emission reductions. In addition, HCV platooning under SAE automation level 4 or 5 can mitigate the truck driver shortage in North America by eliminating ...

Determining Passing Sight Distance on Upgraded Road Sections over Single and Platooned Heavy Military Vehicles

open access: yesInfrastructures
Although truck platooning enhances transportation efficiency, reduces fuel consumption, and lowers freight transport costs, it can also create limited overtaking opportunities, potentially leading to risky overtaking maneuvers. The present study examines

Analytical Model for Passing Sight Distance Design Criteria of Two-Lane Roads in Sri Lanka [PDF]

open access: yesTransport and Telecommunication, 2018
For a safe overtaking manoeuvre on two-lane highways, drivers need a sufficient sight distance along the roadway, but it depends on the traffic environment.

Sight Distance Standards Based on Observational Data Risk Evaluation of Passing [PDF]

open access: yesTransportation Research Record, 2014
The paper presents an application of a reliability analysis for evaluating the risk associated with passing sight distance (PSD) standards in terms of the expected probability of noncompliance. Calculation of PSD is required to determine where drivers can safely execute passing maneuvers.

Incorporating Uncertainty into the Estimation of the Passing Sight Distance Requirements

open access: yesComputer-Aided Civil and Infrastructure Engineering, 2007
Passing sight distance (PSD) is provided to ensure the safety of passing maneuvers on 2-lane, 2-way roads. Many random variables determine the minimum length required for a safe passing maneuver. Current PSD design practices replace these random variables by single-value means in the calculation process, disregarding their inherent variations, which ...

Drivers passing cyclists: How does sight distance affect safety? Results from a naturalistic study

open access: yesJournal of Safety Research, 2023
Cycling is popular for its ecological, economic, and health benefits. However, especially in rural areas, cyclists may need to share the road with motorized traffic, which is often perceived as a threat. Overtaking a cyclist is a particularly critical maneuver for drivers as they need to control their lateral clearance and speed when passing the ...

Highway Stopping Sight Distance, Decision Sight Distance, and Passing Sight Distance Based on AASHTO Models

open access: yesOpen Access Library Journal (oalib), 2020
Highway sight distance is a measure of roadway visibility, which is an important factor in the assessment of road safety. Greater visibility can provide motorists more time to avoid crashes and conflicts, facilitating safe and efficient operation.
