Measures of Functional Reliability of Two-Lane Highways [PDF]

open access: yesEnergies, 2021
Rural two-lane highways are the most common road type both in Poland and globally. In terms of kilometres, their length is by far greater than that of motorways and expressways.

Two-Lane Highways: Indispensable Rural Mobility

open access: yesEncyclopedia, 2022
Two-lane highways refer to roadways consisting of two lanes in the cross section, one for each direction of travel. Occasionally, passing lanes may be added to one or two sides of the roadway extending the cross section to three or four lanes at those ...

Performance measures on two-lane highways: Survey of practice [PDF]

open access: yesResearch in Transportation Economics, 2018
Abstract Two-lane highways constitute a significant component of the highway system and serve an essential function for the movement of people and goods. The Highway Capacity Manual is primarily used for operational analysis on two lane highways in the U.S. and Canada.

Development of Direct Models for Percent Time-Spent Following on Two-Lane Highways

open access: yesFrontiers in Built Environment, 2020
The percent time-spent following (PTSF) is a key measure for estimating the level-of-service for two-lane highways. However, PTSF is currently estimated indirectly using various measured field data.

Optimizing speed change lane lengths for two-way ten-lane expressways: a VISSIM and SSAM simulation-based approach [PDF]

open access: yesScientific Reports
With rapid economic development, expressway traffic volumes have surged, resulting in severe congestion. To address this, expanding expressways to two-way ten-lane configurations has become a primary strategy for alleviating traffic pressure.

Optimal Speed Plan for the Overtaking of Autonomous Vehicles on Two-Lane Highways

open access: yesInfrastructures, 2020
In passing maneuvers on two-lane highways, assessing the needed distance and the potential power reserve to ensure the required speed mode of the passing vehicle is a critical task of speed planning.

The “green wave” mode production on the two-lane highways during the construction works time period [PDF]

open access: yesTransport, 2007
In the paper, the problem of a bi-directional “green wave” mode production is considered for the vehicle flows motion on two-lane highways during the conducting of construction works.

Free-Gap Evaluation for Two-Lane Rural Highways [PDF]

open access: yesTransportation Research Record: Journal of the Transportation Research Board, 2011
Studies related to operating speed predicting models' development require vehicles' speed under free-flow conditions to be collected at different sites. Thus, a critical issue is the definition of the gap (or headway) from which the speed of one vehicle is not affected by the speed of the vehicle ahead. In many studies, a 5-s headway was adopted as the

Operating speed prediction model as a tool for consistency based geometric design of four-lane divided highways

open access: yesTransport, 2019
Researchers have studied two-lane rural highways to predict the operating speed on horizontal curves and correlated it with safety. However, the driving characteristics of four-lane-divided highways are different.
