Two-Lane Highways: Indispensable Rural Mobility [PDF]
Encyclopedia, 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 ...

2 + 1 Highways: Overview and Future Directions [PDF]
Advances in Civil Engineering, 2018 Most of the rural transportation system is composed of two-lane highways, and many of them serve as the primary means for rural access to urban areas and freeways.

Determining Free-Flow Speed on Different Classes of Rural Two-Lane Highways
Promet (Zagreb), 2023 Current analytical free-flow speed models consider all rural two-lane highways as the same road type despite their different functional significance in the network.

Measures of Functional Reliability of Two-Lane Highways [PDF]
Energies, 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 Crest Curve Design. The Case Study of Italian Guidelines [PDF]
Applied Sciences, 2020 The main purpose of the research is to evaluate the crest vertical curves radii Rv, not considering a conventional value of the opposing vehicle height h2, but the average vehicle heights h2(m) and the value of the 15th percentile of the height ...

Operational Impact of Horizontal and Vertical Alignment of Two-Lane Highways [PDF]
Journal of Advanced Transportation, 2016 SummaryThe US Highway Capacity Manual (HCM) methodology is used in Spain to evaluate traffic operation and quality of service. The effect of passing manoeuvre on two‐lane highway operational performance is considered through adjustment factors to average travel speeds and percent time spent following.

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

A realistic two-lane traffic model for highway traffic [PDF]
Journal of Physics A: Mathematical and General, 2002 A two-lane extension of a recently proposed cellular automaton model for traffic flow is discussed. The analysis focuses on the reproduction of the lane usage inversion and the density dependence of the number of lane changes. It is shown that the single-

Traffic Delays Estimation in Two-lane Highway Reconstruction
Procedia Computer Science, 2014 AbstractAn increasingly important issue, as congestion levels increase more and more, is that freeways become subject to rebuilding and restructuring when traffic cannot be re-routed. It has already been asserted that traffic simulation provides a better approach to the analysis of freeway reconstruction than the traditional Highway Capacity Manual. In

Critical radius prediction for small radius curved section of two-lane secondary highways based on speed characteristics [PDF]
HeliyonSmall radius curved sections of two-lane secondary highways have low technical indicators, complex alignments, and frequent accidents. In order to improve the safety of traffic operation, the article investigates the curved sections of two-lane secondary
