Evaluation of speed–flow characteristics on two-lane highways with mixed traffic
Transport, 2017 The HCM (Highway Capacity Manual 2010) classifies two-lane rural highway that passes through developed areas as ‘Class III’ and suggests using Percent Free-Flow Speed (PFFS) as performance measure to define Level Of Service (LOS).

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

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

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

Map Matching-Based Driving Lane Recognition for Low-Cost Precise Vehicle Positioning on Highways
IEEE Access, 2021 This paper proposes a map matching-based driving lane recognition system for low-cost precise vehicle positioning on highways. The proposed method finds the position where the road boundaries detected by a LIDAR sensor are best matched with the road ...

Two-Lane Highways Crest Curve Design. The Case Study of Italian Guidelines
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 ...

Evaluation of risk factors for road accidents under mixed traffic: Case study on Indian highways
IATSS Research, 2022 This paper presents an evaluation of risk factors for highway crashes under mixed traffic conditions. The basis of selecting study sites was abutting land use, roadway, and traffic characteristics. Accordingly, the study selected thirteen segments on the
