Criteria for widening of two-lane rural highways

Transport Policy, 2004
Abstract The purpose of this study was to evaluate flow characteristics on two-lane rural highways and to develop criteria for highway widening. The study is conducted on two tracks: theoretical development of delay models and use of a simulation model to estimate the effect of certain parameters on delay and percent-time-spent-following.

Indicators of Performance on Two-Lane Rural Highways

Transportation Research Record: Journal of the Transportation Research Board, 2008
This paper presents an empirical investigation into performance indicators on two-lane rural highways. Field data from four study sites in the state of Montana were used in this investigation. Six performance indicators were investigated: average travel speed, average travel speed of passenger cars, average travel speed as a percent of free-flow speed,

Safety Evaluation Process for Two-Lane Rural Highways [PDF]

, 2007
In the contest of the EU program “ Road Safety in EU: the 1997-2001 program”, the “IASP” project, proposed by the Province of Catania with the scientific support of the Department of Civil and Environmental Engineering of University of Catania, was approved and co-funded by European Commission (DG TREN).

Safety Impact on Accesses in Two-lane Highways

Journal of Highway and Transportation Research and Development (English Edition), 2007
On the basis of substantive investigations and data collection which includes the data of highway alignment, traffic volume, and accidents, the quantitative impact of the accesses on safety performance of 2-lane highways were analyzed. The methodologies such as single- and multi-factors were used.

Evaluation Method of Two-Lane Highway Green Landscape

2010 4th International Conference on Bioinformatics and Biomedical Engineering, 2010
Highway green landscape is an important part of the highway systems. Now freeway and multi-lane highway green landscape have been concerned, but two-lane highway green landscape has not been researched. Through analyzing the function of greening, this paper summarizes a research project that was to develop evaluation models for green landscape ...

Analysis of Two-Lane, Two-Way Highways

2014
The 1950 HCM [1] recognized the critical interaction between directional flows on a two-lane, two-way rural highway. Because of this, in 1950 and 1965, the models for two-lane highways dealt with both directions simultaneously.

Optimal Work Zone Lengths for Two-Lane Highways

Journal of Transportation Engineering, 1999
Highway pavement maintenance is very expensive not only in terms of costs to the responsible agencies, but also in terms of disruptive delays to users. Construction and maintenance activities on two-lane, two-way highways often require the closure of one travel lane.

Highway Alignment Parameters Design and Capacity Analysis on Two-Lane Highway

Applied Mechanics and Materials, 2014
A two-lane highway is an undivided highway with only one lane of traffic in each direction. Two-lane highways are one of the most common roadways at mountainous areas in China. Due to the wider range to choose the horizontal and vertical curves in the design of two-lane highways, the combination of both leads to larger differences on two-lane highway ...

Uncertainty in Operational Analysis of Two-Lane Highways

Transportation Research Record: Journal of the Transportation Research Board, 2002
The Highway Capacity Manual (HCM) 2000 provides methods to estimate performance measures and the level of service for different types of traffic facilities. Because neither the input data nor the model parameters are totally accurate, there is an element of uncertainty in the results.

Operational Performance Assessment for Two-Lane Highway Facilities

Journal of Transportation Engineering, 2009
Transportation professionals have indicated that a facility-based evaluation methodology for two-lane highways would be much more useful and practical to them than just the individual segment and point analysis methodologies. A facility level analysis will allow the various features (e.g., isolated intersections, continuous grades, passing lanes) that ...
