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 ...

Passing lane optimum length on two-lane highways

Canadian Journal of Civil Engineering, 2019
An investigation into the optimum length of passing lanes on rural two-lane highways is presented in this paper. A passing lane is a short length of added lane to improve passing opportunities on two-lane two-way highways. The study utilized field data and traffic simulation in this investigation, with field data primarily used in calibrating and ...

Impact of highway consistency on capacity utilization of two-lane rural highways

Canadian Journal of Civil Engineering, 1999
Consistent highway design is expected to provide safe, economical, and smooth traffic operation. Several studies have been performed to investigate the effect of highway consistency on traffic safety. However, the relationship between design consistency and highway capacity and level of service has not been addressed in current research work and ...

Procedures for Estimating Accident Reductions on Two‐Lane Highways

Journal of Transportation Engineering, 1992
Accident prediction models or the before-and-after study approach is commonly used to estimate the reduction in number of accidents resulting from highway improvements. The highway improvement evaluation results will depend on the approach used, if the two approaches do not yield the same number of accidents reduced.

Passing Activity on Two-Lane Highways in Spain

Transportation Research Record: Journal of the Transportation Research Board, 1999
Presented in this paper are the results of research on passing activity on two-lane highways in Spain. The data were gathered on three highways in the province of Madrid, Spain (M-111, M-600, and M-607). Measurements were carried out in 3-h periods, on plain or slightly sloping ground, and for daily or weekly peak periods.

Queueing delay models for two-lane highway work zones

Transportation Research Part B: Methodological, 1999
The paper describes the adaptation and application of queueing models to estimate average delay at two-lane highways operating with a lane closure. In their original form, the queueing models predicted impacts at highway intersections controlled by vehicle-actuated traffic signals.
