Operating speed models for two-lane rural highways

Proceedings of the Institution of Civil Engineers - Transport, 2012
Drivers adapt their driving to the conditions that they find. When the design corresponds to what a driver hopes to find, the route is consistent. This diminishes the likelihood of drivers making errors and carrying out uncertain manoeuvres. Most evaluations of highway geometric design consistency are based on the analysis of vehicles' speeds.

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. The average daily traffic and

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.

Study of Long Combination Vehicles on Two-Lane Highways

Transportation Research Record: Journal of the Transportation Research Board, 1998
In 1988, the Council of Ministers of Transportation and Highway Safety in Canada endorsed a memorandum of understanding designed to improve uniformity between provinces and territories. The regulations covering weights and dimensions for tractor-semitrailers and double combination trucks specified a maximum length of 23 m.

Cost of Driving Comfort and Convenience for Two‐Lane Highways

Journal of Transportation Engineering, 1989
Described in this paper is the development and calibration of a proposed model for estimating the cost of comfort and convenience related to driving on two‐lane highways. The starting point for the model presented here was an earlier study which showed that the traditional cost factors and variables, when employed with the 1985 Highway Capacity Manual ...

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 ...

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 ...

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.

Probability of Landslide Impact on Vehicles on Two-Lane Highways

2015
The vulnerability displayed by lineal infrastructures, such as highways, is of special concern inside the existing landslide risk assessment methodologies. Their construction often implies the creation of cut slopes with a steeper angle than that displayed by the same material on natural slopes.
