Speed Variability on Rural Two-Lane Highways
Transportation Research Record: Journal of the Transportation Research Board, 1999A better understanding of speed variance on rural two-lane highways may assist in addressing driver error associated with highway geometric elements. Previous research has identified a direct relationship between speed variance and accident potential. Speed variance increases are associated with an increase in accidents.

Analysing the effect of foggy weather on drivers’ speed choice in two-lane highways
Proceedings of the Institution of Civil Engineers - Transport, 2020Foggy weather can reduce visibility for drivers and one of the main consequences of this condition can be the change in behaviour regarding choice of speed, which will vary from driver to driver ow...

Traffic characteristics on two-lane highway downgrades
Transportation Research Part A: Policy and Practice, 1996Downgrade operations are not specifically addressed in the 1985 Highway Capacity Manual procedures for two-lane highways. However, traffic operations on long steep downgrades on two-lane highways are becoming increasingly important due to increasing volumes and the higher percent of slow moving vehicles such as recreational vehicles and heavy trucks in

Level of Safety on Two-Lane Undivided Rural Highways
Applied Mechanics and Materials, 2012Due to the great increase of congestion levels on transportation infrastructures researchers and practitioners have focused on the study of safety performance on road network to identify unsafe locations and assess the effectiveness of different countermeasures introduced at a given site to reduce unacceptable accident risk. Safety performance measures

Horizontal curves are associated with a disproportionate number of severe crashes, particularly on two-lane rural highways. Many efforts have been placed to improve curve safety and efficiency; however, in many previous studies the curve safety and ...

Speed-Profile Model for Two-Lane Rural Highways
Transportation Research Record: Journal of the Transportation Research Board, 2000Design consistency refers to highway geometry’s conformance with driver expectancy. Generally, drivers make fewer errors at geometric features that conform with their expectations. A proposed method for evaluating design consistency is to predict the speed along an alignment by using a speed-profile model.

Two-lane highways, which have one lane per direction, are unique operationally, since they may allow passing through the use of the opposing traffic stream. According to the US Federal Highway Administration [1], two-lane highway facilities represent about 97 % of the total highway system and for more than 65 % of the total nonurban vehicular travel in

Operating speed models for two-lane rural highways
Proceedings of the Institution of Civil Engineers - Transport, 2012Drivers 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.
