Turn-location parameters for a continuous landing model. I. Road tangents

Canadian Journal of Forest Research, 1994
Timber harvesting operations often employ continuous landings on or along truck road right-of-ways. During the harvest-unit design process forest engineers describe the spatial distribution of turns with respect to a proposed landing by distribution parameters such as average yarding distance and average yarding slope.

Effect of geometric road characteristics on deceleration rate in transition from tangent to horizontal curve for two-lane rural roads

International Conference on Road and Rail Infrastructure, 2022
Evaluation of geometric design consistency presents an important safety aspect in road design. The most commonly used consistency criteria are based on defining operating speed variations along the road segment, usually by depicting operating speed profiles.

PREDICTION OF THE MAXIMUM LEVEL OF TANGENT STRESSES IN THE ASPHALT CONCRETE SURFACE LAYING ON THE CONCRETE BASE OF A MOTOR ROAD

Automobile Roads and Road Construction, 2023
In this paper, in order to evaluate the tangential stress levels in the asphalt concrete coating arranged on concrete foundation, finite element modeling of various constructions of road clothing with different values of the thickness of the asphalt layer and its modulus of elasticity, was carried out.

Tangent-to-Curve Transition on Two-Lane Rural Roads Based on Continuous Speed Profiles

Journal of Transportation Engineering, 2013
[EN] In the road geometric design process, speed variation along the road segment is one of the most popular criteria to evaluate road consistency, hence the importance of estimating operating speed and its variations. Most of the estimation models are based on speed spot data collection, usually assuming some hypotheses like operating speed remains ...

Stop-Controlled Intersection Sight Distance: Minor Road on Tangent of Horizontal Curve

Journal of Transportation Engineering, 2009
Sight distance at the intersection of a minor road (controlled by a stop sign) and a major road is an important element of road safety. Several models have been recently developed for the analysis of sight distance at intersections involving horizontal curves on the major road.

Safety performance functions for horizontal curves and tangents on two lane, two way rural roads

Accident Analysis & Prevention, 2018
Horizontal curves on two-way, two-lane rural roads pose critical safety concerns. Accurate prediction of safety performance at these locations is vital to properly allocate resources as a part of any safety management process. The current method of predicting safety performance on horizontal curves relies on the application of a safety performance ...
