Highway alignment designcubic parabolavertical curveminimum lengthExisting highway vertical curves may be grouped into two categories: symmetrical vertical curves and unsymmetrical vertical curves, hi the past vertical curves design, parabolic arc was used as the vertical curve. This paper presents the ...
aALIGNMENT WITH STRATEGY 对准线以战略 [translate] a与传统教学方式比较,多媒体教学在大学英语教学中的优势不言而喻,然而,目前仍存在不少弊端。 Compares with the traditional teaching way, the multimedia teaching are self-evident in the university English teaching superiority, however, still had many ...
When designed, horizontal and vertical highway alignment components are parametrically-describedgeometric objects (e.g., smooth curves and straight lines). On the other hand, surface models resultingfrom design, and for automated machine guidance (AMG) during construction, are not geometricallysmooth. ...
Minimum radius requirements for reverse horizontal curves are currently based on the design of each arc as a separate simple horizontal curve on flat terrain, with the effects of reverse horizontal curvature and vertical alignment being ignored. This paper establishes minimum radius requirements for truc...
These use cases are based on the urban highway project in Marseille, France, the L2 project (Fig. 4). It is a 10 km connection between two other highways inside the city. At present, this project is the most important infrastructure construction site in France. Registration of the project...

On April 27 and 28, 1993, the National Highway Traffic Safety Administration (NHTSA), U.S. Department of Transportation, assembled a panel of 11 national and international experts in traffic safety at the Belmont Conference Center, Elkridge, Maryland. The group was convened to identify research...
