Traffic and Highway Engineering- Module 2 Concepts
Questions With Complete Solutions
3 types of traffic circles Correct Answers rotaries,
roundabouts, , neighborhood traffic circles
a channelized T intersection in which the two lane through road
has been converted into a divided highway through the
intersection. Correct Answers T intersection with divisional
island and turning roadways
a selected speed to determine the various geometric features of
the roadway Correct Answers design speed
are placed on sealed shoulders or other sealed portion of the
road where traffic is not desired. Correct Answers diagonal
markings
are provided on embankments and fills to provide stability for
earthworks. they also serve as safety feature by providing a
recovery area for out of control vehicles Correct Answers side
slopes.
are raised structures made of either portland cement concrete or
bituminous concrete that are used mainly on urban highways to
delineate pavement edges and pedestrian walkways. Correct
Answers curbs
are usually provided on roads in urban areas, but are uncommon
in rural areas. this should also be evaluated during the planning
, process to determine sections of the road where they are
required. Correct Answers sidewalks
at locations with higher speeds and turning volumes, which
increase the potential or rear end collisions between through
vehicles and turning vehicles, usually an additional area of
surfacing or flaring is provided Correct Answers "T"
intersection with right turn lane
consists of straight sections known as grades (or tangents)
connected by vertical curves Correct Answers vertical
alignment
consists of straight sections of the road connected by curves
Correct Answers horizontal alignment
divided arterial highway for through traffic with full or partial
control of access and generally with grade separations at major
intersections Correct Answers expressway (exp)
for highway design, topography is generally classified into what
three groups? Correct Answers level, rolling, and mountainous
terrain
have diameters that are much smaller than rotaries and therefore
allow much lower speeds. they are used mainly at the
intersections of local streets as a means of traffic calming and/or
as an aesthetic device Correct Answers neighborhood traffic
circles
