Assignment 3 : Horizontal Curve Design
Question 1
A transition curve is required to connect two intersecting straights whose
deflection angle (0) is DD° dd’ dd" by a circular curve of radius XXX metre. The
though chainage of the intersection point (IP) is YYYY metre and pegs required
on the centre line of the road curve at exact 20 metre multiples of through
chainage. Bearing from T, to IP and coordinates at IP given as BB° bb’ bb"
and (Northing, Easting), respectively. While proposed design speed and
acceleration rate (a) are (SS)km/h and (AA) ms³, respectively. As a site
engineer you are required to prepare and verify the setting out data for the
proposed transition road curve design using tangential and chord distance
based on proposed design parameters given by project consultant.
