Topic 2-
Stopping sight distance (SSD) is the sight distance required by a driver to see a hazard in the road ahead, react, and then stop in time before impacting the hazard. It is determined by the following formula:
SSD = (RTV/3.6) + (V2/254(d+0.01a))
RT = reaction time (sec)
V = operating speed (km/h)
d = coefficient of deceleration (longitudinal friction factor)
a = longitudinal grade (%, + for upgrades and - for downgrades).
A road authority has been using a driver reaction time of 1.5 seconds, and a coefficient of deceleration of 0.46 in its road designs. They have been asked to increase the driver reaction to 2 seconds and reduce the coefficient of deceleration to 0.36, to be consistent with the rest of the country. You are required to write a technical note of 800 words or less to qualitatively explain the cost/ financial implications that this will have on modifying existing road network. In your response, you have been specifically requested to discuss the impact of the new SSD requirements on curved road sections.
