Question 1 The Design of a new freeway with 4 lanes is due to start in August this year. The road will open in 4 years. It is estimated that the present average daily traffic (ADT), in both directions is 10 000 vehicles per day (vpd) with 22% heavy vehicles. Assume the following: ● heavy vehicles averaging 1.6 E80s each • Traffic growth rate 2% per annum during the design and construction period; • Traffic growth rate 4% per annum after opening the road to traffic and • Both the design and analysis period are 25 years. • Lane distribution factor of 0.95 Calculate the cumulative equivalent traffic for the design period and state the traffic class. Cleary show all your calculation steps. REFER TO ANNEXURE X for the required information. [20 MARKS]
