Problem 1:Level of Service(15points)State Highway 73 is a major east-west South Island state highway in New Zealand connecting Christchurch on the east coast with Cass/Hokitika via the Southern Alps. It is mostly two lane, with some single-lane bridges north of Springfield.a)Give fivepossible Level of Service (LOS) statements forthe State Highway 73 connection. b)Choose 3LOSfrom a)and develop at least two different Performance Measures(PM)using SMARTERfor eachselectedLOS.c)Give a few(2 or 3)possible projectsthatcan improve the LOS andbe monitored by the (PM)developed in b) above. Problem 2:AHP Decision Process Suppose that the Christchurch City Council (CCC)identified that theyrequire a new bridge to be constructed. CCC asks consultantsto deliver a range of options. The options are shown in Table 1. The Council has completed the following pairwisecomparisons as shown inTables 2 –6. a)For each of the tables (2 –6) use the pair-wise comparisons to identify the Council’spriority.b)Following the example in lectures, find the consistency ratio (CR) and determineif Tables 2-6 areconsistent.Make changes as appropriate if needed.c)Ifa criterion matrix is notconsistentwhat would youdo to solve this?d)Following the example in lectures use AHP to compare the sixbridge options given in Table 1. i)Which bridge shows the highest benefit according to youranalysis?ii)Complete a Benefit-Costanalysis following the examples in lectures.
