Part 1 - Data and Sampling problem Consider an urban area where 100,000 people travel to work. Assume you possess the following information about them: (1) General information Mode Average number of cars per household 2.40 1.60 0.20 0.55 Family income ($1000/year) 120 60 Car Metro Bus Total 10 (ii) Population distribution Family income ($1000/year) Low (75) Total 63.6 0.0 Cars per household 2+ 15.9 3.7 2.4 22.0 Total 79.5 12.5 8.0 100.00 5.6 0.0 70.0 You are required to collect a sample of travellers to estimate a series of models (with a maximum of 8 parameters) which guarantee a negligible specification error if you have available at least 50 observations per parameter. You are also assured that if you take a 20% random sample of all travellers the error will be negligible and there will be no bias. Your problem is to calculate the total cost associated with each sampling method (random, stratified or choice-based) and recommend the best sampling method given the following information: Hourly cost of an interviewer. $2 per hour Questionnaire processing cost: $0.3 per form Time required to classify an interviewee: 4 min Time required completing an interview: 10 min You are also given the following table containing recommended choice-base sample sizes: % to be interviewed Subpopulation size 60,000 15 Your cost calculations need to be clearly explained. You need to submit an excel sheet including your calculations in an organized and easy to understand way alongside a document explaining your calculations and recommendation Part 2 - Applying travel demand modelling in the assessment of new transport infrastructure You are to clearly articulate in your Submission how you would apply travel demand modelling in the assessment of a proposal to build a new rail line from a Central Business District (CBD) to an international airport located 20km from the CBD and running express from the CBD terminal to the airport. Your Submission should consider aspects such as: Data Model formulation Model development Model application It is expected that your Submission will be between 750 and 1,000 words (excluding the refences). Your Submission will be graded based on its clear articulation of the approach application of travel demand modelling in the assessment of the new transport infrastructure and on the Submission quality, including English expression, structure and presentation, reference citation and listing etc. Part 1 - Data and Sampling problem Consider an urban area where 100,000 people travel to work.
