SECTION A QUESTION 1 (10 marks) Respond briefly to the following with the aid of examples/diagrams as appropriate: (a) The total interstate freight transport task in Australia is forecast to increase significantly in the next 15 years. (i) What are the main reasons for the low market shares of rail freight compared to road freight movements? (2 marks) (ii) What are the implications of that increase in terms of investment needs for rail and road corridors between the major capital cities? (2 marks) (b) List three of the main issues facing transport and land use planners in South East Queensland when dealing with the expected growth in population. Discuss briefly why you think those issues are important. (2 marks) (c) The ‘base—case’ in cost-benefit analysis needs to be defined at the outset. What do you understand by ‘base-case’? Why is it important to make sure that the base-case is defined fairly and accurately when conduction a cost-benefit analysis for a transport project? (2 marks) (d) Define 'discounting' in the context of cost-benefit analysis. Why are costs and benefits discounted to the base year in cost-benefit analysis? (2 marks) QUESTION 2 (7 marks) Respond briefly to the following with the aid of examples/diagrams as appropriate: (a) Accessibility is a concept useful to measure the performance of the transport system. (i) How can we calculate the Accessibility Index for a traffic analysis zone with respect to employment opportunities in the whole study area? (2 marks) (ii) What are two ways to improve the accessibility of residents of a zone, with respect to employment opportunities? (2 marks) (b) The trip distribution stage of the 4—step transport modelling process relies on three main inputs. (i) What are those inputs if a gravity model is being used? (2 marks) (ii) What data needs to be collected for the calibration of a gravity model? (1 mark) END OF SECTION A CEB508T1.041 cont/... 2 SECTION B QUESTION 3 15 marks) Respond briefly to the following with the aid of examples/diagrams as appropriate: (a) With the aid of an example describe how the 4-step process may be used to estimate traffic impacts in a development’s impact assessment. You may assume that the development is located on the south side of a sub—arterial road and may be granted all-movements access. (3 marks) (b) Explain the purpose of road hierarchy. With the aid of examples explain how road hierarchy can be used to manage access and parking in an urban road network. (2 marks) QUESTION 4 (8 marks) For each question select the most correct response: (You may use your work book for calculations and working. However you must clearly identify in your workbook your selected option number as your response to each sub-question.) (a) Which of the following is not true in describing the attributes of urban taxi application in Australia (1 mark): (i) Taxis ll niche time-critical and poor—transit-coverage markets (ii) Taxis are generally subsidised by government as they do not cover their costs at the fare box (iii) Taxis are commonly operated as owner—operator businesses (iv) Maxi-taxis may be deployed as community transit services due to economy of scale (v) The cost of use of access infrastructure by taxis is partly recovered through licensing fees (b) Which of the following is not true in describing the attributes of urban heavy rail public transport in Australia (1 mark): (i) Rail systems are mostly limited to mid-size to large size cities (ii) Many systems use track infrastructure originally constructed for freight movement (iii) Stop spacing is generally higher than for other public transport modes to improve speeds; as such passengers are prepared to walk further (iv) Overall system coverage is generally greater than bus systems operating in the same city or service region (v) It is common practice to direct feeder buses to strategic rail stations to achieve better modal integration and system efficiency (0) Which of the following parameters does not influence bus facility vehicle capacity (1 mark): (i) Signalised intersection approach green time ratio (ii) Loading area design (iii) Bus lane type (iv) Bus floor-plan (V) None of the above ((1) Select which of the following best describes a “level of service C” condition for Service Frequency of an urban fixed route transit service, according to the transit quality of service framework (1 mark): CEBSOST1.041 cont]... (i) Passenger’s don’t need schedules (ii) Maximum desirable time to wait if bus/train service is missed (iii) Service unattractive to choice riders (iv) Service unattractive to all riders (v) LOS C frequency may vary by time of day or week (e) Select which of the following Load Factor ranges (p/seat) corresponds to a “maximum schedule load” condition, according to the transit quality of service framework (1 mark): (i) 1.01—1.25 (ii) 1.01—2.00 (iii) 1.26-1.50 (iv) 2.01-3.00 (v) 0.76—1.00 (1) Select which of the following is the correct rail line peak direction person capacity (p/h) given the following critical station and train parameters: two platforms and two separate tracks peak direction, station close—in time 525, dwell time 25s, operating margin 303, peak hour factor 0.85, train service capacity 6.9p/m, train consist length 145m (3 marks): Note CL = 3600 t: + I‘d +tom (i) 51,890 (ii) 55,664 END OF SECTION B END OF PAPER CEB508T1.041 ...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
