The Hawkins study area is currently home to 80,000 residents and supports employment for the local community and surrounding regions of Brennertown (East of Hawkins) and Hargrove (South of Hawkins). The mayor of Hawkins, Mayor Kline, has asked the transport consultancy firm that you're employed at to provide forecasts of the travel demand across the community. Figure 1 presents the study area of Hawkins highlighting the key transport infrastructure. The primary highways connecting Hawkins with other regions are the Interstate Eleven (1-11), Interstate Twelve (1-12) and the Interstate Alpha (l-Alpha). The other labelled roads serve as important arterial roads and corridors within the region. Hawkins and surrounds are also serviced by a metro train public transport service. The three stations (Starcourt Mall Station, Hawkins Station and Hawkins Airport Station) within the study area are indicated in Figure 1. The CBD area of Hawkins is also highlighted (orange), signifying the key economic centre of the region. In order to forecast travel demand for the region, your consultancy must develop a 4-step travel model. Hawkins has been separated into the 4 zones presented in Figure 2 as a necessary step to generate and distribute trips throughout the region. The primary land uses of each of the zones are briefly described as follows: Zone 1: Contains the regional airport (Hawkins Airport) and a number of industrial complexes mixed with parkland. The land use density is relatively low throughout the zone with a relatively low residential population. This zone contains the interchange between l-Alpha and 1-12 as well as the complex intersection of Nancy Street and the 1-12. Zone 2: Mixed use zone with rural and industrial properties present on the northern half of the zone, while low to medium density residential properties exist near Wheeler Way. This zone contains the interchange between I-Alpha and I-11. • Zone 3: The main economic driver of Hawkins. Contains the CBD located at the north-western corner of the Zone and mixed high density land-use extends until the l- 11. East of the 1-11 is primarily low and medium density residential area with a number of parks along the highway. Zone 4: Low and medium density residential area with a major commercial development, "Starcourt Mall" (currently being expanded for completion in 2030). The development is expected to generate 5,000 jobs in the commercial and retail sector to help both the people of Hawkins as well as the neighbouring region of Hargrove. In addition to the expansion of Starcourt Mall, there is a major residential development, "Palace Arcade Hills", bounded by William Drive, Wheeler Way, Main Street and Joyce Street (highlighted in blue in Figure 1, within Zone 4). This is expected to provide 6,000 additional households in Hawkins by 2030. Type here to search 8: O W Ⓒ Not syncing 6 A Aộ oa) và ENG 9:14 PM 24/05/2022 x

Hawkins Council have conducted a observational trip generation survey of 25 residences as a proxy for the expected population in Palace Arcade Hills development (see Table 1) Table 1: Travel Survey Data (for trip generation model development) Observation Income (1) Household Size (H) Number of Vehicles Owned (V) # of weekday trips produced between 5am and 9am (T) 1 90000 3 1 2 45000 1 1 1 110000 5 1 3 100000 4 2 2 70000 3 10000 1 100000 2 50000 " 1 70000 " 1 90000 1 50000 1 wwwww 60000 1 45000 1 www. 60000 2 70000 2 80000 70000 60000 70000 10000 50000 wwwww 60000 55000 125000 5 55000 3 80000 4 65000 3 Type here to search L MO O 8: 2 3 4 5 6 6 19 7 4 8 0 9 10 11 12 13 14 15 16 17 18 19 19 20 zv 21 22 23 24 25 = 4 4 2 ² 2 ² 3 2 1 1 2 3 2 2 3 2 1 3 3 2 - 1 2 - 2 1 2 2 2 3 1 2 1 3 10 7 2 1 7 2 3 1 1 0 1 2 = 1 3 2 1 2 - 2 1 2 3 1 4 2 Ⓒ Not syncing 6 A W Aộ oa) và ENG 9:15 PM 24/05/2022 x

(2 marks) b) Upon completing the linear regression, what are the coefficients of the independent variables? Which variables are significant in the model? What is the goodness of fit of the model developed, is it a suitable model? Explain your answer using a statistical measure. (4 marks) c) Do the values of the coefficients align with the key principles underlying trip generation? Clearly justify your explanation. (4 marks) d) Based on the information provided to date and the process used to define the trip production model in part a), is this an appropriate model to use? Clearly justify your statement reflecting on the variables considered and data used.

Comment on the validity of the results. Do the zones of Hawkins attract more trips than they produce? Are the values obtained consistent with the population and land use described in the brief?

Assume all the values in Table 2 remain the same, except for the following changes: • There are an additional 6,000 households resulting from the Palace Arcade Hills development. The Starcourt Mall expansion will result in an additional 10,000 m² office space and 25,000 m² retail space. . The average household size increases in the following zones: o Zone 2: Household Size = 3.5 o Zone 3: Household Size = 2.5 Describe the impact of the proposed developments by considering the change in population, change in productions and attractions and the sections of the road network that will be face increasing congestion.
