Do note Table 3 presents ALL productions and attractions related to both local (within Hawkins) and non-local (outside of Hawkins) trips. Table 3: Productions and Attractions in each zone Zones 1 Productions Attractions 5,500 6,500 2 21,200 10,500 3 46,000 64,500 4 50,000 29,000 Table 4: Calibrated Friction Factors between each zone Zone 1 2 3 4 1 0.85 0.42 0.75 0.38 2 0.45 0.65 1.14 1.21 3 0.65 0.71 1.15 1.48 4 0.51 0.65 1.4 1.31 Table 5: Calibrated K-factors between each zone Zone 1 2 3 4 1 0.75 0.91 0.99 0.95 2 0.85 1.02 1.31 1.20 3 0.60 1.52 1.45 0.99 4 1.11 1.21 1.37 1.70 In addition to the above data, the following information describes the expected number of local trips that will be produced by and attracted to each zone within Hawkins • Zone 1: Only 1/4 of the trips produced in Zone 1 travels to Zones in Hawkins and 4,000 trips attracted to zone 1 are locally produced (by Zone 2, 3, 4). • Zone 2: Exactly 1/2 of the trips produced in Zone 2 travels to Zones in Hawkins and 6,000 trips are attracted from Zone 1, 3 and 4. • Zone 3: 14,000 trips produced in Zone 3 travel to Zones in Hawkins and 14,000 trips are also attracted to Zone 3 from the remaining local zones. • Zone 4: Only a small portion of trips produced in Zone 4 are expected to travel locally (just 20%) while 8,000 trips are attracted to Zone 4 from the other local zones.

Describe what this signifies terms of employment and education opportunities in Hawkins. (5 marks) b) What are the production and attraction values necessary to determine the local trip distribution (between the 4 zones identified in Figure 2) in Hawkins? Complete the following table template below to present your solution. Zones Local Total Total Local Productions Attractions Productions Attractions 1 5,500 6,500 2 21,200 10,500 3 46,000 64,500 4 50,000 29,000 (2 marks) c) Use the gravity model to distribute the AM peak morning trips for Hawkins to an accuracy of 1%. Present your converged trip distribution table with values rounded to the nearest whole number. Clearly describe the process, and assumptions made, while applying the gravity model. Does the converged origin-distribution matrix provide any information about mode choice within the four local zones? (8 marks) d) What Origin-Destination pairing (Zone-to-Zone) has the greatest travel demand during the morning peak period, is this a logical result? Provide a brief (half- page maximum) discussion on the potential transport impacts of the estimated distribution, referring to both the public and private transport network presented in Figure 1.
