4. The number of trips generated by each household h (Yh) in Zone A is given by the following household-level regression model: Yh=2.5+1.5 X₁ + 1.2 X2+ 1.0 X3....where, X₁ =Number of Adults (per household). X2 =Number of Cars in the household. X3 =Income in Thousands ($). a. What is the minimum number of trips made by a household based on the equation? b. For a zone labeled “A”, Table 1 provides total number of households classified by household size and number of cars. It is given that the average household income in this Zone is $55K. Compute the number of trips produced from this zone. Table 1: Household Composition for Zone A Number of cars Person per household per household 1 2 3 0 100 200 150 1 300 500 210 2 150 100 60

Density on a corridor was estimated to be 47 vehicles per mile using a snapshot from a flying drone. If the average space mean speed was calculated as 45 mph, then what is the average headway between vehicles? Report your answer in seconds up to two digits after the decimal.

Question 3 a) Explain the 'gravity model' adopted in trip distribution, and how that can be used to link land and transport planning. 100 50 50 b) Given an initial trip matrix t = with two origins and three 200 100 200 destinations. We also have a target trip generation from the two origins: 300 a = 600 and the trip attraction to the three destinations: b = [400 200 300]. Perform two iterations of Furness Procedure in order to adjust the trip matrix T such that the trip generation and attraction therein will match those specified.
