7 M

Solve any two question from Q4(a), Q4(b) & Q4(c), Q4(d)
4 (a) Write short note on multiple linear regression analysis. Also discuss its assumptions.
7 M
4 (b) The total trips produced in and attracted to the three different zones X, Y and Z of a survey area in the design year are as follow:
The trips between two zones are inversely proportional to the second power of the travel time between zones, which is uniformly 30 minutes. If the trip interchange between zones Y and Z is known to be 600, Calculate the trip interchange between zones X and Y, X and Z, Y and X, Z and Y.
Zones Trips Produced Trips attracted
X 3400 2500
Y 4000 2200
Z 4000 3500
