Transportation engineering Problem 4 (30 points)It is known that 4000 automobile trips are generated in a large residential area from Noon to 1 PM onSaturdays for shopping purposes. Four major shopping centers have the following characteristics:Shopping Center-2314Distance from residential areaCommercial floor space(mi)(thousands of feet-square)2.42004.61505.03008.7600a) If a logit model is estimated with coefficients of -0.543 for distance and 0.0165 for commercial floorspace, how many shopping trips will be made to each of the four shopping centers?b) Suppose that shopping center 3 goes out of business and shopping center 2 is expanded to 450, 000square footage of commercial space. What would be the new distribution of the 4000 Saturdayafternoon shopping trips?c) If shopping center 3 is closed how much commercial floor space is needed in shopping centers 1 and2 to ensure that each of them has the same probability of being selected as shopping center 4?

land-use zone consists of 2000 single-family homes, 520 apartment units, and 3 hotels with 600 rooms each. Calculate the daily vehicular traffic generated by this zone, using the following equations: ts = 5+ 7.35US, ta = 7+ 6.25Ua = 2 + 12.00n t₁ = where the subscripts s, a, and h refer to homes, apartments, and hotels, respectively, and t and U refer to trips and housing units, respectively. Why is there a significant difference in trip production among the units?
It is known that 4000 automobile trips are generated in a large residential area from noon to 1:00 P.M. on Saturdays for shopping purposes. Four major shopping centers have the following characteristics: Distance from Shopping Center Number Commercial Floor Space (in thousands of m^2) Residential Area (km) 4 20 15 3 30 4 14 60 If a logit model is estimated with coefficients -0.283 for distance and 0.172 for commercial space (in thousands of m^2), how many shopping trips will be made to each of the four shopping centers?

On a certain bus terminal, there are two terminals that can travels to the south. The number of passengers going to the south arriving in the terminal is 150 persons per minute, and the number of people can ride the bus is 100 per minute. Both arrival and departure rates can be assumed to be exponentially distributed. What is the probability having 0 ppassengers in the queue? a. 0.143b. 0.375c. 0.209d. 0.182

Give me right solution with clear calculations
A mode choice logit model is to be developed based on the following information. A surveyof travellers in an area with bus service found the following data:Model Parameter Auto BusX1, waiting time (min.) 0 10X2, travel time (min.) 20 35X3, parking time (min.) 5 0X4, out-of-pocket cost (cents) 225 100Ak, calibration constant _0.33 _0.27The following utility functions were calibrated based on an observed mode split of 84.9%private auto use and 15.1% bus use.Utility function: Uk = Ak -- 0.10 X1 - 0.13 X2 - 0.12 X3 - 0.0045 X4After implementing service improvements to the buses, the mode split changed to 81.6%private auto use and 18.4% bus use. Determine a value for the calibration constant for the busmode that reflects this shift in mode split.
