A city council wants to update its urban transport modelling system for an area with four traffic zones. It also has some budget to work on the roads and modes of transport from zone 1 to zone 4 and needs to find the details of mode and route choice for trips from zone 1 to zone 4 of the system to plan the upgrade. The council hired you to predict the trip production and trip attraction in its area, find trip distribution between different traffic zones.

Population (in thousand people)	Average yearly income (in thousand pounds)	Employment (in thousand people)	Land price (in thousand pounds per square meter)
Zone 1	181	31	65	2.7
Zone 2	441	41	44	3.1
Zone 3	300	24	135	2.5
Zone 4	250	43	193	4.1

Table1: Population, income, employment, and land price for each zone

(Do Not: Round the number of trips to the closest whole number of trips in your answer, for example, 2.4314 thousands vehicles will be 2431 veh.)

1. Calculated trip production and attraction for each zone and present it in a tabular format.

2. Calculated the trip rates between the four zones, i.e. trip distribution table.

3. Number of travellers per mode, from zone 1 to zone 4. In your report to the city council you need to interpret the meaning of the coefficients in the utility functions, how they affect utility and the final results (number of travellers). (Tips: For this task you need to calculate utilities for each mode. Calculate probability of each mode. Then calculated number of travellers for each mode.)

4. For route choice between the two routes available between zone 1 and zone 4, you need to consider car-mode trips and calculate traffic flow, corresponding travel time on each route, and total travel time for the designed traffic.
