Travel time in minutes

There are 4000 jobs in industrial area X and 5000 in industrial estate Y. It is known that the attraction between zones is inversely proportional to the square of journey times. Calculate and tabulate inter zone trips for journeys from home to work using gravity model.

OR

What are the advantages and disadvantages of growth factor methods?

A new bypass is to be constructed at a busy city. The length of bypass will be 7.5 km and the length of the existing road is 8 km. The cost of the project is likely to be Rs.10,000,000. The speed of the traffic through the town is 48 kmph. And the present traffic is 800 vph. The predicted traffic after completion of project is 8500 vehicles/day out of which 55% will use bypass. It is computed if the bypass is not built, the traffic through the city will move at a speed of 42 kmph due to increased traffic. If the bypass is built the traffic on the bypass will be 80 kmph and that through the city will be 55 kmph. The travel costs for different speeds are 42 kmph, Rs.3.50/-, 55 kmph-Rs.3.40/- and 80 kmph-Rs.3.1/-. It is expected that the cost of construction of the bypass will bring down the accident rate from 1.8 per million vehicle km on the existing route to 0.5 per million vehicle km on the bypass. The cost of accident can be taken as Rs.50,000 and the maintenance cost per km is Rs.25,000/-. Compute the first year of return. Justify the project based on the minimum 50% return in first year.
