A small town has two residential zones, A and B producing 900 and 600 work trips respectively. Zones C, D and E are work opportunity zones attraction 900,400 and 200 trips. The travel times between the zones and actual obsrved trips are as shown in the attachment below;
A large retirement village has a total retail employment of 120. All 1600 of the households in this village consist of
two nonworking family members with household income of $20,000. Assuming that shopping and
social/recreational trip rates both peak during the same hour (for exposition purposes), predict the total number
of peak-hour trips generated by this village using the trip generation models of Example Problems 1 and 2.
to no congestion on the road further downstream of the railway grade crossing.
QUESTION 5:
Consider trip distribution within 5 zones in an area. The total trip production from zone 1 is
1000. The travel times from zone 1 to zones 2, 3, 4 and 5 are 5, 10, 20, and 30 minutes,
respectively. The trip attraction to zones 2, 3, 4 and 5 are 50, 200, 75, and 450, respectively.
Assume that the number of trips produced from zone 1 to zones 2, 3, 4 and 5 is inversely
proportional to the inter-zonal travel time.
(a) Estimate the number of trips from zone 1 to zones 2, 3, 4 and 5 using the gravity model.
(b) Assume that the future trip production from zone I will increase to 1,250 and the future trip
attraction to zones 2, 3, 4 and 5 will increase to 100, 225, 100, and 600, respectively. Predict
the number of trips from zone 1 to zones 2, 3, 4 and 5. The inter-zonal travel times remain
the same.
(c) Compare the number of trips from zone 1 to each destination zone between (a) and (b).

- A model for non-work related trips has been developed by the Texas Department of Transportation for Wheeler, Texas. The model is based on the number of trips per household: Number of peak-hour vehicle-based social trips per household = 0.04+0.018*(household size) + 0.009*(annual household income in thousands of dollars) + 0.16*(number of nonworking household members) For the northeast section of Wheeler, the average household has six members and an annual income of $50,000.
