Fundamentals of Transportation/Trip Generation/Solution

 Problem: Planners have estimated the following models for the AM Peak Hour

$$ T_{O,i} = 1.5*H_i \,\!$$

$$ T_{D,j} = (1.5*E_{off,j}) + (1*E_{oth,j}) + (0.5*E_{ret,j}) \,\!$$

Where:

$$T_{O,i}\,\!$$ = Person Trips Originating in Zone $$i\,\!$$

$$T_{D,j}\,\!$$ = Person Trips Destined for Zone $$j\,\!$$

$$H_i\,\!$$ = Number of Households in Zone $$i\,\!$$

You are also given the following data

A. What are the number of person trips originating in and destined for each city?

B. Normalize the number of person trips so that the number of person trip origins = the number of person trip destinations. Assume the model for person trip origins is more accurate.

 Solution: A. What are the number of person trips originating in and destined for each city?

B. Normalize the number of person trips so that the number of person trip origins = the number of person trip destinations. Assume the model for person trip origins is more accurate.

Use: $$ \quad T_{D,j}^' = T_{D,j} \frac =  > T_{D,j} \frac = T_{D,j} *1.0204 \,\!$$
