QUESTION ASSIGNMENT 2

In an urban transport study, a city is divided into six zones as shown in Figure 1. The

summarized land use data is given in Table 1.

Production rate of the residential unit is 1.9 trips per hour and attraction rate of the commercial

premises is 3.25 trips per 100 sq. meter floor area.

a) Compute the production and attraction of each zone.

b) Balance the production and the attraction.

c) Compute O-D trip matrix for the city.

d) Sketch the trip interchanges
