Example

The base year trip matrix for a study area consisting of three zones is given below.

	1	2	3	$o_i$
1	20	30	28	78
2	36	32	24	92
3	22	34	26	82
$d_j$	88	96	78	252

The productions from the zone 1,2 and 3 for the horizon year is expected to grow to 98, 106, and 122 respectively. The attractions from these zones are expected to increase to 102, 118, 106 respectively. Compute the trip matrix for the horizon year using doubly constrained growth factor model using Furness method.
