TABLE 5 A Sample Conditional Probability Table (Version 2)

Excel | CSV

Land uses and vehicles					Mode choices
No. drivers	Vehicle count	% medium residential	% high residential	Probability motorized trip	Probability nonmotorized trip	Probability transit trip
1	0	10	50	21	35	43
2	2	10	50	70	15	15
2	0	20	30	20	35	45
1	1	10	10	95	0	5
1	1	20	80	20	35	45

Notes: The algorithm properly finds that for those cases where drivers have a license but not a vehicle at their disposal, the probabilities of motorized trips are low. When a private vehicle is available, the probabilities of motorized trips are high but only if associated with small percentages of high residential land use.
