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.
