Individual decisions for making trips Decision mode? Use discrete choice (multinomial logit model ) for each tour. C private = w 2 * in vehicle time + (perceived voc*distance)/(VOT*occupancy) C public = w 1 * walk time + w 2 * in vehicle time + w 3 *wait time + fare/VOT C walk = w 1 * walk time U mode i = a*C mode i where a is weight factor of cost by mode i Case study : Muang Phitsanulok Mode Split
