Trip Distribution ►Trip Distribution is the process by which trip productions are matched to trip attractions to create a trip table of the number of trips between each zone pair in the network. FSUTMS--CUBE MODELING TRAINING SERIES 5 Gravity Model ►A mathematical model of trip destinations based on the premise that trips produced in any given TAZ will distribute themselves in accordance with the distance between TAZs and the attractions they offer ►The Gravity Model parallels Newton’s s Law of Gravity = M a Fgravity G 2 r M b FSUTMS--CUBE MODELING TRAINING SERIES 6 6-3
Gravity Model Equation T ij = P i × n ∑ ( A ) j Ftij K ij j = 1 A j F tij K ij where: Tij = Trips from zone i to zone j Pi = Total trips sent from zone i Aj = Total trips received by zone j Ftij = Impedance (time/distance) between zone i and zone j Kij = Socioeconomic adjustment factor for interchanges n = Number of analysis zones FSUTMS--CUBE MODELING TRAINING SERIES 7 Friction Factors ►Friction Factors (travel time factors, “ff” factors) are Impedance-Dependent Factors Used in the Gravity Model ►Friction Factors are: Generated from household survey data Borrowed from another study FF for work can be generated from Census Journey-to to-Work FF for internal-external external trips can potentially be generated from roadside surveys FSUTMS--CUBE MODELING TRAINING SERIES 8 6-4
