OKI/MVRPC Travel Demand Model – Version 6.0Table 4-3 Logsum CoefficientsLogsum CoefficientProposed CurrentModel 6.0 Model 5.4Shared Ride 0.55 0.20Auto Submodes 0.85 0.80Transit Submodes 0.85 0.50Transit Access 0.55 0.30The final HBW utility expressions to be used in model application are listed below. In theseequations, all times are expressed in minutes and all costs are expressed in 1995 cents. "LB"stands for local bus and "EB" stands for express bus. The "K??? TM " terms are the mode specificconstants, stratified by time period (T) and market segment (M). Please refer to Section 7 forthe constants' final, calibrated values. Note that parking and auto operating costs are not sharedamong a vehicle's occupants, consistent with the finding that most carpools are composed ofmembers of the same household. Note also that these utility expressions, unlike the choice setused for model estimation, do differentiate between local and express bus, as well as betweenpark&ride vs. kiss&ride transit access.In model application, utilities corresponding to lower level choices are divided by the appropriatelogsum coefficients. Hence, U(drive-alone) is divided by 0.85, while all the other utilities aredivided by the product (0.85*0.55).The final HBU utility expressions are identical to the HBW utility functions, with the exception ofthe mode-specific constants, which were specifically calibrated for HBU mode share data (pleasesee Section 7).• U(drive-alone) TM = -0.0248 * (highway travel time + terminal parking time) +-0.0021 * (parking cost + auto operating cost) +KDA TM• U(share-ride 2) TM = -0.0248 * (highway travel time + terminal parking time) +-0.0021 * (parking cost + auto operating cost)• U(share-ride 3+) TM = -0.0248 * (highway travel time + terminal parking time) +-0.0021 * (parking cost + auto operating cost) +K3P TM• U(LB,walk) TM = -0.0248 * in-vehicle time +-0.0876 * (centroid walk time + transfer walk time) +-0.0409 * first wait time +-0.0461 * transfer wait time +-0.0021 * fare +KLBW TM• U(LB, p&r) TM = -0.0248 * (in-vehicle time + drive access time) +-0.0876 * (centroid walk time + transfer walk time) +-0.0409 * first wait time +-0.0461 * transfer wait time +-0.0021 * (fare + p&r park cost + access auto oper. cost) +KLBP TMMode Choice - Home-Based Work Model Estimation 21
