A simple work mode choice model is estimated from data in a small urban area to determine the probabilities of individual travelers selecting various modes. The mode choices include auto-drive alone (DL), auto-shared ride (SR) and bus (B), and the utility functions are estimated as: UOL = 2.2 -0.2 (costou) - 0.03 (travel timeou) USR = 0.8 -0.2 (costs) - 0.03 (travel times) UB = -0.2 (costs) - 0.01 (travel times) Where cost is in dollars and time is in minutes. Between a residential area and an industrial complex, 6000 workers depart for work during the peak hour. For all workers, the cost of driving an auto-drive alone (DL) is $ 6 with a travel time of 10 minutes the cost of driving an auto-shared ride (SR) is $ 3 with a travel time of 10 minutes. The bus fare is $1 with a travel time of 15 minutes. calculate the Prob. (BUS). Select one: O a. 0.134 O b.0.167 O c.0.367 O d. 0.194
