答案 The following report will look into difference in the numbers of cars of several categories based on the number of occupants before and after the implementation of the Share-a-Ride program. The figures were collected by the Plant Security Department which surveyed the cars arriving in the car park on two Thursdays. Before the program began, about two thirds of the cars (1621) entering the car park were occupied by only one person. In the descending of number, there were 432 cars with two occupants, 121 cars with three occupants, 108 cars with more than 4 occupants and 57 cars with 4 occupants. One week after the program started, the number of cars with one occupant was reduced by more than half, counting for about one third of the cars surveyed. In the meanwhile, numbers of cars with two or more than two occupants increased substantially, since employees who used to drive a car alone joined each other or others who shared cars with colleagues. It should also be noted that the total number of cars reduced from 2339 to 2084. To close, the number of cars parked at the company’s parking lots was reduced due to the Share-a-Ride program. More people chose to share a car with another colleague in consequence. However, still relatively few people rede in cars with three or more occupants, which demanded the attention of file company.
