Milwaukee - Table 3.8 provides a more detailed account of the observed travel of the 57 Milwaukee subjects. The table summarizes travel during the weekday morning observation and the Friday/Saturday evening observation conducted during the suspension period. For the 3 subjects whose license was reinstated, the table also summarizes their travel during the observations conducted after reinstatement. After reinstatement, all 3 persons drove during the Friday/Saturday observation, and none were observed traveling during the weekday morning observation.

For the during-suspension observations, the results for the weekday morning and the evening observations did not differ dramatically. During the weekday morning observations, 16 persons drove and 5 persons used other transportation; during the evening observations, 18 persons drove and 3 persons used alternative transportation (Table 3.8). The 8 trips made with alternative transportation included subjects walking (2) or riding as passengers (6).
Information was gathered on the presence of passengers when subjects drove. For the 34 during-suspension driving trips, 24 drivers had no passengers, 4 transported adult passengers, 2 transported child passengers, and 4 transported both adult and child passengers.

Overall, when both during-suspension observation periods are considered, the travel patterns for the 57 Milwaukee subjects were as follows:

  • 23 subjects were not observed traveling during either observation period.

  • 23 subjects drove during one observation period and were not observed during the other period.

  • 4 subjects drove during both observation periods.

  • 3 subjects drove during one observation period and used alternative transportation during the other.

  • 3 subjects used alternative transportation during one observation period and did not travel during the other.

  • 1 subject used alternative transportation during both observation periods.

As noted previously, of the three Milwaukee subjects whose license was reinstated, two subjects drove during one of the during-suspension observation periods and during one of the post-reinstatement observation periods. The third subject did not travel during either during-suspension observation but drove during one post-reinstatement observation.

Bergen County - The detailed results for observed travel in Bergen County are provided in Table 3.9. The results show different patterns of travel between weekday mornings and evenings for the during-suspension observations. Of the 12 persons observed traveling during the weekday morning observation, 2 drove and 10 used alternative transportation. In contrast, of the 14 persons observed traveling during the evening observation, 7 drove and 7 used alternative transportation. Thus, the driving observed for the during-suspension observations was more likely to occur during the evening observations. For the post-suspension observations, of the 12 persons traveling during the weekday morning observation, 9 drove and 3 used alternative transportation. Of the 11 persons traveling during the evening observation, 10 drove.

The 17 during-suspension trips that involved alternative transportation included subjects riding as passengers (11), walking (3), and walking and riding a bus or train (3). With regard to passengers transported, only 1 of the 9 during-suspension driving trips involved the transportation of a passenger.

When both during-suspension observation periods are considered, the travel patterns for the 36 subjects observed were as follows:

  • 14 subjects were not observed traveling.

  • 13 subjects used alternative transportation during one observation and were not observed during the other.

  • 5 subjects drove during one observation and were not observed during the other.

  • 2 subjects used alternative transportation during one observation and drove during the other.

  • 1 subject used alternative transportation during both observations.

  • 1 subject drove during both observation periods.

Subjects' travel patterns were compared for the during-suspension and post-suspension observations for the 28 Bergen County subjects whose license was reinstated. Nine subjects did not drive during either of the during-suspension observation periods but drove during at least one post-reinstatement observation period. Three drove during one of the during-suspension periods and during both periods after reinstatement. Only one subject was observed driving during one of the during-suspension periods but not after reinstatement. Of the 8 subjects who did not have their license reinstated, 5 did not travel during either of the during-suspension observations, and 1 walked, 1 rode as a passenger, and 1 drove during one of the observations.
