The studies assessed engineering-based behavioral interventions to increase the frequency of drivers' seat belt use.
It is shown that as subjects' subjective discomfort increases, the frequency of subjects' seat fidgets and movements increases congruently.
The resonance frequency of the seat decreased with increases in the magnitude of the vibration excitation and increased when subjects made contact with the backrest.
The average frequency of switches from seated to standing/walking or vice versa (FREQ1) was 10.4 per hour, females having on average 9.9 shifts per hour and males 11.5 (p = 0.090) (Table 2; Figure 2).
However, the resulting frequencies are coherent with the resonance frequencies of the seated human body [ 27, 32].
Then last week the Straphangers Campaign issued a report concluding that the Q line, which runs between Long Island City, Queens, and Brighton Beach, Brooklyn, is now the city's best in terms of cleanliness, availability of seats and frequency of trains.
The strongest predictor of both the frequency of the principal resonance in seat transmissibility and the seat transmissibility at resonance was subject age, with other factors having only marginal effects.
This time, Mr. Russianoff said, that comparison was impossible because New York City Transit, over the protests of some riders' advocates, changed the way it calculates some performance categories like seat availability, frequency of service and announcements.
It also showed that the frequency of service, number of transfers, seat availability, walking time to the transit stop and fare information are among the significant information types that commuters desire.
Optimisation variables are bus fare, congestion toll, bus frequency, bus size, fare collection system, bus boarding policy and the number of seats inside buses.
