8C H A P T E R 2 Current practice in regional travel forecasting models typically considers the effects of travel times, wait times, frequencies, travel costs, and transfers when evaluating the benefits of transit services and estimating ridership. In many cases, however, models in metropolitan areas with existing rail services require large adjustments to replicated observed ridership patterns.

This example in Figure 2 provides only one glimpse into a complex survey, but serves to provide context for similar experimental survey methods.

12 Characteristics of Premium Transit Services that Affect Choice of Mode Effects on Awareness and Consideration of Transit Options The next potential contribution of non-traditional attributes involves traveler awareness of individual transit options and the degree to which travelers are willing to consider using these options. Inclusion of awareness and consideration in travel forecasting models is a relatively new concept.

Important Non-Traditional Transit Attributes 13 Key Findings Three key findings relate to travelers' awareness and consideration of transit options: 1. Many travelers are not aware of, nor do they consider, transit options that travel models represent as available for their trip.

14 Characteristics of Premium Transit Services that Affect Choice of Mode This research focused primarily on key findings related to the importance of premium service characteristics and their effect on awareness and consideration, as opposed to broader modeling considerations that go beyond service characteristics. Research Methods Questions about awareness and consideration of transit alternatives were included in the surveys for all three cities surveyed.

One primary question for these models is whether representing a traveler's awareness and consideration of transit will improve the ability of the mode choice model to explain travel behavior.

For example, more respondents from Salt Lake City indicated that they are willing to increase the frequency of transit usage than did respondents from Charlotte and Chicago.

20 Characteristics of Premium Transit Services that Affect Choice of Mode Research Results Table 4 presents the equivalent minutes of in-vehicle travel time for latent variables in the mode choice models. Most of the latent variables reflect large impacts on the choice of transit versus auto, but only few differences between the choice of bus and rail.

Important Non-Traditional Transit Attributes 21 When comparing modal availability predicted by network path-building models, travelers are more likely to report rail service being available than bus service. This may be because bus systems are more complex than train systems and bus stops are less visible than train stations.
