Estimation of ridership on a new transit system in an area where no comparable service existed before is a difficult task of transit planning. Traditional modal split models cannot be used in these cases, because no data or basis for developing a new model or adjusting a “borrowed” model are available. One of the techniques which can be used in this type of situation, is to perform a “concept test” based on public opinion. This approach, however, is plagued with the phenomenon of non-commitment bias of interviewees, and tends to overestimate the ridership. A new fixed route and fixed schedule transit service in Johnson City in Tennessee provided a rare opportunity to perform an investigation on the non-commitment bias through “before” and “after” surveys. The analysis of the non-commitment and actual responses of a sample of residents revealed substantial bias. Overall, the non-commitment ridership estimate was about twice (100% greater than) the actual ridership.:It was also observed that the bias was higher for persons owning automobiles, and for work and shopping trips. 相似文献

An exploratory analysis of commuters' activity and travel patterns was carried out using activity-based travel survey data
collected in the Washington, DC metropolitan area to investigate and estimate relationships among socio-demographics, activity
participation, and travel behavior. Structural equations modeling methodology was adopted to determine the structural relationships
among commuters' demographics, activity patterns, trip generation, and trip chaining information. Three types of structural
equations model systems were estimated: one that models relationships between travel and activity participation, another that
captures trade-offs between in-home and out-of-home activity durations, and a third that models the generation of complex
work trip chains. The model estimation results show that strong relationships do exist among commuters' socio-demographic
characteristics, activity engagement information, and travel behavior. The finding that significant trade-offs exist between
in-home and out-of-home activity participation is noteworthy in the context of in-home vs. out-of-home substitution effects.
Virtually all of the results obtained in this paper corroborate earlier findings reported in the literature regarding relationships
among time use, activity participation, and travel.
