Many theorists believe that transit service mode has little influence on consumer choice between automobile and transit travel. Others believe that they have noted a modal effect in which rail transitattracts higher ridership than does bus when other factors are about equal. Given environmental concerns and the large investment needed for guided transit, a better understanding of this issue is essential, especially for congested areas. A consideration of the history of automobile and transit travel in the united states can be helpfulin comprehending the nature of the problem. After world war ii, availability of vehicles, fuel, and tires spurred growth of both private automobile use and use of buses for transit. Analyses of the effects of both this growth and the improvements in rail systems that were added during the same period reveal that transit mode does indeed make a significant difference in the level of use of a transit facility. This factor must be included in future alternative analysis studies if reliable patronage determinations are to be made.
