Access and egress are essential components to the convenience and availability, and thus the success, of a public transport system. Initiatives aimed at improving access and egress could potentially make a significant reduction in trip time. Accurate estimates of access and egress times, however, are often not available. This study uses data from a comprehensive travel-activity diary to investigate access and egress times and the proportion of access and egress time to total trip time as indicators of public transportation availability and use. The results suggest that access and egress times are a function of access and egress modes and trip orientation rather than of sociodemographic characteristics. Land use has a different impact on access and egress and in both cases the relationship seems nonlinear. Access and egress times increase with increasing trip time, however, the increase is not as strong as line-haul time and as a result the interconnectivity ratio (access and egress time as a proportion of total trip time) declines as trip time increases. For most multimodal trips, the ratio falls within a modest range of 0.2-0.5. These results are potentially useful for estimating travel time and disaggregated mode choice models.
