This paper studies the impact of service frequency and reliability on the choice of departure time and the travel cost … service reliability, as expected. It does not necessarily decrease with service frequency, however. We derive the value of … service headway (VoSH) and the value of service reliability (VoSR), which measure the marginal effect on the expected travel …

This paper extends the analysis of the value of mean travel time (VMTT) and day-to-day travel time variability (VTTV) from single, isolated trips to daily trip chains, considering the effects of flexibility in activity scheduling and within-day correlation of travel times. Using a multi-stage...

This paper derives a measure of travel time variability for travellers equipped with scheduling preferences defined in terms of time-varying utility rates, and who choose departure time optimally. The corresponding value of travel time variability is a constant that depends only on preference...

the reliability of travel times at the path and network level. This paper focuses on the analysis and optimization of … travel time (including stopped delays) Reliability on the Urban Road Network in Chennai. Specifically, two objectives are … investigated. The first objective involves the quantification of travel time reliability at the link and path level. In particular …

reliability (TTTR) and total travel time budget (TTTB) are two risk measures recently proposed for assessing transportation … reliability level. It is able to account for the tradeoff between planners’ risk-aversion attitude and the unacceptable risk …, which avoids the need of setting a too conservative reliability requirement in the TTTB to reduce the unacceptable risk. The …

The effectiveness of transit-based emergency evacuation highly depends on the location of pick-up facilities, resource allocation, and management. These facilities themselves are often subject to service disruptions during or after the emergency. This paper proposes a reliable emergency facility...
