Impact of Shared Bus on Campus Travel and Space Optimization Based on Activity Travel Behavior

Journal of Advanced Transportation, 2021
Based on the travel analysis of students in the Jiulonghu campus, this paper constructs a small-scale shared bus in the campus, explores the impact of shared traffic on campus travel, promotes the optimization design of campus space environment, and ...

Finding Most Reliable Path With Extended Shifted Lognormal Distribution

IEEE Access, 2018
Travel time uncertainty may cause late arrival and impose a high penalty on travelers. There is a growing interest in modeling travel time uncertainty to optimize the reliability of travel time at the path and network level. Real data analysis finds that

The impact of travel time on geographic distribution of dialysis patients. [PDF]

PLoS ONE, 2012
BACKGROUNDS: The geographic disparity of prevalence rates among dialysis patients is unclear. We evaluate the association between travel time to dialysis facilities and prevalence rates of dialysis patients living in 1,867 census areas of Hiroshima ...

Rapid variability in the synchrotron self Compton model for blazars [PDF]

, 1998
Blazars are characterized by large amplitude and fast variability, indicating that the electron distribution is rapidly changing, often on time scales shorter than the light crossing time.

Travel time optimization on multi-AGV routing by reverse annealing [PDF]

Scientific Reports, 2022
Quantum annealing has been actively researched since D-Wave Systems produced the first commercial machine in 2011. Controlling a large fleet of automated guided vehicles is one of the real-world applications utilizing quantum annealing. In this study, we

Heterogeneous Data Fusion Method to Estimate Travel Time Distributions in Congested Road Networks

Sensors, 2017
Travel times in congested urban road networks are highly stochastic. Provision of travel time distribution information, including both mean and variance, can be very useful for travelers to make reliable path choice decisions to ensure higher probability

Consequences of mixing assumptions for time‐variable travel time distributions

Hydrological Processes, 2014
AbstractThe current generation of catchment travel time distribution (TTD) research, integrating nearly three decades of work since publication of Water's Journey from Rain to Stream, seeks to represent the full distribution in catchment travel times and its temporal variability. Here, we compare conceptualizations of increasing complexity with regards

Modelling Travel Time Reliability with the Burr Distribution

Procedia - Social and Behavioral Sciences, 2012
AbstractThis paper suggests the Burr distribution as a useful statistical model to represent travel time reliability through studies of the day-to-day variability in travel times on journeys in urban areas. This distribution has a flexible shape and the ability to describe the very long upper tails (and hence significant skewness) seen in observed ...

Distribution-free travel time reliability assessment with probability inequalities [PDF]

, 2011
An assumption that pervades the current transportation system reliability assessment literature is that probability distributions of the sources of uncertainty are known explicitly. However, this distribution may be unavailable (inaccurate) in reality as

On the minimal travel time needed to collect n items on a circle [PDF]

, 2004
Consider n items located randomly on a circle of length 1. The locations of the items are assumed to be independent and uniformly distributed on [0,1). A picker starts at point 0 and has to collect all n items by moving along the circle at unit speed in ...
