Decision Trees as a Tool for Real-Time Travel Time Estimation on Highways

open access: yesCommunications, 2013
This paper presents a time travel estimation model based on a decision tree. Input parameter for travel time prediction is occupancy of detectors. The proposed model was tested on the most widely used arterial in Prague and also in the Czech Republic ...

Genetic Time Travel [PDF]

open access: yesGenetics, 2016
Abstract At its core, genetics is a historical discipline. Mutations are passed on from generation to generation and accumulate as a result of chance as well as of selection within and between populations and species. However, until recently, geneticists were confined to the study of present-day genetic variation and could only ...

Space, Time, and Time Travel [PDF]

open access: yesSSRN Electronic Journal, 2023
Newton supported the idea of absolute time, unlike Leibniz, for which time is only a relation between events and cannot be expressed independently, a statement in concordance with the relativity of space-time.  Eternalism claims that the past and the future exist in a real sense, going to the idea that time is a dimension similar to spatial dimensions,

Calculation of Theoretical Travel Time and Automatic Picking of Actual Travel Time in Seismic Data

open access: yesApplied Sciences, 2023
We used the ray tracing technique based on the IASP91 Earth model to calculate the travel times in order to identify the phases. This technique can calculate the travel times for the seismic phases in the conventional travel time tables.

Time, travel and infection [PDF]

open access: yesBritish Medical Bulletin, 2004
The collapse of geographical space over the last 200 years has had profound effects on the circulation of human populations and on the transfer of infectious diseases. Three examples are used to illustrate the process: (a) the impact of the switch from sail to steamships in importing measles into Fiji over a 40-year period; (b) changes in measles ...

Analyzing travel time distribution based on different travel time reliability patterns using probe vehicle data

open access: yesInternational Journal of Transportation Science and Technology, 2020
Travel time distribution (TTD) has been widely used to represent the traffic conditions on freeways and help to analyze travel time reliability (TTR).
