With the rapid increase in ride-hailing, a need to better understand and regulate industry arises. Conflicting results have been published by researchers policy makers regarding ride-hailing’s impact on congestion, public transit, other aspects of traffic systems. One obstacles studying ride-hailing is lack granular operational data over relatively long period time. An efficient system that can...

BACKGROUND Few studies have assessed the predictors of changes in commuting. This study investigated the associations between physical environmental characteristics and changes in active commuting. METHODS Adults from the population-based European Prospective Investigation into Cancer (EPIC)-Norfolk cohort self-reported commuting patterns in 2000 and 2007. Active commuters were defined as tho...

A \trip" is a triple (g; u; v) where g is, in general, a graph and u and v are nodes of that graph. The trip is from u to v on the graph g. For the special case that g is a tree (or even a string) we investigate ways of specifying and implementing sets of trips. The main result is that a regular set of trips, speciied as a regular tree language, can be implemented by a tree-walking automaton th...

Land use largely depends on the traffic policy of a city. The appearance e-scooters can greatly affect visual distribution transportation, and thus occupation land, primarily in central areas cities. E-scooters as shared micro-mobility service have become widespread worldwide since 2017. advent has made changes travel habits, especially parts big However, many issues are focused e-scooter mobil...

BACKGROUND The current study examined the associations between active commuting to school, cognitive performance, and academic achievement in Dutch adolescents. In addition, it was explored whether these associations were moderated by sex and mediated by depressive symptoms. METHODS Students in grades 7 and 9 (N = 270; mean age 13.4 years; 53% boys) were included. Active commuting to school w...

Many short trips are made by car, and replacing them with walking is a potential strategy to increase physical activity at the population level. The prevalence and correlates of walkable short car trips were examined among adults aged 18–84 years living in the state of Queensland, Australia. Participants (N1⁄414,481) reported their travel behaviors using a 24-h travel diary in the 2009 South Ea...

‎in a recent paper c‎. ‎miguel proved that the diameter of the commuting graph of the matrix ring $mathrm{m}_n(mathbb{r})$ is equal to $4$ if either $n=3$ or $ngeq5$‎. ‎but the case $n=4$ remained open‎, ‎since the diameter could be $4$ or $5$‎. ‎in this work we close the problem showing that also in this case the diameter is $4$.

INTRODUCTION The purpose of this study was to examine trends in walking for transportation among U.S. adults and youth for Healthy People 2010 objective 22-14. The objective calls for increasing the proportion of trips of 1 mile or less made by walking to 25% for adults and 50% for youth. National transportation surveys are used to track national health objectives, but data interpretation and c...
