In this paper, we focus on two-dimensional connectivity in sparse vehicular ad hoc networks (VANETs). In this respect, we find thresholds for the arrival rates of vehicles at entrances of a block of streets such that the connectivity is guaranteed for any desired probability. To this end, we exploit a mobility model recently proposed for sparse VANETs, based on BCMP open queueing networks and s...

background to get more precise responses when gathering information about sensitive topics such as drug use, it is important to use the most optimal method. objectives this study was carried out to address the impact of three interview methods (street-based, household, and telephone interviews) on response pattern to sensitive and non-sensitive questions in terms of participation, disclosure an...

Network connectivity is an important aspect of the built environment. However, it rarely captures attention decision-makers while implementing pedestrian projects. In recent years, Space-Syntax (SS) analysis gaining popularity among researchers due to its ability clearly demonstrate topological configuration a physical network. This research carries out 297 links across three networks in Varana...

Traffic flow characterizes vitality in commercial clusters, and the accurate prediction of traffic based on street network has significant implications for planning regulation clusters. However, existing studies are limited by certain problems, such as difficulty obtaining data carrying out technical methods. The purpose this study is to use urban physical so quickly effectively estimate This t...

The health of patients with chronic diseases is affected not only by factors such as eating and living habits, but also the neighborhood built environment, travel conditions. Using 18 blocks in main urban area Changshu, China, we performed structural equation modelling, to explore relationships between commuting patterns diseases, patient health. We first divided into four categories—walking/bi...
