In this paper we determine the relationship between developmental patterns and the incidence of traffic accidents. We evaluate the accident data for four intersections, which inhabit two different developmental typologies of the urban environment. Key-Words: urban core, sprawl development, arterial thorough fares, crash incidence, neighborhood scale.

The proliferation of sophisticated web technologies requires efficient tools to evaluate the performance of HTTP traffic under various conditions. In this paper, we present HTTP-Automated Evaluation (HTTP-AE) as a multi-user client-side framework for evaluating HTTP performance. The framework can be used to evaluate mechanisms, which improve HTTP performance. We present several case studies in ...

This memo explains how to use the Upgrade mechanism in HTTP/1.1 to initiate Transport Layer Security (TLS) over an existing TCP connection. This allows unsecured and secured HTTP traffic to share the same well known port (in this case, http: at 80 rather than https: at 443). It also enables "virtual hosting," so a single HTTP + TLS server can disambiguate traffic intended for several hostnames ...

This paper looks at Content-delivery networks (CDNs) originate a large fraction of Internet traffic; yet, due to how CDNs often perform traffic optimization, users aren't always assigned to the best servers for end-user performance and, in particular, suggests Provider-aided Distance Information System (PaDIS), which is a mechanism to rank client-host pairs based upon information such as RTT, b...

A Digital Twin is a digital replica of living or nonliving physical entity, and this emerging technology attracted extensive attention from different industries during the past decade. Although few studies have been conducted in transportation domain very recently, there no systematic research with holistic framework connecting various mobility entities together. In study, twin (MDT) developed,...

While WiMAX handoff characteristics and quality of service (QoS) provisioning have been explored by many network researchers, the effect of traffic type, node mobility and network size on WiMAX has not been fully explored yet. This paper therefore reports on a study of the impact of traffic type and node mobility on the performance of a typical mobile 802.16 WiMAX for varying network sizes. The...

Monitoring unused or dark IP addresses offers opportunities to extract useful information about both on-going and new attack patterns. In recent years, different techniques have been used to analyze such traffic including sequential analysis where a change in traffic behavior, for example change in mean, is used as an indication of malicious activity. Change points themselves say little about d...
