Several studies and researches have shown that modern roundabouts are safe and effective as engineering countermeasures for traffic calming, and they are now widely used worldwide. The increasing use of roundabouts and, more recently, turbo and flower roundabouts, has induced a great variety of experiences in the field of intersection design, traffic safety, and capacity modeling. As for unsign...

In recent years, technologically advanced high-throughput techniques have been developed that replace, reduce or refine animal use in vaccine quality control tests. Following validation, these tests are slowly being accepted for use by international regulatory authorities. Because regulatory acceptance itself has not guaranteed that approved humane methods are adopted by manufacturers, various ...

Process modeling is an emergent area of Information Systems research that is characterized through an abundance of conceptual work with little empirical research. To fill this gap, this paper reports on the development and validation of an instrument to measure user acceptance of process modeling grammars. We advance an extended model for a multi-stage measurement instrument development procedu...

The purpose of this article is to highlight the limitations and drawbacks of existing knowledge about e-service quality and e-service user acceptance. To overcome these limitations we will propose some solutions. An extensive review of relevant literature has shown that a lot of research has already been conducted in this field. However, there is still a gap between the percentage of existing e...

To properly integrate information & communication technologies (ICTs) in higher educational institutes (HEIs) of Pakistan demands factors which relate with their usage, acceptance, adoption, and diffusion need be analyzed through some appropriate statistical tests before their implementation at ground level. This study measures critical factors such as ZPD (zone of proximal development) gap, di...

Pedestrian-vehicle conflicts are considered as one of the most common safety problems at signalized intersections. The threat to pedestrian safety is mainly related to the interaction with turning vehicles, especially left-turners (left-hand traffic). This paper aims at analyzing the lag/gap acceptance behavior of left-turning vehicles considering pedestrian movement at signalized crosswalks. F...

This paper documents a special application of a video-image system (AUTOSCOPE) to track main-street through movement vehicles and measure their individual speeds at two-way stop-controlled intersections. The initial objective of this application was to find an automated means to collect vehicle speeds at unsignalized intersections for the purpose of analyzing a driver’s gap-acceptance character...

This research was set to examine the factors influencing the willingness and the likelihood of Ghanaians to accept the capitation payment system under the National Health Insurance Scheme. Data was collected through the random sampling method in all the ten regions of Ghana. A probit estimation with marginal effects was adopted to examine the factors influencing the willingness and the likeliho...

E-bikes, which have the potential to reach higher speed levels than conventional bicycles, but look basically the same, are suspected to be at a higher crash risk than such conventional bicycles. Other road users might misjudge the time remaining before the approaching bicycle arrives (time to arrival, TTA) and accept unsafe gaps (e.g. for turning manoeuvres) as a result of this combination of ...
