Visual analysis of speed bumps using floating car dataset
ABSTRACT The analysis of traffic movements in urban populations is important for safety measures to control speed when the presence of pedestrians is high. Most of the studies in the traffic domain are directed towards statistical analyses of speed, also to measure the physical parameters of bumps on roads, and effect of speed-calming measures. However, less is known about the effectiveness of varying intervals between speed-calming measures and their influence on the driving behaviour of vehicles from a spatio-temporal perspective. To fill this gap and understand these aspects, in this research we propose visual analytics techniques. To explore the influence of the distance between bumps on speed change behaviour of vehicles in relation to the permitted speed limit, several use case studies were selected with the close cooperation of a traffic expert. The aim was first to study the influence of the speed bumps on speeding, and then establish any connection between speed bump intervals and vehicle speeding in the selected use cases. The results of our investigation did reveal minor differences and influence of a time aspect on traffic volume and speed development. Also, differences in actual speed of the vehicles in relation to the distance of installed bumps were detected.
期刊介绍:
The aim of this interdisciplinary and international journal is to provide a forum for the exchange of original ideas, techniques, designs and experiences in the rapidly growing field of location based services on networked mobile devices. It is intended to interest those who design, implement and deliver location based services in a wide range of contexts. Published research will span the field from location based computing and next-generation interfaces through telecom location architectures to business models and the social implications of this technology. The diversity of content echoes the extended nature of the chain of players required to make location based services a reality.
