Viewpoint invariant pedestrian recognition is an important yet under-addressed problem in computer vision. This is likely due to the difficulty in matching two objects with unknown viewpoint and pose. This paper presents a method of performing viewpoint invariant pedestrian recognition using an efficiently and intelligently designed object representation, the ensemble of localized features (ELF...

Crowds are a quite usual experience in everyday life. They are mostly safe but, in some cases, can be dangerous. Understanding competitive egress behaviours can be helpful in avoiding tragic events: effective egress models are useful both in designing large venues and in calculating their working conditions during emergencies. The simulation of pedestrian motions within an area in the presence ...

The main objective of the study was to verify effectiveness active pedestrian crossings equipped with flashing lights activated automatically by detected pedestrians. A pilot conducted in two sites, where speed profiles vehicles over distance 30 m before crossing were analyzed. produced promising results terms reducing vehicle speeds so next investigated four other unsignalized crossings. They ...

In the New Normal era of “Living with COVID-19”, we need a measure safety street spaces. Social distancing during pandemic is considered an effective measure, but current binary threshold approach to social clearly inadequate for evaluating and monitoring risk infection on urban streets. This study propose indicator that can quantitatively evaluate level exposure viral pedestrians using streets...

this article is an attempt to study the development compatibility between pedestrian spaces of bazaar and tarbiat pedestrian malls in tabriz. the importance of this issue is due to the subject that today following the discussions on human development and environmental conditions, pedestrian spaces have been taken into consideration by planners and designers as one of the important strategies of...

Pedestrians are the most vulnerable road users. For evaluating and modifying pedestrian safety in unsignalized crosswalks,the first important issue is to identify and explore factors affecting the interaction behavior of pedestrians andvehicles in conflict areas. By analyzing those factors and determining how they affect road user's behavior, we canrepresent the plans and proc...

In today’s highly regulated cities, a conspicuous pattern of marginal open space has emerged between buildings and streets. With rapid population growth, different activities are also emerging in the spaces, particularly cities developing countries. This study explores informal use spaces along residential streets Ile-Ife, Nigeria, to identify physical planning implications. The data for this w...
