Pedestrian

Summary

A pedestrian is a person traveling on foot, whether walking or running. In modern times, the term usually refers to someone walking on a road or pavement, but this was not the case historically. Etymology The meaning of pedestrian is displayed with the morphemes ped- ('foot') and -ian ('characteristic of'). This word is derived from the Latin term pedester ('going on foot') and was first used (in English language) during the 18th century. It was originally used, and can still be used today, as an adjective meaning plain or dull. However, in this article it takes on its noun form and refers to someone who walks. The word pedestrian may have been used in middle French in the Recueil des Croniques et Anchiennes Istories de la Grant Bretaigne. History Pedestrianism Walking has always been the primary means of human locomotion. The first humans to migrate from Africa, about 60,000 years ago, walked. They walked along the coast of India to reach Australia. They walked

Pedestrian Destinations in Paléo Music Festival from Bluetooth Traces

Elisaveta Kondratieva

Can we guess the destinations of attendees in a music festival from Bluetooth traces collected by 10 people with smartphones used as antennas? This project analyzes an existing dataset of Bluetooth traces from Paléo music festival in Nyon, Switzerland. The goal of the project is to follow Paléo festival attendees using collected Bluetooth traces and analyze specifications of the collected data in terms of precision and results, to predict attendees behaviour and crowd movement. The data was collected on July 24th, 2010 by ten agents scanning for visible Bluetooth devices. The methodology for tracing Paléo festival attendees is a Bayesian approach derived by Danalet et al. [2012].

Representations of the pedestrian as a sole and healthy individual do not correspond to the reality and diversity of walking practices. The majority of urban pedestrians has to deal with constraints to their degrees of freedom in walking. We propose a typology of constraints, define and describe the “augmented pedestrian” and his “multi-task walk”. A qualitative study undertaken in Swiss urban districts aims to understand pedestrians in the complexity of their daily lives. The responsibilities assumed by individuals and the social ties that guide and structure their activities influence their walking experience. These elements have multiple visible or invisible repercussions which are expressed in terms of the physical and mental load and the corresponding increased need for energy and attention, limiting the degrees of pedestrians spatial and temporal freedom. Examples are: things to carry, tools to use, care responsibilities and activities, temporal pressure or emotional engagements. They may vary at each mobility activity or change during the mobility action. The pedestrian has to be understood as "augmented pedestrian”, performing a “multi-task walk” with several activities in parallel. The results show that the social reality of pedestrians has an influence on the spatial and temporal freedom of walking. Physical constraints go far beyond the limits already imposed by their own bodies. We identified three different types: 1. Individual long-term constraints 2. Individual constraints of short and middle term 3. External and inter-individual constraints More than half of the pedestrians observed in this study walked visibly with one and often with several physical and temporal constraints. More women were affected by external and inter-individual constraints, with more parallel tasks than men. Three times as many adult women as adult men had a physical commitment beyond walking. Three times as many female pedestrians as male pedestrians accompanied someone. The study showed that pedestrians needs and expectations of urban infrastructure - and its use - vary greatly. For example, persons with individual constraints of long-term seem to avoid crowded footpaths and those with high-speed walkers. Any increase in the numbers of pedestrians may lead to a subtle exclusion of this user group.

Pedestrian 3D Bounding Box Prediction

Alexandre Massoud Alahi, Yi Zhou Ju, Saeed Saadatnejad

Safety is still the main issue of autonomous driving, and in order to be globally deployed, they need to predict pedestrians' motions sufficiently in advance. While there is a lot of research on coarse-grained (human center prediction) and fine-grained predictions (human body keypoints prediction), we focus on 3D bounding boxes, which are reasonable estimates of humans without modeling complex motion details for autonomous vehicles. This gives the flexibility to predict in longer horizons in real-world settings. We suggest this new problem and present a simple yet effective model for pedestrians' 3D bounding box prediction. This method follows an encoder-decoder architecture based on recurrent neural networks, and our experiments show its effectiveness in both the synthetic (JTA) and real-world (NuScenes) datasets. The learned representation has useful information to enhance the performance of other tasks, such as action anticipation.
