The objective of this study was to identify measures appropriate to estimate travel time reliability and apply them to study the reliability of travel time under varying freeway operating conditions. More specifically, a case study was undertaken to study travel time reliability along the I-65 corridor in the State of Alabama. The objectives of this study were to: a) Calculate reliability metri...

To achieve autonomous indoor mobile robot navigation, the robot needs to identify the direction, obstacle position and other information. This paper describes a solution for indoor mobile robot navigation and obstacle distance detection which based on monocular vision. We use Hough transform to find the straight lines in the corridor environment which were used to find the vanishing point as th...

In this paper we present a new approach to robust 3D rigid body motion estimation and scene structure recovery using an epipolar corridor. In comparison to traditional two stage approaches we do not rely on independent establishment of feature point correspondences and subsequent computation of 3D motion parameters, but iteratively feed the motion parameters back to the point correspondence est...

A driver-yielding enforcement program that included decoy pedestrians, feedback flyers, written and verbal warnings, and saturation enforcement for a 2-week period was evaluated in the city of Miami Beach using a multiple baseline design. During baseline, data were collected at crosswalks along two major corridors. Treatment was introduced first at selected crosswalks without traffic signals al...

In this paper it is shown that simple, low-level motion cues, inspired by the visual navigation of flying insects, can be used to provide a mobile robot with the ability to traverse various corridor environments. Distances to the walls of the corridor and to potential obstacles are measured using the apparent angular velocity of patches in the image and the known motion of the robot.

Mean sets and footprints – p. 1/1

Background Investigation of local foot loading using baropodometry is highly relevant in both research and clinical settings. In order to reliably associate local pressure data with foot function and structure, anatomy-based masking of footprints is recommended, especially when foot anatomy or footprints are significantly altered. Previous studies combining baropodometry with stereophotogrammet...

The recognition of human behaviour from sensor observations is an important area of research in smart homes and ambient intelligence. In this paper, we introduce the idea of spatio-temporal footprints, which are local patterns in space and time that should be similar across repeated occurrences of the same behaviour. We discuss the spatial and temporal mapping requirements of these footprints, ...

As one of the leading method of electric wheelchairs, platoon driving using Adaptive Cruise Control (ACC) has been proposed to keep constant time-headway. The platoon driving system has been widely used assuming straight roads that has good visibility, but has not been used in narrow corridor. While, the gross weight of wheelchair changes drastically depending on passenger’s weight. In this pap...

this paper gives an account of the implementation of geomorphological, hydrogeological, hydrochemical and isotopic techniques to understand groundwater-surface water interactions in a multiple use area, los padres-la brava corridor (se of buenos aires province, argentina). the isophreatic map reveals a regional flow from the sw to ne sector, and allowed us to define the effluent-influent behav...
