The effect of organismic variable age on human cognitive performance was studied under the impact of vibration in different automobile driving environments, namely city streets, rural roads and highways. Reaction time was measured in milliseconds through a human response measurement system specifically designed for the purpose. Results of the study showed that age had a significant effect in ci...

Humans' remarkable capacity on rapid natural scene categorization has been widely studied in neuroscience. Recently, a functional MRI (fMRI) study showed that in human brain, decoding of natural scenes from line drawings was very similar to those from color photographs. In this paper, based on recently proposed computational cognition model of Perception, Memory and Judgement (PMJ model), work ...

This article explores whether the use of LiDAR data in detecting transport network obstructions shortens the time required to reach disaster sites. It presents a method for doing this using LiDAR data collected in New Orleans, Louisiana (USA) before and after Hurricane Katrina. It involves identifying all the LiDAR data points that lie within transport links (e.g., highways or streets) and perf...

Operational speed is an index that represents drivers’ speeding behaviors and shows the comfort and safety levels they experience. Many models had been proposed to predict operational speed in tangent and curve segments of highways. Most of these works had used geometric, with few of them conducted using roadside variables to predict operational speed. Also, the operational speed study in multi...

In this paper, we present a real-time algorithm for local simultaneous localization and mapping (SLAM) with detection and tracking of moving objects (DATMO) in dynamic outdoor environments from a moving vehicle equipped with a laser scanner and two radars. To correct vehicle location from odometry we introduce a new fast implementation of incremental scan matching method that can work reliably ...

The large number of rear end collisions due to driver inattention has been identified as a major automotive safety issue. In this paper, we describe a 3-phase vehicle tracking methodology with a single moving camera mounted on the driver’s automobile as input for use in detecting rear vehicles on highways and city streets. In the first phase, vehicle detection, a rear vehicle is detected by sym...

Autonomous road following is a domain which spans a range of complexity from p r l y defmed, unmarked dirt roads to well defined, well marked, highly structured highways. The YARF system (for Yet Another Road Follower) is designed to operate in the middle of this range of complexity, driving on laban streets. Our research program has focused on the use of featureand situation-specific segmentat...

This paper pertains to the reduction of measurement errors due to drift in rate gyros used for tracking the position of moving vehicles. In these applications, gyros and odometry are often used to augment GPS when GPS reception is unavailable. Drift in gyros causes the unbounded growth of errors in the estimation of heading, rendering low-cost gyros almost entirely useless in applications that ...
