INFLUENCE OF DOMAIN SHIFT FACTORS ON DEEP SEGMENTATION OF THE DRIVABLE PATH OF AN AUTONOMOUS VEHICLE
LiDAR Computer Vision Self-driving cars Weakly-supervised learning Convolutional Neural Network Domain adaptation
2018/6/4
One of the biggest challenges for an autonomous vehicle (and hence the WEpod) is to see the world as humans would see it. This understanding is the base for a successful and reliable future of autonom...
Self-calibration system for the orientation of a vehicle camera
Camera Calibration Orientation Orthorectification Infrastructure
2015/8/24
The process of calibration is a prerequisite for each computer vision system. Calibration involves calculating both intrinsic and extrinsic parameters of the camera. While intrinsic parameters (focal ...
GOOD SAMPLE CONSENSUS ESTIMATION OF 2D-HOMOGRAPHIES FOR VEHICLE MOVEMENT DETECTION FROM THERMAL VIDEOS
Infrared surveillance Machine vision Object recognition
2015/5/18
In this contribution we describe a method to assess the activity of vehicles based on airborne image sequences taken by an infrared
camera. Active vehicles often appear as a configuration of a dark a...

electric vehicle sales unique chicken egg problem
2015/3/4
In 2011, an important national priority was declared: Put 1 million electric vehicles on the road by 2015. Since then, sales of plug-in electric vehicles have risen and continue to rise, but they pale...
The Effect of External Distractions on Novice and Experienced Drivers' Anticipation of Hazards and Vehicle Control
External Distractions on Novice Experienced Drivers Hazards and Vehicle Control
2014/10/22
Out-of-vehicle distractions were identified as contributing factors to about 29.4 % of all crashes that were reported between the years 1995 to 1999 (Stutts J. K., 2005; Stutts J. R., 2001). These cra...

2014/10/22
State Departments of Transportation (DOTs) today are seeking financing alternatives so that transportation infrastructure investments can become less dependent on the amount of fuel U.S. drivers consu...
Modeling the land-use correlates of vehicle-trip lengths for assessing the transportation impacts of land developments
Trip-lengths impacts-assessment regression model
2013/11/21
This study developed models that relate trip lengths to the land-use characteristics at the trip ends (both production and attraction ends). Separate models were developed by trip purpose. The results...
Measuring the impacts of local land-use policies on vehicle miles of travel: The case of the first big-box store in Davis, California
travel behavior vehicle-miles traveled retail travel
2013/11/21
Concerns over climate change have brought new impetus to the goal of reducing vehicle travel through land-use policy. To determine the degree to which land-use policies are effective in reducing vehic...
