SIMPLE APPROACHES TO IMPROVE THE AUTOMATIC INVENTORY OF ZEBRA CROSSING FROM MLS DATA
Point clouds LiDAR Automatic Processing Traffic signs Road Inventory 3D Modelling
2015/9/21
The city management is increasingly supported by information technologies, leading to paradigms such as smart cities, where decision-makers, companies and citizens are continuously interconnected. 3D ...
3D zebra-crossing reconstruction from stereo rig images of a ground-based mobile mapping system
Zebra-crossing detection Pedestrain crossing Road-mark 3D Reconstruction
2015/8/24
Zebra-crossings are very specific road features that are less generalized when imaged at different scales. We aim to use zebra-crossings as control objects for georeferencing the images provided...
Researchers from Lehigh University, Japan and Canada have advanced a step closer to the dream of all-optical data transmission by building and demonstrating what they call the “world’s first fully fun...
IMPROVEMENT OF ROAD CROSSING EXTRACTION AND EXTERNAL EVALUATION OF THE EXTRACTION RESULTS
Road crossing modeling extraction correction evaluation
2015/3/25
The extraction of road crossings is often neglected by systems for automatic road extraction. Frequently, crossings arise as
by-products of the grouping step. This leads to geometrical inaccuracies a...
3D MODELLING: CROSSING TRADITIONAL BOUNDARIES BETWEEN DIFFERENT RESEARCH AREAS
Interdisciplinarity 3D modelling architecture GIS dialectic model common integrative approach
2015/3/3
A 3D reconstruction of complex architecture will never be complete nor constructively sound without the combination of knowledge and expertise from different scientific branches. Yet, how should all t...
Evaluating the Effectiveness of Wildlife Crossing Structures in Southern Vermont
Monitoring Multi-taxa Road Wildlife Crossing
2014/12/11
Roads are prominent, contiguous features covering approximately 1% of the United States land mass and have been built for decades with little consideration for ecological effects. Increasingly, the im...
Evaluating At-Grade Rail Crossing Safety along the Knowledge Corridor in Massachusett
At-Grade Rail Crossing Safety Knowledge Corridor Massachusett
2014/10/22
Highway-rail grade crossings are safer than ever, but collisions between motor vehicles and trains persist. Some collisions could be prevented by actively maintaining such grade crossings, yet many at...
Reliability analysis of pedestrian safety crossing in urban traffic environment
Pedestrian error Traffic accident Reliability Waiting duration
2012/4/12
This paper describes the pedestrian safety crossing behaviour at signalized crosswalks in an urban traffic environment based on human reliability analysis. In our research, pedestrians’ waiting durati...

Offline and Online Media Online Advertising TV Web Sites Online Portals
2009/12/2
This paper presents findings of a study comparing the advertising on the web sites supported by offline media and on the dot.com media that only have online presence. The study analyzes the advertisin...
Zero Crossing Counter for Accuracy Improvement of FMCW Range Detection
Zero Crossing Counter Accuracy Improvement FMCW Range Detection
2009/7/28
civil and military purposes FMCW radars are widely used. The theoretical background is well-established. Nevertheless, improvement of various aspects of these radars is still required. Signal processi...
Zero-Crossing Based Demodulation of Minimum Shift Keying
Minimum shift keying modulation receiver performance zero-crossing properties
2009/7/28
Minimum shift keying (MSK) modulation has features such as constant envelope, compact spectrum and good error performance, which are all desirable in many digital applications including mobile radio. ...
Wannier Basis Design and Optimization of a Photonic Crystal Waveguide Crossing
Design optimization photonic crystal (PC) devices
2015/8/11
We employ a novel platform for the realization of tunable photonic crystal (PC) circuits together with a Wannier basis modeling and optimization scheme in order to design a broad-band waveguide crossi...
