Crash effects of hard shoulder runnings in freeways
- 2018
-
Conference paper (peer-reviewed)abstract
- This paper presents the result of a research project carried out to investigate the safety effect of the hard shoulder running in freeway facilities. Traffic congestion is increasing in urban freeways and freeway operation authorities in many countries are applying a variety of traffic control devices to increase vehicle carrying capacity at peak times. The hard shoulder running is one of the efficient devices applied to deal with traffic congestion in freeways and it creates an extra lane, relatively cheaply, at fixed times where there are known bottlenecks. Despite the popular use in South Korean freeway facilities, the hard shoulder running became a research subject recently, because many crashes start to occur within its surrounding areas. Both the total crash number and the injury crash number in the hard shoulder running have significantly increased. Transportation engineers are wondering whether this crash increase is casual or correlated with the application of the hard shoulder running. If proved that the hard shoulder running carries undesirable results, its application in freeway facilities will be no longer justifiable.

When will smart antennas be ready for the market? : Part I
- 2005
-
In: IEEE signal processing magazine (Print). - 1053-5888 .- 1558-0792. ; 22:2, s. 87-92
-
Journal article (other academic/artistic)abstract
- This work aims to shed more light on the issue of why smart antennas haven't yet penetrated the market despite all the research efforts that have been put into the technology. The paper looks at this issue from various perspectives and subdivides the discussions into fixed or nomadic and high mobility applications because of the different types of markets, demands, and technological barriers.

When will smart antennas be ready for the market? : Part II - results
- 2005
-
In: IEEE signal processing magazine (Print). - 1053-5888 .- 1558-0792. ; 22:6, s. 174-176
-
Journal article (other academic/artistic)abstract
- The aim of this two-part forum is to shed more light on the future of smartantennas (SA) through discussions among a balanced group of experts from academia and industry. In part I, which appeared in the March 2005 issue of IEEE Signal Processing Magazine, each of the experts stated his own opinion after exchanging some thoughts by e-mail. Then, a panel session took place at ICAS-SP'05 and a public poll followed. Now, in part II, the results are summarized by the experts. The central topic of the forum was the expectedmarket breakthrough of SA.
