Evaluation Of Kentucky’S “Click It Or Ticket” 2008 Campaign, Kenneth R. Agent, Eric R. Green, Ronald E. Langley

Kentucky Transportation Center Research Report

The objective of this report was to document the results of the “Click It or Ticket” 2008 campaign in Kentucky. The campaign involved a combination of earned media, paid media, and enforcement. The earned media started about three weeks prior to Memorial Day 2008 and continued through the enforcement period. The paid media campaign was for the two weeks prior to Memorial Day while the enforcement period was a two-week period including the week before and the week of Memorial Day.

The evaluation of the campaign included documenting the activities associated with the program (publicity and enforcement) and evaluating the …

Evaluation Of Median Barrier Safety Issues, Kenneth R. Agent, Jerry G. Pigman

Kentucky Transportation Center Research Report

The objective of this study was to evaluate the effectiveness of the Brifen TL-4 and Trinity CASS median cable barrier systems in preventing cross-median collisions on sections of I-64, I-71, and I-265 (Brifen system) and I-265 (Trinity system) in Jefferson County and on KY 4 (Brifen system) in Fayette County. An effort was made to identify crashes which involved a vehicle crossing a median. Using specific logic to identify this type of crash, 392 crashes were identified for the five-year period of 2001 through 2005. Using crash and mileage data resulted in an average of 0.28 crossover crashes per mile …

Evaluation Of Undrained Response From Drained Triaxial Shear Tests: Dem Simulations And Experiments, Sitharam T G, Jayan S. Vinod, Ravishankar B V

Faculty of Engineering - Papers (Archive)

The undrained shear response of monotonically loaded isotropically consolidated saturated sands can be characterised by a change in the excess pore pressure generation in the sample. The generation of positive and negative excess pore water pressures is related to contractive and dilative responses. The increase or decrease in pore water pressure continues until it reaches critical state (known as steady state for undrained tests). In general, Casagrande’s definition of critical state for sands has been utilised in most commonly used liquefaction analyses, and is referred to as the steadystate procedure (Castro, 1969; Casagrande, 1977; Castro & Poulos, 1977; Poulos et …

Evaluation Of Smear Zone Extent Surrounding Mandrel Driven Vertical Drains Using The Cavity Expansion Theory, Iyathurai Sathananthan, Buddhima Indraratna, Cholachat Rujikiatkamjorn

Faculty of Engineering - Papers (Archive)

In this study, an attempt is made to analyse the extent of the smear zone caused by mandrel driven vertical drains, employing the cavity expansion theory for soft clay obeying the modified Cam-clay model. The predictions are verified by large-scale laboratory tests, where the extent of the smear zone was estimated based on the indications such as the pore pressure generated during mandrel driving, change in lateral permeability and the water content reduction. This study reveals that the radius of smear zone is about 4-6 times the equivalent vertical drain radius, and the lateral permeability (inside the smear zone) is …
