Measurement of recurring versus non-recurring congestion : technical report by Mark E Hallenbeck( Book )

6 editions published in 2003 in English and held by 32 WorldCat member libraries worldwide

A research effort was initiated to develop and test a methodology to estimate the extent to which urban congestion is produced by the routine presence of large numbers of vehicles on a facility (so-called recurring congestion) versus unexpected disruptions or other events (non-recurring congestion), particularly lane blocking incidents. An analysis was performed using a preliminary methodology to estimate the magnitude, extent, and relative causes of congestion on urban freeways in the central Puget Sound region of Washington State. This information is designed to assist transportation agencies in 1) selecting the most appropriate strategies to improve freeway operations, and 2) allocating available resources to achieve those improvements. This paper documents the preliminary methodology and results from this ongoing research project

Anchorage of large-diameter reinforcing bars grouted into ducts( Book )

3 editions published in 2008 in English and held by 17 WorldCat member libraries worldwide

The use of a few large-diameter reinforcing bars for the construction of precast concrete bridge bents allows simplified construction by reducing the number of alignments to be made in the field. These bars are grouted into ducts in a precast concrete cap beam. In the proposed precast concrete substructure system, the grouted bars carry tensile forces across the joint between the column and cap beam. This joint is the yielding element in the structural system, and it is crucial to the performance of the structure that the bars yield before other failure mechanisms, including bond failure, occur. However, the cap beam is typically insufficient to anchor the bar, as the depth of the beam is substantially less than the American Association of State Highway and Transportation Officials (AASHTO) bridge code allows. For this project, 17 pullout tests were conducted to determine the bond characteristics and development length of large-diameter bars grouted into ducts. The bars tested ranged in size from #8 to #18. Pullout tests conducted with embedment lengths of at least six bar diameters yielded the reinforcing bar, while the test conducted with an embedment length of 14 bar diameters resulted in bar fracture. The tests and subsequent analysis showed that the bond of these grouted connections is significantly better than the bond of bars cast directly into concrete. The development lengths needed to fully anchor the bar are therefore within the depth available in the cap beam

An evaluation of engineering treatments and pedestrian and motorist behavior on major arterials in Washington State by Katherine D Davis( Book )

2 editions published in 2008 in English and held by 15 WorldCat member libraries worldwide

This report examines pedestrian and motorist behavior on arterials in Washington State and determines how, if at all, these behaviors change when various engineering treatments are applied. The treatments that were examined included crosswalk markings, raised medians, in-pavement flashers, signage, stop bars, overhead lighting, and sidewalks. The relationships between pedestrian travel and transit use, origin-destination patterns, traffic signals, and schools were also explored. The study examined seven locations in the state of Washington. These were State Route (SR) 7 at South 180th Street in Spanaway, SR 99 at South 152nd Street in Shoreline, SR 99 at South 240th Street in Kent, SR 2 between South Lundstrom and King Streets in Airway Heights, SR 2 at Lacrosse Street in Spokane, SR 2 at Rowan Avenue in Spokane, and SR 2 at Wellesley Avenue in Spokane. Because pedestrian-vehicle collisions are rare when specific locations are studied, other criteria were used to evaluate the conditions and behaviors that were present. These included "conflicts" such as running behavior, motorists having to brake unexpectedly to avoid a pedestrian, pedestrians waiting in the center lane to cross, and more. These unreported, but very common, occurrences enabled the researchers to gain a better understanding of both pedestrian and motorist concerns and behaviors and the effects that improvements might have. The study concludes that the causes of conflicts are highly varied: ignorance of or noncompliance with the law (by the motorist or the pedestrian), inattention, vehicles following too closely, impatience, anxiety in attempting to catch a bus, use or non-use of pedestrian facilities, placement of features in the built environment, and more. While pedestrian/motorist interaction improves with improved visibility (something which can be obtained through better engineering design and the removal of visual clutter) better education and/or enforcement will also be needed to achieve significant safety benefits
