The Effects Of Physical Activity On Greenhouse Gas Emissions For Common Transport Modes In European Countries, Aidan Duffy, Robert Crawford

Articles

This paper applies a life cycle methodology to estimate activity-related contributions of transport modes to GHG emissions. The methodology uses national input-output tables, environmental accounts, household budget data and nutritional data to derive food-sector GHG coefficients of consumption for ten European countries. The food energy requirements for each mode of transport are estimated taking account of the modal activity level and energy requirements. Walking, cycling, driving and bus travel are considered. Typical national food energy-related emissions for walking, cycling, and driving ranged from 25.6 - 77.3 gCO2-eq/pass.km, 10.4 - 31.4 gCO2-eq/pass.km and 1.7 - 5.2 gCO2-eq/pass.km; passenger transport was found …

Civil and Environmental Engineering

Shear-wave velocity (Vs) offers a means to determine the seismic resistance of soil to liquefaction by a fundamental soil property. This paper presents the results of an 11-year international project to gather new Vssite data and develop probabilistic correlations for seismic soil liquefaction occurrence. Toward that objective, shear-wave velocity test sites were identified, and measurements made for 301 new liquefaction field case histories in China, Japan, Taiwan, Greece, and the United States over a decade. The majority of these new case histories reoccupy those previously investigated by penetration testing. These new data are combined with previously published case histories to …

Design And Construction Cost Of A Water Line Underneath I-75 In Bowling Green, Ohio, V. Goduto, Alan Atalah

Construction Management Faculty Publications

The City of Bowling Green, OH operates a water distribution system that delivers high quality water. The system operates optimally in a grid system; larger, “trunk water mains,” are installed in a grid pattern on the outer limits of the system with smaller lines branching from the larger lines. Almost all the residential, industrial, and commercial areas in Bowling Green were originally limited to the west side of I-75. However over the past few decades, these areas grew on the east side of I-75. Two 24” water mains crossed underneath I-75 at the central and south part of the city …

Stewart, Kazushi Tohyama, Dimitios Zekkos

Civil and Environmental Engineering

The 2011 M_W = 9.0 Tohoku-oki earthquake generated a large number of unique soil liquefaction case histories, including cases with strong ground motion recordings on liquefiable or potentially liquefiable soils. We have compiled a list of 22 strong motion stations (SMS) where surface evidence of liquefaction was observed and 16 SMS underlain by geologically recent sediments or fills where surface evidence of liquefaction was not observed. Pre-earthquake standard penetration test data and borehole shear wave velocity (V_s) profiles are available for some stations, but critical information, such as grain size distribution and fines plasticity, are often …

In a standard test of reasoning, you are given a candle, a box of thumbtacks, and a book of matches. Your task is to attach the candle to the wall so that it does not drip onto the table below.

I thought about how to melt the wax and use it to stick the candle to the wall. What would you do?

This challenge is designed to reveal functional fixedness, mental blocks against using objects in a new way. The experience that comes with age is a disadvantage here because it leads to thinking of the normal use of the …

Tracking Trucks To Improve Performance, Mecit Cetin, Christopher M. Monsere

TREC Project Briefs

Freight transportation is an important part of Oregon’s economy, and the Oregon Department of Transportation, or ODOT, continually observes the highway system to make sure it is running as smoothly as possible. By monitoring the progress of individual trucks, ODOT can obtain performance metrics such as travel time, travel delays, and origin-destination flows. This information can help identify slow passages or bottlenecks in the highway system. Typical ways of obtaining these metrics, however, may involve purchasing expensive equipment, and may also raise privacy concerns if each truck is required to carry a tracking unit. To avoid these difficulties, Portland State …

Effective Criteria For Seismic Rehabilitation Planning Of Road Transportation Infrastructures, Mohammadreza Yadollahi, Rosli Mohamad Zin, Sadegh Asgari

Civil Engineering Faculty Publications

While seismic rehabilitation process for road infrastructures has been traditionally based on seismic factors, consideration of non-seismic factors is necessary for reliable project ranking. Non-seismic factors include socioeconomic criteria, determining the value of a project to its users’ community. Based on the information obtained from a questionnaire survey and literature review, this paper identifies a set of effective rehabilitation criteria (ERC) for seismic rehabilitation decision-making to develop a priority index that is applied to determine the rehabilitation priority. The identified RC will then be weighted for four types of road structures including bridges, tunnels, retaining walls, and buildings. The results …

Protecting Bridges From Earthquake Damage, Peter Dusicka

TREC Project Briefs

Earthquake damage to bridges can have serious effects on a transportation network. When a bridge is out, the damage can go well beyond what is immediately visible: in addition to the cost of repairing it, the state must deal with short-term and long-term interruptions to traffic. These interruptions can delay repair and construction, as well as impacting post earthquake emergency response and causing the loss of valuable time for commuters and freight. To prevent this situation, older bridges (ones that are past an average construction life of about 50 years) should be retrofitted with stronger materials, especially in earthquake- prone …
