    With 2000 to 2007 crash data, this study investigated the factors that contributed to injuries in collisions that involved at least one bus in the province of Alberta, Canada. Crashes of all types of buses (e.g., school, transit, intercity) were considered. Four logistic regression models were calibrated: single-vehicle collisions on highways, single-vehicle collisions on nonhighway locations, two-vehicle collisions on highways, and two-vehicle collisions on nonhighway locations. The analysis showed that weather conditions were a significant contributing factor in all four types of collisions, although crashes in adverse weather conditions resulted in fewer injuries. The type of collision, characteristics of collision partner, driver age of collision partner, and weather conditions had a significant effect on the level of severity of collisions on both highway and nonhighway locations. Other factors were shown to affect injury risk only in one particular situation. For instance, for highway-related collisions, the age of the collision partner had a significant effect on levels of accident severity, whereas the age of the bus driver did not. In addition, for highway collisions, the severity was higher for head-on crashes, bus–bus crashes, bus–truck crashes, bus–motorcycle crashes, older buses, crashes on grade and in sags, and crashes during dark and sun glare, whereas accident probability decreased with larger outside shoulder width. For nonhighway locations, crashes occurring near tunnels, overpasses, and signalized intersections were shown to result in a higher probability of injury. The results showed that single-bus collisions involving pedestrians at nonhighway locations had higher injury risk than collisions involving objects.

    Traction inverter has been the subject of many studies due to its essential role in the proper performance of the drive system. With the recent trend in increasing the input voltage in battery-powered electric vehicles, multilevel inverters have been proposed in the literature as a promising substitute for conventional two-level traction inverters. A critical aspect of utilizing multilevel structures is employing proper control and modulation techniques. The control system structure must be capable of handling a number of key issues, like capacitor voltage balancing and equal power loss sharing, which arise in multilevel topologies. This paper presents a review of the present-day traction drive systems in the industry, control and modulation techniques for multilevel structures in the inverters, as well as the principal challenges that need to be addressed in the control stage of the multilevel traction inverter. A comparison has been made between different methods based on the most important criteria and requirements of the traction drive system. Finally, future trends in this application are presented and some suggestions have been made for the next generation of traction drives.

    Planned special events attract thousands of attendees from nearby cities or suburbia by car and transit. In most cases, the majority of attendees use personal automobiles, and a high parking demand results in a short time, with a consequent parking shortage. Parking guidance information systems can solve the problem by displaying information on parking lot availability to dynamically divert vehicles. This study focused on optimizing dynamic parking guidance information for automobile drivers at special events. An original multimode traffic network was converted to a novel network by considering parking lots as dummy links; therefore the shortest path and traffic assignment could be implemented in this extended network. A bilevel programming model based on quasi-dynamic route choice and linear programming was proposed to optimize the dynamic parking guidance information. On the basis of travelers' reaction to the guidance, stochastic dynamic user optimal route choice was employed within the lower-level model. The upper-level model was a linear program aimed at minimizing network total travel time. The solutions of the bilevel programming model were based on discrete particle swarm optimization and the method of successive average algorithms. Results of a case study implemented with a hypothetical network indicated that the optimization model could reduce the system total travel time by 4%.

    A land use and transportation interaction model was developed for the Sacramento, California, region, using the MEPLAN framework. The model represents land markets directly together with location-choice processes of different industry and household categories and the interactions among them. These resulting economic interactions lead to trip matrixes that are assigned to a multimodal, capacity-restrained transportation network, generating travel times and disutilities that influence the location-choice process in the period from 1990 to 2015. A range of different policy options is simulated for that period. Five different scenarios are compared with a trend scenario, three representing different long- and short-term government transportation supply scenarios, one representing incentives and disincentives to encourage land use patterns complementary to an improved transit system, and one combining the land-incentive scenario with higher prices for private vehicle use. The scenario predictions differ in mode choice, firm location, residential location, development patterns, vehicle kilometers traveled, and land rents. Various land uses are seen to be bidding against each other, and the differences in spatial arrangements between scenarios are quite complex and demonstrate the richness of the model. Certain changes take time to develop, demonstrating the need for a long-term approach to planning.

    Solvent deasphalting and visbreaking are two important technologies in the development of processes for partial upgrading of oilsands-derived bitumen to improve oil fluidity for pipeline transport. This work investigated the impact of the process sequence, solvent deasphalting followed by visbreaking (SDA-Vis) compared to visbreaking followed by solvent deasphalting (Vis-SDA). Thermal conversion during visbreaking was performed at 380 °C for 85 min, and solvent deasphalting was performed with n-pentane. Using this combination of processes in either sequence changed bitumen from a viscosity-limited fluid to a density-limited fluid with respect to pipeline specifications. The density and viscosity of the oil products from SDA-Vis and Vis-SDA were comparable. It was found that SDA-Vis achieved 2 wt % higher liquid yield than Vis-SDA. Conversely, Vis-SDA produced an oil product with higher hydrogen to carbon ratio compared to SDA-Vis. This difference could be explained in terms of hydrogen transfer during the...

    Abstract In this study, a regional life-cycle assessment (LCA) framework is developed to assess compressed natural gas (CNG) and liquefied natural gas (LNG) as fuel alternatives to diesel for a transit bus in Victoria, British Columbia, Canada. The driving pattern and road gradient of a public transit bus route are considered in both directions to capture real-world driving behavior. The real-time fuel consumption and emissions of the transit bus configurations are calculated by dynamic vehicle simulation using Simcenter Amesim software. By considering the effect of road gradient, a 12% difference in computed fuel consumption is shown for bus travel in the two opposing directions of the bus line. The results also reveal that the majority of life cycle greenhouse gas (GHG) emissions are associated with on-board emissions. Overall, switching from diesel to CNG or LNG reduces GHG emissions by 4.8% and 8.1%, respectively.

    Infrastructure networks such as highways and pipelines have recently been at the center of attention for contractors and owner organizations. Due to their large size and their repetitive/distributed nature, construction and/or maintenance operations for such networks become complex tasks that require huge resources, particularly manpower. In order to provide a transparent tool for quick manpower planning and sensitivity analysis, a graphical approach (using nomographs) is introduced in this paper. The nomographs encode the mathematical formulation, and the results of many optimization experiments, of a distributed model for scheduling large projects with multiple sites. Accordingly, the nomographs can be readily utilized by practitioners to estimate the manpower needed to meet a predefined deadline, under anticipated network-level risks due to unfavorable site conditions. Details on the development of the nomographs are presented in the paper along with an example to demonstrate their usefulness for supporting manpower planning decisions and for what-if analysis. The nomographs also present researchers with a simple yet powerful approach to make research results readily usable by practitioners.

    Consacré à la question de la traduction en matière de mathématiques, qu’il aborde ici par l’intermédiaire d’un acteur particulier, l’« élève », à la fois destinataire et, parfois, producteur de traductions, le présent article se structure principalement autour de trois études de cas. La première concerne la production, dans les États-Unis des années 1820 et 1830, d’une série de manuels de mathématiques et de mécanique théorique, élaborés à partir de manuels français et destinés aux étudiants de l’Université Harvard et de l’Académie militaire de West Point. La seconde s’attache à la traduction, en 1828, d’un manuel anglais dans l’espace germanophone. La troisième se penche sur la presse mathématique française de la première moitié du xixe siècle, illustrée ici par le journal des candidats à l’École polytechnique et à l’École normale (Nouvelles annales de mathématiques) et le journal des « progrès en mathématiques » (Journal de mathématiques pures et appliquées). Les objectifs poursuivis consistent à faire émerger des points saillants, à identifier des pistes prometteuses pour la suite de l’enquête, et à tenter d’établir un premier bilan, provisoire et sujet à des modifications, sur la question de la traduction mathématique et de ses éventuelles spécificités par rapport aux traductions relevant d’autres domaines. This article, based on three case studies, deals with the “translation” issue in the field of mathematics, here addressed through the specific figure of the “student,” simultaneously recipient, but sometimes also author, of translations. The first case study concerns American adaptations of a series of French mathematics and mechanics textbooks geared towards students at Harvard and at West Point Military Academy in the 1820s and 1830s. The second considers the 1828 translation of an English textbook in a German-speaking environment. The third focuses on two 19th century French mathematics journals that regularly published translations: the first was intended for École polytechnique or École normale candidates (Nouvelles annales de mathématiques) while the second was concerned with “the progress in mathematics” (Journal de mathématiques pures et appliquées). The article seeks to pinpoint highlights, identify promising investigative pathways and, finally, attempt to offer an initial and temporary assessment, subject to modification, of the question of mathematics translation and its possible specificities in relation to translations in other fields.

    With 2000 to 2007 crash data, this study investigated the factors that contributed to injuries in collisions that involved at least one bus in the province of Alberta, Canada. Crashes of all types of buses (e.g., school, transit, intercity) were considered. Four logistic regression models were calibrated: single-vehicle collisions on highways, single-vehicle collisions on nonhighway locations, two-vehicle collisions on highways, and two-vehicle collisions on nonhighway locations. The analysis showed that weather conditions were a significant contributing factor in all four types of collisions, although crashes in adverse weather conditions resulted in fewer injuries. The type of collision, characteristics of collision partner, driver age of collision partner, and weather conditions had a significant effect on the level of severity of collisions on both highway and nonhighway locations. Other factors were shown to affect injury risk only in one particular situation. For instance, for highway-related collisions, the age of the collision partner had a significant effect on levels of accident severity, whereas the age of the bus driver did not. In addition, for highway collisions, the severity was higher for head-on crashes, bus–bus crashes, bus–truck crashes, bus–motorcycle crashes, older buses, crashes on grade and in sags, and crashes during dark and sun glare, whereas accident probability decreased with larger outside shoulder width. For nonhighway locations, crashes occurring near tunnels, overpasses, and signalized intersections were shown to result in a higher probability of injury. The results showed that single-bus collisions involving pedestrians at nonhighway locations had higher injury risk than collisions involving objects.

    Traction inverter has been the subject of many studies due to its essential role in the proper performance of the drive system. With the recent trend in increasing the input voltage in battery-powered electric vehicles, multilevel inverters have been proposed in the literature as a promising substitute for conventional two-level traction inverters. A critical aspect of utilizing multilevel structures is employing proper control and modulation techniques. The control system structure must be capable of handling a number of key issues, like capacitor voltage balancing and equal power loss sharing, which arise in multilevel topologies. This paper presents a review of the present-day traction drive systems in the industry, control and modulation techniques for multilevel structures in the inverters, as well as the principal challenges that need to be addressed in the control stage of the multilevel traction inverter. A comparison has been made between different methods based on the most important criteria and requirements of the traction drive system. Finally, future trends in this application are presented and some suggestions have been made for the next generation of traction drives.

    Planned special events attract thousands of attendees from nearby cities or suburbia by car and transit. In most cases, the majority of attendees use personal automobiles, and a high parking demand results in a short time, with a consequent parking shortage. Parking guidance information systems can solve the problem by displaying information on parking lot availability to dynamically divert vehicles. This study focused on optimizing dynamic parking guidance information for automobile drivers at special events. An original multimode traffic network was converted to a novel network by considering parking lots as dummy links; therefore the shortest path and traffic assignment could be implemented in this extended network. A bilevel programming model based on quasi-dynamic route choice and linear programming was proposed to optimize the dynamic parking guidance information. On the basis of travelers' reaction to the guidance, stochastic dynamic user optimal route choice was employed within the lower-level model. The upper-level model was a linear program aimed at minimizing network total travel time. The solutions of the bilevel programming model were based on discrete particle swarm optimization and the method of successive average algorithms. Results of a case study implemented with a hypothetical network indicated that the optimization model could reduce the system total travel time by 4%.
