There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.

Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

I and i

According to W. Edwards Deming, American companies require nothing less than a transformation of management style and of governmental relations with industry. In Out of the Crisis, originally published in 1982, Deming offers a theory of management based on his famous 14 Points for Management. Management's failure to plan for the future, he claims, brings about loss of market, which brings about loss of jobs. Management must be judged not only by the quarterly dividend, but by innovative plans to stay in business, protect investment, ensure future dividends, and provide more jobs through improved product and service. In simple, direct language, he explains the principles of management transformation and how to apply them.

Traditional engineering instruction is deductive, beginning with theories and progressing to the applications of those theories Alternative teaching approaches are more inductive Topics are introduced by presenting specific observations, case studies or problems, and theories are taught or the students are helped to discover them only after the need to know them has been established This study reviews several of the most commonly used inductive teaching methods, including inquiry learning, problem-based learning, project-based learning, case-based teaching, discovery learning, and just-in-time teaching The paper defines each method, highlights commonalities and specific differences, and reviews research on the effectiveness of the methods While the strength of the evidence varies from one method to another, inductive methods are consistently found to be at least equal to, and in general more effective than, traditional deductive methods for achieving a broad range of learning outcomes

Different wireless communication technologies (i.e. Wi-Fi, WiMAX) have been used as alternatives or supplement to wired communication in Intelligent Transportation Systems (ITS). Widespread deployment of wireless technologies needs clear understanding of limitations and advantages in different conditions. In this research, several field tests were performed to evaluate the performance of Wi-Fi wireless technology in multiple field conditions with varying qualities of Wi-Fi properties. Field tests revealed that modulation rates, transmission power, line of sight, distance between devices play critical role in the performance of Wi-Fi connections between two adjacent nodes in different roadway conditions. To achieve a desired level of performance between adjacent nodes in a wireless traffic sensor network, minimum network performance must be realized in the field. Traffic agencies can identify the achievable performance, such as saturated throughput, delivery ratio and received signal strength of the communication link at a particular location, by following the field test procedures presented in this paper.

Evaluation of Wireless Communication Performance Between Adjacent Nodes for Intelligent Transportation Systems Applications

The Safe, Accountable, Flexible, and Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) was signed into effect on August 10, 2005 creating a positive agenda for increased safety on the nation’s highways. The legislation established a requirement that each state implement a new Highway Safety Improvement Program (HSIP) providing data-driven decision-making for safety improvement expenditures and support for evaluations of safety improvements with empirical results. In preparation for these requirements, the Federal Highway Administration developed a suite of new safety analysis tools to help State Departments of Transportation identify safety problems and potential countermeasures. Consequently, the tools have introduced a new set of requirements for safety data, such as detailed road design and comprehensive volume data. Unfortunately, many states currently lack the data elements and database linkages required by the new analysis tools. In response to the road design data needs, this research evaluated a low-cost method for determining horizontal road design data using an instrumented vehicle equipped with satellite differentially corrected GPS by OmniStar; thus, by-passing the need to conduct field surveys or manually extract data from historic design drawings. Two rural two-lane roadway segments were studied. Researchers tested methods to obtain and automatically extract design data and compare with design drawings. The analysis revealed that the automatically extracted data closely matched the data in the design drawings. In addition, researchers identified several issues associated with the acquisition and use of the design drawings for safety analysis, further supporting the need for efficient and effective data collection techniques.

Federal Regulation 23 CFR 511 promises to improve the traveler information that assists motorists to make better travel decisions. In accordance with this regulation, all state departments of transportation (DOTs) are required to provide real-time traveler information including construction activity, lane blocking incidents, adverse weather conditions, and travel times on certain facilities, by November 8, 2014. In this study, the researchers used an online survey to collect information from State DOTs and their associated representatives from the US Federal Highway Administration (FHWA). A survey was distributed electronically to FHWA representatives, State DOT Operations Engineers, and State DOT Intelligent Transportation Systems Coordinators who were active in the implementation in their agency’s real-time systems management information program. The survey results illustrated that, processing of field data into travel times is most frequently done with software from vendors, and the majority of the agencies currently meet the accuracy thresholds required by the new law. The findings also revealed some practices that require improvement, including methods for identifying inaccurate travel times and the use of statistics for data sampling purposes. Overall the findings of this study are relevant to both practitioners and researchers because they detail current reported practices of how DOTs are collecting, processing, and disseminating travel time data, and how DOTs are measuring the quality of the data.

State Efforts Towards the Real-Time Systems Management Information Program Requirements for Travel Time

Efficient training is an essential component of work force development for transportation agencies. The South Carolina Department of Transportation (DOT) recognized one such training need in its management of contracts for professional services consultants. This recognition led to a research effort to identify standardized procedures in the procurement and administration of these contracts, resulting in the development of a training manual and daylong pilot training session. Although the session received positive feedback, it limited the time and location for delivery. This traditional, in-class method is no longer the only available option. Asynchronous online training presents agencies with the option of providing training to employees regardless of their spatial or schedule variabilities while minimizing the need for instructor effort and availability. In light of this change, the South Carolina DOT commissioned a subsequent research effort to study best practices for development, delivery, and assessm...
