Vertical Product Differentiation, Entry-Deterrence Strategies, and Entry Qualities, September 2005

We analyze the entry of a new product into a vertically differentiated market in which an entrant and an incumbent compete in prices. Here the entry-deterrence strategies of the incumbent firm rely on “limit qualities.” With a sequential choice of quality, a quality-dependent marginal production cost, and a fixed entry cost, we relate the entry-quality decision and the entry-deterrence strategies to the level of entry cost and the degree of consumer heterogeneity. Quality-dependent marginal production costs in the model entail the possibility of inferior-quality entry as well as an incumbent’s aggressive entry-deterrence strategies of increasing its quality level toward potential entry. Welfare evaluation confirms that social welfare is not necessarily improved when entry is encouraged rather than deterred.

Interstate Highway Map Indicating Vertical Clearance, May 15, 2011

The State of Iowa [STATE] and the Iowa Department of Transportation [IDOT] hereby is claim any warranty of any kind, express or implied, in reference to the information contained herein. The STATE and the IDOT neither assume nor authorize any person to assume for the STATE or the IDOT any liability in connection with the information contained herein, and there are no oral agreements or warranties regarding the information contained herein. Each and every person is hereby notified that the vertical clearances specified herein are subject to change due to resurfacing, surface buckling, weather conditions, or any other event. It is the responsibility of each and every vehicle operator to ascertain whether sufficient ACTUAL vertical clearance exists to move his vehicle or motor vehicle between the roadway and the underpasses and bridges listed herein. The May 15 date on this map reflects the end of the update schedule for the previous calendar year. Any vertical clearance restrictions which could or may change AFTER this date will not be reflected on this map. For the latest information on vertical clearance restrictions call the Office of Motor Carrier Services in Ankeny, (515) 237-3264 or visit http://www.iowadot.gov/mvd/omcs.

Recruiting and Retaining Women and Minorities in Public Sector Engineering Positions, HR-348, 1995

The objective of phase one of this research was to assess the degree to which currently employed Iowa Department of Transportation (DOT) employees would be affected by a more aggressive policy to recruit and retain women and minority engineers. The DOT's "Future Agenda" was used as a baseline to focus on efforts to update and implement a recruitment plan that would target underrepresented classes. The primary question that emerged out of phase one was how could the Iowa DOT strengthen its ties with Iowa State University (ISU) to produce increased numbers of in-state applicants for engineering positions. This introduced the objective of phase two, which was to identify problem areas resulting in unacceptably high attrition rates for women, minorities, and to a lesser degree, Caucasian men in the College of Engineering at ISU, particularly Civil and Construction Engineering (CCE). Past research has focused on (1) projected shortages of qualified civil engineers, (2) the obstacles confronting women in a traditionally male-oriented profession, and (3) minorities who are often unprepared to succeed in the rigors of an engineering curriculum because of a lack of academic preparedness. The researchers in this study, in contrast, chose to emphasize institutional reasons why women, minorities, and some Caucasian men often feel a sense of isolation in the engineering program. It was found that one of the key obstacles to student retention is the lack of visibility of the civil engineering profession. The visibility problem led to the hypothesis that many engineering students do not have a clear conception of what the practice of civil engineering entails. It was found that this may be a better predictor of attrition than the stereotypical assumption that a majority of students leave their engineering programs because they are not academically able to compete. Recommendations are offered to strengthen the ties between ISU's Department of CCE and the Iowa DOT in order to counter the visibility issue. It was concluded that this is a vital step because over the next 5-15 years 40% of DOT engineers currently employed will be phasing into retirement. If the DOT expects to draw sufficient numbers of engineers from within the state of Iowa and if increasing numbers of them are to be women and minorities, a university connection will help to produce the qualified applicants to fulfill this need.

Vertical Delineation, 2014

Vertical delineators are intended to warn drivers of an approaching curve while providing them with a better appreciation of the sharpness of a curve. Drivers can then select an appropriate speed before entering the curve. Delineation can also provide continuous tracking information once drivers are within the curve to help position their vehicles within the travel lane while traversing the curve. The most common type of vertical delineation is post mounted delineators (PMDs). These devices are usually flexible or rigid posts with some amount of reflective surface mounted along the roadside to provide additional delineation. Another treatment that has been used is to provide additional delineation on chevron posts.

Vertical Clearance Restrictions on Primary Roads and Primary Road Extensions: Standard U.S. Measurements [Vertical Clearance Log], May 1, 2015

The Vertical Clearance Log is prepared for the purpose of providing vertical clearance restrictions by route on the primary road system. This report is used by the Iowa Department of Transportation’s Motor Carrier Services to route oversize vehicles around structures with vertical restrictions too low for the cargo height. The source of the data is the Geographic Information Management System (GIMS) that is managed by the Office of Research & Analytics in the Performance & Technology Division. The data is collected by inspection crews and through the use of LiDAR technology to reflect changes to structures on the primary road system. This log is produced annually.
