Purpose This paper aims to present a summary of the performance measurement and evaluation plan of the Wyoming connected vehicle (CV) Pilot Deployment Program (WYDOT Pilot). Design/methodology/approach This paper identified 21 specific performance measures as well as approaches to measure the benefits of the WYDOT Pilot. An overview of the expected challenges that might introduce confounding factors to the evaluation effort was outlined in the performance management plan to guide the collection of system performance data. Findings This paper presented the data collection approaches and analytical methods that have been established for the real-life deployment of the WYDOT CV applications. Five methodologies for assessing 21 specific performance measures contained within eight performance categories for the operational and safety-related aspects. Analyses were conducted on data collected during the baseline period, and pre-deployment conditions were established for 1 performance measures. Additionally, microsimulation modeling was recommended to aid in evaluating the mobility and safety benefits of the WYDOT CV system, particularly when evaluating system performance under various CV penetration rates and/or CV strategies. Practical implications The proposed performance evaluation framework can guide other researchers and practitioners identifying the best performance measures and evaluation methodologies when conducting similar research activities. Originality/value To the best of the authors’ knowledge, this is the first research that develops performance measures and evaluation plan for low-volume rural freeway CV system under adverse weather conditions. This paper raised some early insights into how CV technology might achieve the goal of improving safety and mobility and has the potential to guide similar research activities conducted by other agencies.

Transportation engineering curricula at the undergraduate and graduate levels are critical to the development of technical competency in future transportation engineering professionals—those who will be responsible for the planning, design, construction, operation, and maintenance of safe and efficient transportation systems. This paper provides an analytic review of journal articles and refereed conference papers addressing how transportation engineering curricula have changed over time. The literature review found 51 articles for analysis, with an increased frequency of those publications over time. Curriculum issues described in these papers include how transportation fits broadly within engineering programs and, more specifically, within civil engineering programs, which topics are addressed in transportation courses, and how these courses attend to stakeholder needs. This analytic review of the literature provides a resource for transportation engineering educators, administrators, and resear...

Background: In the Australian QASC Trial (Lancet 2013), better glucose and fever control improved 90 day outcomes when nurses adhered to strict monitoring/treatment protocols. We examined variance from guideline specific care for glucose and fever in an American sample. Methods: An observational study was conducted to assess compliance with AHA/ASA stroke guidelines for glucose and fever control in consecutive acute stroke patients from 5 different U.S. Stroke Centers. The first 5-days of glucose/temperature data were analyzed along with demographics and outcome measures. Results: A total of 1669 consecutive glucose and 3782 consecutive temperature measurements were taken from a sample of 235 acute stroke patients; the sample was 87% ischemic and 13% ICH, with admission median NIHSS 4.0 (range 0-34) and ICH score median 1 (range 0-5). 26% of ischemic strokes received IVtPA and/or thrombectomy. HbA1c was 5.7 + .65 (median range 4.8-11.2) in non-DM diagnosed patients vs. 8.3 + 2.3 (range 5.0-14.1; 95%CI=1.9-3.1; p180 mg/dL for >4 hours in 33% during hospitalization (Table), and the most frequent method (35%) for glucose control was regular insulin sliding scale. Temperature was >37.5 o (noncompliant with European/Australian [E/A] standards) for >4 hours in 27% of patients, and >38 o (noncompliant with US standards) for >4 hours in 10% of patients; 8% were out-of-control >8 hours (range 9-96, median 16.5 hours out-of-control) and 39% did not have temperature measured in the ED. mRS and LOS were significantly worse if temperature exceeded the E/A and US standards (Table). Temperature control to o C was an independent predictor (p Conclusions: Our study underscores the need for more vigilant control of glucose and temperature by nurses at U.S. hospitals. Given the time-sensitive ability of brain to recover from ischemia, even short-term non-compliance may have detrimental effects.

Public involvement in transportation improvement programming is becoming increasingly important as well as being a recommendation of federal legislation in the United States. Although most transportation planning agencies have not actively involved the public during this stage of the planning process, there are many benefits to doing so, such as, gaining support from the public for the funded project list, increasing the credibility of agencies, reducing project costs, and avoiding construction delays. Effective public involvement during the programming step incorporates inclusive participation, two-way communications, transparent processes, and serious treatment of the public’s input. This paper presents a model for public involvement in the programming process with all these features using a web-based portal application with a Public Participation Geographic Information System (PPGIS). The process is composed of the following five steps: describing values and concerns, determining criteria, reviewing projects, evaluating scenarios, and creating reports. Challenges agencies may encounter in implementing such a system are also covered in this paper.

The development and widespread implementation of best practices in transportation engineering classrooms is important in attracting and retaining the next generation of transportation engineers. Engineering education professionals have uncovered many best practices in the field; however, the process of effectively disseminating and ultimately achieving the widespread adoption of these best practices by others is not yet well understood. Sixty participants, including faculty members, Ph.D. students, and public-sector employees, attended a transportation engineering education workshop convened in Seattle to promote the collaborative development and adoption of active learning and conceptual exercises in the introduction to transportation engineering class. Participant assessments were conducted in the form of presurvey, postsurvey, and follow-up survey. Results showed immediately positive shifts in participant beliefs about the importance of active learning and conceptual exercises, with declines du...
