Abstract: We address the problem of predicting whether a driver facing the yellow-light-dilemma will cross the intersection with the red light. Based on driving simulator data, we propose a stochastic hybrid system model for driver behavior. Using this model combined with Gaussian process estimation and Monte Carlo simulations, we obtain an upper bound for the probability of crossing with the red light. This upper bound has a prescribed confidence level and can be calculated quickly on-line in a recursive fashion as more data become available. Calculating also a lower bound we can show that the upper bound is on average less than 3% higher than the true probability. Moreover, tests on driving simulator data show that 99% of the actual red light violations, are predicted to cross on red with probability greater than 0.95 while less than 5% of the compliant trajectories are predicted to have an equally high probability of crossing. Determining the probability of crossing with the red light will be important for the development of warning systems that prevent red light violations.
The heating and cooling requirements of K-12 schools, college and university educational, medical research and healthcare delivery campuses are a large market for boiler pressure vessel manufacturers, installers, maintenance personnel and inspectors. The demand for building new, and upgrading existing boilers — either single building boilers, regional boilers or central district energy boilers — presents a large market for professional engineering firms also. A large research university, for example, will have dozens, if not well over 100 boilers that heat and cool square footage in all climates throughout the year. The same boilers provide heating and cooling for data centers, laundry operations, kitchen steam tables in hospitals and dormitories.
“…The International Boiler and Pressure Vessel Code establishes rules of safety — relating only to pressure integrity — governing the design, fabrication, and inspection of boilers and pressure vessels, and nuclear power plant components during construction. The objective of the rules is to provide a margin for deterioration in service. Advancements in design and material and the evidence of experience are constantly being added…”
Many state and local governments incorporate the BPVC by reference into public safety regulations and have established boiler safety agencies. Boiler explosions are fairly common, as a simple internet search on the term “school boiler explosion” will reveal. We linked one such incident at the bottom of this page.

The 2023 Edition of the BPVC is the current edition; though the document is divided into many sections that change quickly.
Two characteristics of the ASME standards development process are noteworthy:
Only the proposed changes to the BPVC are published. The context surrounding a given change may be lost or not seen unless access to previous version is available. Knowledgeable experts who contribute to the development of the BPVC usually have a previous version, however. Newcomers to the process may not.
The BPVC has several breakout committees; owing to its longer history in the US standards system and the gathering pace of complexity in this technology.
We unpack the ASME bibliography primarily during our Mechanical, Plumbing and Energy colloquia; and also during our coverage of large central laundry and food preparation (Kitchens 100) colloquia. See our CALENDAR for the next online meeting, open to everyone.

The MIL-SPEC catalog and its evolution have had a significant impact on various industries beyond the military sector. Many civilian industries have adopted military standards as a benchmark for quality, reliability, and compatibility in their products and processes.
World War II Era:
The MIL-SPEC system traces its roots back to the World War II era when the U.S. military faced challenges in coordinating manufacturing efforts across multiple suppliers. To address these challenges, the military began developing specifications and standards that detailed the requirements for various equipment and materials, including dimensions, materials, performance criteria, and testing procedures.
Post-World War II:
After World War II, the MIL-SPEC catalog expanded significantly to cover a wide range of military equipment, ranging from electronics and aircraft components to clothing and food supplies. The standards were continuously updated and revised based on technological advancements, lessons learned, and evolving military needs.
Evolution into MIL-STD:
In the 1950s and 1960s, the MIL-SPEC system evolved into the Military Standard (MIL-STD) system to provide even more comprehensive and detailed specifications. MIL-STD documents incorporated a broader scope of requirements, including design criteria, quality control processes, and test methodologies. The MIL-STD system aimed to ensure consistent design and manufacturing practices across contractors and suppliers.
MIL-STD Transition to Commercial Standards:
Over time, the reliance on MIL-STDs started to decline, and there was a shift towards adopting commercial standards whenever possible. This transition allowed the military to benefit from the advancements and cost efficiencies of commercial technologies. However, certain critical military-specific standards, such as those related to security and specialized equipment, continued to be maintained within the MIL-STD framework.
DoD’s Transition to Performance-Based Specifications:
In recent years, the DoD has been moving away from prescriptive specifications (MIL-STDs) towards performance-based specifications. Performance-based specifications focus on defining the desired outcomes and performance requirements while allowing contractors greater flexibility in meeting those requirements. This approach encourages innovation, cost-effectiveness, and broader industry participation in military contracts.
The West Virginia University PRT (Personal Rapid Transit) system is a unique and innovative form of public transportation that serves the WVU campus and the city of Morgantown, West Virginia. The PRT system consists of a series of automated, driverless vehicles that operate on an elevated track network, providing fast and convenient transportation to key destinations on and around the WVU campus.
The PRT system was first developed in the 1970s as a solution to the growing traffic congestion and parking demand on the WVU campus. The system was designed to be efficient, reliable, and environmentally friendly, and to provide a high-tech, futuristic mode of transportation that would appeal to students and visitors.
The PRT system currently operates five different stations, with stops at key campus locations such as the Mountainlair Student Union, the Engineering Research Building, and the Health Sciences Center. The system is free for all WVU students, faculty, and staff, and also offers a low-cost fare for members of the general public.
The PRT system has been recognized as one of the most advanced and innovative public transportation systems in the world, and has won numerous awards for its design, efficiency, and environmental sustainability. It has also become an iconic symbol of the WVU campus, and is often featured in promotional materials and advertising campaigns for the university.
“Evaluation of the West Virginia University Personal Rapid Transit System” | A. Katz and A. Finkelstein (Journal of Transportation Engineering, 1987) This paper evaluates the technical and operational performance of the WVU PRT system based on data collected over a six-year period. The authors identify several issues with the system, including maintenance problems, limited capacity, and difficulties with vehicle docking and undocking.
“Modeling of the West Virginia University Personal Rapid Transit System” by J. Schroeder and C. Wilson (Transportation Research Record, 2002) This paper presents a mathematical model of the WVU PRT system that can be used to analyze its performance and identify potential improvements. The authors use the model to evaluate the impact of various factors, such as station dwell time and vehicle capacity, on the system’s overall performance.
“Evaluating the Effectiveness of Personal Rapid Transit: A Case Study of the West Virginia University System” by K. Fitzpatrick, M. Montufar, and K. Schreffler (Journal of Transportation Technologies, 2013) This paper analyzes the effectiveness of the WVU PRT system based on a survey of users and non-users. The authors identify several challenges facing the system, including low ridership, reliability issues, and high operating costs.
Energy 400: Codes and standards for energy systems between campus buildings. (District energy systems including interdependence with electrical and water supply)
A different “flavor of money” runs through each of these domains and this condition is reflected in best practice discovery and promulgation. Energy 200 is less informed by tax-free (bonded) money than Energy 400 titles.
Some titles cover safety and sustainability in both interior and exterior energy domains so we simply list them below:
There are other ad hoc and open-source consortia that occupy at least a niche in this domain. All of the fifty United States and the Washington DC-based US Federal Government throw off public consultations routinely and, of course, a great deal of faculty interest lies in research funding.

We break down our coverage of laboratory safety and sustainability standards thus:
Laboratories 100 covers a broad overview of the safety and sustainability standards setting catalogs; emphasis on titles incorporated by reference into public safety laws.
Laboratories 200 covers laboratory occupancies primarily for teaching
Laboratories 300 covers laboratories in healthcare clinical delivery.
Laboratories 400 covers laboratories for scientific research; long since creating the field of environmental health and safety in higher education and a language (and acronyms of its own: CSHEMA)
In the most recent fiscal year, the National Institutes of Health had a budget of approximately $47.7 billion. A substantial portion of this budget is allocated to research at colleges and universities. Specifically, about 83% of NIH’s funding, which translates to roughly $39.6 billion, is awarded for extramural research. This funding is distributed through nearly 50,000 competitive grants to more than 2,500 universities, medical schools, and other research institutions across the United States
The cost to build a “standard” classroom runs about $150 to $400 per square foot; a scientific research laboratory about $400 to $1200 per square foot.
Laboratories 500 is broken out as a separate but related topic and will cover conformity and case studies that resulted in litigation. Both Laboratories 200 and 400 will refer to the cases but not given a separate colloquium unless needed.

“Evaluating the Efficacy of Laboratory Hazard Assessment Tools for Risk Management in Academic Research Laboratories” – This study from 2021 evaluated the effectiveness of various laboratory hazard assessment tools in academic research laboratories, and found that a combination of tools and approaches may be most effective for managing risks.
“A Framework for Assessing Laboratory Safety Culture in Academic Research Institutions” – This 2020 study developed a framework for assessing laboratory safety culture in academic research institutions, which can help identify areas for improvement and promote a culture of safety.
“Enhancing Laboratory Safety Culture Through Peer-to-Peer Feedback and Coaching” – This 2020 study found that peer-to-peer feedback and coaching can be an effective way to enhance laboratory safety culture, as it encourages open communication and feedback among colleagues.
“Assessing the Effectiveness of Laboratory Safety Training Programs for Graduate Students” – This 2019 study evaluated the effectiveness of laboratory safety training programs for graduate students, and found that interactive and hands-on training was more effective than traditional lecture-based training.
“Improving Laboratory Safety Through the Use of Safety Climate Surveys” – This 2018 study found that safety climate surveys can be an effective way to improve laboratory safety, as they provide insight into employee perceptions of safety culture and identify areas for improvement.
These recent research findings suggest that laboratory safety culture can be improved through a variety of approaches, including hazard assessment tools, peer-to-peer feedback and coaching, interactive training, and safety climate surveys. Some of these findings will likely set the standard of care we will see in safety standards incorporated by reference into public safety regulations.

Today we will poke through a few proposals for the 2021/222 revision of the International Code Council’s Group A Codes. For example:
IFC § 202 et. al | F175-21| Healthcare Laboratory Definition
IBC § 202 et. al | E7-21| Collaboration Room
IBC § 1110.3 et. al | E143-21| Medical scrub sinks, art sinks, laboratory sinks
. . .
IFGC § 403, etl al| G1-21| Accessibility of fuel gas shut off valves
IBC § 307 Tables | G36-21| For hazardous materials in Group B higher education laboratory occupancies
IBC § 302.1 et. al | G121-21| Separation from other nonlaboratory areas for higher education laboratories
And about 20 others we discussed during the Group A Hearings ended last week. We will have until July 2nd to respond. The electrotechnology proposals will be referred to the IEEE Education & Healthcare Facilities Committee which is now preparing responses to this compilation by Kimberly Paarlberg.

Today we break down action in the literature governing the safety and sustainability of instruction and research laboratories in the United States specifically; but also with sensitivity to similar enterprises in research universities elsewhere in the world. “Everyone” has an iron in this fire:
…and ISEA, AWWA, AIHA, BIFMA, CLSI, LIA, IAPMO, NSF, UL etc. among ANSI accredited standards developing organizations…
..and addition to NIST, Federal code of Regulations Title 29, NIH, CDC, FEMA, OSHA etc
…and state level public health regulations; some of them adapted from OSHA safety plans
Classroom and offices are far simpler. Laboratories are technically complicated and sensitive area of concern for education communities not only responsible for the safety of instructional laboratories but also global communities with faculty and staff that must simultaneously collaborate and compete. We have been tip-toeing through the technical and political minefields for nearly 20 years now and have had some modest success that contributes to higher safety and lower costs for the US education community.
