(C)onnected & (A)utomated (V)ehicle Code

Satire on Steam Coaches (1831) / H. T. Alken

The CSA America Standards organization has launched a new best practice title — CSA T150 Connected & Automated Vehicle Code — that may, at the very least, guide the safety and sustainability agenda of many large research universities that have transportation service units.   Many governments direct research funding toward transportation so this product may inform the practicality of academic research.

The CSA Group announcement, made through ANSI’s Project Initiation Notification platform, is paraphrased below:

Project Need: To support innovation and deployment in the field of connected and autonomous vehicles by providing infrastructure requirements for the installation and safe operations of CAVs and corresponding infrastructure in the North American context.  

Stakeholders: This proposed Code is being developed at the request of industry and manufacturers. It will provide the industry with the technical requirements and standards of safe operation of CAVs. This will meet the strategic needs of the following key interests:

(a) Ensuring that the latest innovative/technology/safety features are available for users,

(b) Addressing needs of regulators by providing suitable requirements;

(c) Supporting certification bodies.

The connected and automated vehicle (CAV) code specifies infrastructure requirements for CAVs operating or intended to operate in both on-road and off-road environments in order to address public safety, security, and privacy challenges. The code includes, but is not limited to, physical and digital infrastructure. Consideration is given to cybersecurity, interoperability, data management, data privacy, data integrity, human aspects, and accessibility. The CAV code is intended to primarily address issues related to public safety, security, and privacy in conjunction with detailed knowledge of the legal, regulatory, and technological landscape, and ensuring compliance with all relevant and applicable law. The CAV code is not intended as a design specification nor as an instruction manual for untrained persons.

According to the public comment page this title was open for consultation for less than 30 days.

This is an ambitious undertaking and certain to inspire competition among competitor conformance and certification organizations.   Accordingly, we will follow the developmental path of the proposed “Code”.   We encourage direct participation in the CSA Group’s standards development program by students, faculty and staff in the education industry.

Public Review

Standards Michigan will continue to be a resource for education facility managers, academic researchers and any other final fiduciary (user-interest) in the public or private sector who need cross-cutting perspective.  This title appears on the standing agenda of our periodic Mobility colloquia.  See our CALENDAR for the next online meeting; open to everyone.

Abstract:  With the rapid deployment of smart technologies and the growing complexity in our modern society, there is a huge demand for coordination in day-to-day operation of the critical infrastructure networks. The coordination between water and electricity networks particularly stands out and is urgently demanding as (i) water system is one of the most energy-intensive critical infrastructure, and (ii) water unavailability, if experienced, swiftly translates into a health, safety, and national security concern. This paper proposes a comprehensive day-ahead optimization framework for joint operation of the interdependent power and water systems. Different from the conventional paradigms where the power and water systems are independently and individually operated by their respective operators, the proposed optimization framework integrates the Optimal Power Flow (OPF) models in power grids with innovative models of the water distribution systems. The nonlinear hydraulic operating constraints in the proposed optimization models are linearized, resulting into a mixed-integer linear programming (MILP) model formulation. The proposed framework is applied to three 15-node water distribution systems, operated within the IEEE 9-bus test system. The simulation results demonstrate a significant cost saving that will be achieved when the proposed approach is applied for joint operation of power and water networks.

A BIM-Based Coordination Support System for Emergency Response

A BIM-Based Coordination Support System for Emergency Response

Department of Architectural Engineering, The Pennsylvania State University

Abstract: In fire emergencies, timely communication with on-site coordinators and accurate localization of first responders facilitates effective task assignment and resource allocation in harsh, low-visibility environments. Building information modeling (BIM) is widely accepted in the architecture, engineering, and construction industries as a central repository of building information. It could provide both the geometric building data and semantic information; however, the convenient linkage and integration with indoor location technologies for emergency purposes have not been addressed according to the authors’ knowledge.

A stand-alone BIM-based indoor location (BIMIL) framework and portal were designed and tested to enable the automatic extraction, transformation, and visualization of BIM-related data for public safety purposes in this study. Based on current information technology, this research reduces the gap in cross-application by supporting indoor location to overcome the primary shortcoming of existing indoor building models. Eliminating the need for specific software and skill in data processing, this portal will support on-site coordinators’ importation of BIM files, allowing them to convert those files into processed and visualized indoor information containing key yet simplified geometric building data and essential emergency-related information such as fire rating hours, egresses, and hazardous materials. Additionally, the indoor location data can be integrated into a generalized 3D building model to support decision-making activities and management tasks in the field.

Wiring Fire Prevention in Hospitals

Localized fire ignition hazard in branch circuits, cords and connected equipment

Electrical Engineering Department, Sapienza Università di Roma
Italian National Fire Department

Abstract.  In electrical power systems, the fire ignition can be originated by incident energy of faults. Faults involve overheating, arcing and burning for all the wiring exposed to mechanical damage and other insulation stresses especially wiring connected by flexible cords and cables. The mechanical damage of the stranded bare conductors can degrade the effective sizing of the total cross section, causing anomalous conditions of local overcurrent. To highlight the local incident energy in case of fault, the parameters steady current and transient current densities can assist in analyzing the event. The conductors size reduction, degrading locally the thermal withstand capability, makes ineffective the protection coordination amplifying the anomalous effect of current no detectable adequately by overcurrent protective devices. The faulted cords remain so energized and present electric shock and fire hazards. Generally and especially in strategic buildings as hospitals, preventing ignition is better than promptly extinguishing. An efficient protection can be achieved by integration of active and passive techniques : by adoption of the special device Arc-fault Circuit Interrupter (AFCI) that recognize the arcing; by wiring the circuits, particularly extension cords, with Ground-Fault-Forced Cables, GFFCs, that convert faults into ground faults easily protected by ground fault protective devices (GFPDs).
