Cross-cutting Issues

This paper describes the uses of a cooperative control algorithm between on-board vehicle
computers and signal control computers that are connected by low-latency Dedicated Short-
Range Communications (DSRC) wireless into a single control loop. Deployed use cases include
environmental vehicle engine control, Cooperative Intersection Collision Avoidance System -
Violations (CICAS-V), advanced actuated traffic signal control and adaptive traffic signal
control.

The Intelligent Transportation Systems (ITS) Professional Capacity Building (PCB) Program is currently working to identify ITS core competencies in order to understand what determines proficiency in ITS. Core competencies represent the minimum set of core knowledge, skills and abilities (KSAs) required to function effectively in a specific field. This paper examines several projects, both completed and on-going, that have examined the core competencies for Management and Operations (M&O). But how do the core competencies for M&O relate to the core competencies for ITS? After review of multiple definitions of M&O and ITS, ITS is the technology, while Management and Operations is the application of the technology.  In other words, ITS is the principle tool used to support the needs of M&O. Therefore, should be considered a subset of M&O. PCB. The key to the roadmap was solidifying the core competencies for M&O professionals.

it seems thatITSIn July 2011, a roadmap was developed for operations.  Assuming agreement that competencies for M&O are endorsed, then the ITS PCB program can extract the ITS core competencies from the overall M&O ones. Once that activity is completed, the ITS PCB program plans to develop an outline of the baseline curriculum that is necessary to obtain various levels of ITS proficiency. The curriculum will specify courses to be taken within certain tracks to become recognized as being particularly proficient or expert in a specific ITS technology or other area.  ITS should be considered a subset of M&O.

Connected Vehicle and Active Traffic Management (ATM) are the innovative traffic management strategies emphasizing Information Technology (IT)-based intelligent vehicle and infrastructure, advanced control technology, and system integration to address the grand challenges in transportation systems, such as severe congestion, increased risk of traffic incidents, and traffic pollution. Connected Vehicle aims to facilitate better traffic operations through two-way wireless communication of vehicle-to-vehicle and vehicle-to-infrastructure. ATM is an operational approach for optimal performance of highway system through various advanced control strategies. Seamless integration of Connected Vehicle and ATM strategies can generate significant benefits to optimize overall traffic system operations. This paper provides a comprehensive review on the state of the art and the practice of Connected Vehicle and ATM strategies. The study findings are helpful to better understand their fundamental control and operation mechanisms, practical applications, system benefits, and operational challenges.

ITS Standards development has changed over the past few years requiring a need to update and improve previous ITS Standards Training courses. Several ITS Standards are now available as later version standards and some ITS Standards that have been developed with a Systems Engineering Process (SEP) contain additional content that helps deployers ensure that they can implement a system that is interoperable, interchangeable, and conformant to ITS Standards. Such ITS systems will be able to provide information and services to other systems and use exchanged information and services to operate together effectively. As a result, there is a renewed interest within the ITS community for assistance with procuring and testing when deploying systems implementing ITS Standards. The ITS Standards Program and ITS Professional Capacity Building Program (ITS PCB) are undertaking a project to develop a new set of training materials that emphasize the acquisition, implementation, and testing of ITS Standards.

Winter road maintenance is one of the biggest challenges for agencies responsible with providing safe environments for the public, and it has been a major growth area for ITS systems in the past few years. At the same time, budget issues have forced agencies to do ‘more with less’ and the use of smarter, more intelligent systems such as mobile data collectors have contributed to address these issues. Manufacturers of these systems are staying on the cutting edge of technology and adapting their systems to the needs and requirements of states and other winter road maintenance agencies, both in terms of increased capabilities and reduced costs.

The Maintenance Decision Support System (MDSS), adopted by the majority of states with
severe winter weather, has introduced a more scientific approach to the management and
direction of snow plows, by utilizing expert weather service providers to give route specific
weather reports and more precise application rate recommendations tailored to the specific
weather conditions being experienced.
