Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

  220      8 Conclusion Cloud‐computing technologies are the next‐generation architecture. These technologies have created  excitement in the IT and business world by promising to deliver a wide range of benefits. Gartner  estimated that the cloud market will surpass $148.8 billion by 2014. Nonetheless, cloud technologies  remain for many an unfamiliar concept. Therefore, if cloud‐computing technology is to be adopted by  state DOTs to support their EIPs, there is a need for state DOTs to have a clear understanding of the  various factors associated with the adoption of cloud‐computing technology.    Cloud‐computing technologies have already greatly impacted businesses in many areas, such as banking,  the automobile sector, education, logistics, wholesale, retail, and health care. These technologies are  also emerging in the manufacturing industry and supply chains, transforming traditional business  models and helping with product innovation, business strategy, collaboration, and efficient networks.  State DOTs are in a similar situation. They mostly take traditional approaches to supporting their EIPs in  various business areas. While state DOTs may be willing to explore further and adopt next‐generation  cloud architecture to improve performance, reduce cost, and improve agility and information visibility,  their possible engagement is limited by many factors—legal, cultural, organizational, and financial  restrictions, as well as security restrictions sometimes outside of state DOT control.   Fortunately, the adoption of next‐generation cloud architecture differs from traditional architecture  redesign. Rather than requiring a complete redesign of a DOT EIP, next‐generation cloud architecture  can be implemented little by little, upgrading EIP applications one by one without disrupting an already  established and well‐functioning EIP or necessitating a large amount of funding to implement a new  system and train personnel.  By starting small, state DOTs can test the application of next‐generation  technologies to their EIPs and get acquainted with their benefits and challenges. DOTs can become more  knowledgeable about next‐generation technologies without risking or compromising their operations,  showcase the potential and savings that these technologies provide, and compare the experience to the  remedies currently applied to traditional architecture such as outsourcing.    In addition to trying new EIP technologies in house, state DOTs should adopt a more open approach to  EIP design.  By adopting next‐generation cloud technologies, state DOTs could greatly benefit from  sharing their experience of migrating EIP applications to the cloud with other DOTs.  Sharing is typically  accomplished through communicating lessons learned and peer‐to‐peer exchange, but cloud  technologies, such as containerization, offer a much more extensive way of sharing. Cloud technologies  allow cloud EIP applications developed by one state DOT to be shared, tested, and reused easily by  other state DOTs without having to incur the redesign cost, just by moving the applications to another  cloud private network or another cloud environment.    The kind of technology sharing described above would allow cloud EIP applications to become more  robust as they would be collaboratively designed and tested by multiple state DOTs, each with different  requirements.  One can envision the emergence of a cloud marketplace where cloud EIP applications  could be published and purchased. This would allow state DOTs with limited funding to purchase  complex EIP applications that they would not have the funds to develop on their own.  Of course, such  an approach to developing and maintaining DOT EIPs is far removed from the current acquisition  process followed by state DOTs when purchasing IT solutions, but it is the state of the practice in the  cloud industry.  Transportation organizations may want to consider this option and establish the  foundations needed for the development of a transportation cloud environment where state DOTs 

  221      could share data and develop EIP applications without violating legal requirements or compromising  their interests and security.

TRB's National Cooperative Highway Research Program (NCHRP) Web Only Document 241: Development and Management of Sustainable Enterprise Information Portals documents the research approach and methodology to develop NCHRP Research Report 865: Guidance for Development and Management of Sustainable Enterprise Information Portals. The guidance addresses the development and management of effective Enterprise Information Portals (EIPs) at state departments of transportation.

EIPs have become key tools for transportation agencies as they make available information about the transportation system and the agency’s activities. Such EIPs must be curated; that is, there are people responsible for establishing the portal architecture, ensuring the quality of information and data, and maintaining the reliability of access. The report is intended to enhance agency personnel’s understanding of the value, uses, design, and maintenance of EIPs, and the design principles, management practices, and performance characteristics that will ensure that a DOT’s EIPs effectively and sustainably serve its users and the agency’s mission.

A PowerPoint presentation on enterprise information portals (EIPs) for transportation agencies supplements the report. Use case diagrams referenced in the report are available in Visio format through a zip file.
