The growth of wireless technologies provides great promise for current and future ITS communications infrastructure deployments.  Knowing what technologies to deploy is critical to
the long-term success and cost of an ITS deployment.  Traditionally, ITS networks have been based on a mix of private or leased wired infrastructure that uses copper or fiber optic cabling. This paper discusses the high costs associated with this type of deployment and how wireless technologies could reduce some of these costs.  An overview of currently available wireless technologies that are most applicable to ITS designs is presented.  Significant design issues that must be considered are discussed, including security, system reliability, total cost of ownership, and interoperability and expandability.

New technologies are bringing Automated Freight Systems (AFS), which aim to reduce congestion, mitigate environmental impacts and enhance public safety, to fruition. The financing and deployment issues of AFS differ from other Intelligent Transportation System applications. This paper briefly introduces major concepts of AFS, which include Automated Rail Systems (ARS), Automated Truck Systems (ATS) and Automated Pipeline Systems (APS).
. The financing strategies for these concepts are discussed, in which the government subsidies play an important role through the use of public-private partnership. Economies of scale and externalities of the current and new systems are discussed. In the discussion of the deployment of AFS, it is suggested that deployment schemes are highly correlated with financing strategies.

ITS has great potential to minimize the impact of our expanding transportation system on the
environment. One of the tools to make ITS a reality is the development of ITS architectures to guide ITS planning and project development. The National ITS Architecture provides a
foundation for the development of ITS plans and projects and it has components that provide
insights into environmentally friendly ITS features. This paper will explore the features of the
National ITS Architecture that contribute the most to the planning and development of ITS that is environmentally friendly. The paper will draw attention to those Architecture features that reduce greenhouse gas emissions, reduce the use of non-renewable resources, and limit the impact of the transportation system on environmental resources such as land use and hazardous materials. The paper will also make suggestions promoting the use of these features by stakeholders in their ITS planning and deployment.

Global warming, brought about increased greenhouse gas (GHG) concentrations, is a
significant threat to the planet. Transportation activities account for 28% of all GHG emissions
in the U. S. Recent climate change literature has focused on three primary strategies for reducing
GHG emissions from the surface transportation sector – improving the fuel economy of vehicles,
reducing the carbon content of the fuel used, and decreasing the amount of driving or Vehicles
Miles Traveled (VMT). This paper addresses a fourth strategy – improving the operational
efficiency of the surface transportation network through the implementation of transportation
systems management and operational (TSMO) strategies and the supporting ITS technologies.
The potential benefits of TSMO for reducing GHG emissions and adapting to climate change are
discussed along with several issues (e.g., need for models and analytical tools to estimate GHG
reductions, potential for latent demand resulting from improved roadway efficiency)

Due to economic, environmental and political reasons, there is an increasing demand for zero-emission vehicles. With the wide-scale deployment of electric car systems, a variety of parties with conflicting interests will be interacting, and there will be incentives for dishonest behavior. As a consequence, new technical challenges which are related to IT security and embedded security arise in the context of electric vehicle systems. For instance, payment and metering needs to be secured, privacy needs to be preserved, and the infrastructure needs to be protected. This work investigates for the first time the security threats that must be addressed in intelligent transportation systems, discusses possible solutions, and presents the benefits that IT security provides in this context.
