At the beginning of the twenty-first century, the National Park Service (NPS) faces a daunting challenge in its mission: to preserve and protect the natural and cultural resources within the nearly 400 national park units while providing transportation systems adequate to accommodate growing visitation-up from 220 million recreation visits in 1980 to more than 277 million in 2002, an increase of more than 25 percent. Because one traditional response-building additional transportation infrastructure-is no longer considered a sustainable or desirable solution to park access, congestion, and environmental problems, meeting this challenge requires careful transportation planning and consideration of new methods and technologies. One such set of technologies, Intelligent Transportation Systems (ITS), represents practical alternatives to building new or expanded roads as the only solution to meeting growing travel demand. NPS has already deployed ITS technologies in several parks; experiences to date indicate that there are many other circumstances under which ITS has the potential to help NPS better manage its transportation systems.

This study, performed by the U.S. Department of Transportation John A. Volpe National Transportation Systems Center, evaluates the feasibility of a shuttle system that would connect south Baltimore and Fort McHenry National Monument and Historic Shrine with the Inner Harbor area of the city of Baltimore. In addition to examining the creation of a new service, this study also investigates the possible incorporation of a shuttle system into existing and/or proposed transit systems, specifically the Charm City Circulator.

At 10:50 a.m. on October 13, 2003, a 1992 Neoplan USA Corporation 49-passenger motorcoach, owned and operated by the First Baptist Church of Eldorado, Texas, was traveling eastbound on Interstate 20 neat Tallulah, Louisiana.

This memorandum documents a field test conducted on October 26, 2000 in Philadelphia, PA for the proposed Independence Transportation Center.

Stock modeling is the process of estimating the number of pieces of equipment in service in a given year manufactured in each of all relevant prior years.

Increased visitation at Chimney Rock in the San Juan National Forest in southwest Colorado has led to increasing interest in the addition of a shuttle system. Piloting a shuttle system at Chimney Rock is a relatively low-cost option that the USFS could pursue along with its partners to test how an alternative transportation system may help to accommodate the increase in visitation and its impacts to safety and resource concerns. Piloting a shuttle for two full seasons of regular visitation and pertinent special events would be a prudent approach to gaining valid information that can be used to determine what type of permanent alternative transportation system could be implemented. Ideally, the shuttle system should run daily and at selected special events.

Identifying applications that can reduce fuel consumption and emissions from surface transportation is an important strategy in solving transportation's environmental dilemma. The U.S. Department of Transportation (U.S. DOT) has set out to investigate the problem through several initiatives, one of which is connected vehicle research. The purpose of this report is to document the state of the practice for applications that have demonstrated environmental benefits through ITS technologies, or have the potential to do so, and identify opportunities to leverage existing research. The findings outlined in the report will assist the U.S. DOT in planning and implementing the Applications for the Environment: Real-Time Information Synthesis (AERIS) Program. The findings will also provide the basis for identifying opportunities to further examine and research applications for improving environmental decisions by public agencies and consumers and for improving environmental outcomes through ITS.

Momentum has been building over the past twenty months to address transportation, growth, development and quality of life issues on Cape Cod and the Islands. Starting with the Cape Cod Transit Summit in February 2000 and the formation of the Cape Cod Transit Task Force, region-wide priorities regarding public transportation on Cape Cod and the Islands, and goals and objectives for guiding short-range planning have been identified. There is consensus thatimproved public transportation services are needed both to mitigate seasonal traffic congestion and to meet the mobility needs of the year-round transit-dependent population.

The Federal Highway Administration (FHWA) established the Carbon Sequestration Pilot Program (CSPP) in 2008 to assess whether a roadside carbon sequestration effort through modified maintenance and management practices is appropriate and feasible for state Departments of Transportation (DOTs) when balanced against ecological and economic uncertainties.

A flight experiment was conducted to assess human factors issues associated with pilot use of traffic displays for approach spacing. Sixteen multi-engine rated pilots participated. Eight flew approaches in a twin-engine Piper Aztec originating in Sanford, ME, and eight flew approaches in the same aircraft originating in Atlantic City, NJ. The spacing target was a Cessna 206. The traffic display was either a Garmin International MX-20 (the "Basic" Cockpit Display of Traffic Information, or CDTI) or an MX-20 modified with features to help the pilot monitor the closing rate, the range and ground speed of the traffic-to-follow, and ownship ground speed (Range Monitor). Two other Equipment conditions were Baseline and Autopilot. Pilots successfully used the displays to maintain the assigned spacing on visual and instrument approaches.

In this annual report, Traffic Safety Facts 2001: A Compilation of Motor Vehicle Crash Data from the Fatality Analysis Reporting System and the General Estimates System, the National Highway Traffic Safety Administration (NHTSA) presents descriptive statistics about traffic crashes of all severities, from those that result in property damage to those that result in the loss of human life.

Area navigation (RNAV) and required navigation performance (RNP) procedures are fundamental to the implementation of a performance based navigation (PBN) system, which is a key enabling technology for the Next Generation Air Transportation System (NextGen). As new RNAV and RNP procedures are developed, they are published as chartsfor use by appropriately qualified pilots. These chartsand procedures describe paths that must be flown preciselyfor improveduse ofairspace and safety.In this document, we considerhow chartsfor both conventional and PBN procedures are designedfrom ahuman factors perspective.First, we document current charting challenges and mitigation strategies. Next, wedescribe areview ofprocedures thatwas done to discover whichfeatures wererelated to difficulty of use or visual complexity. The moredifficult instrument approachcharts depict procedures with moreflight paths, path segments, and radius-to-fix legs.Standard instrument departure procedures that are more difficult show more flight paths. Standard terminal arrival route procedures that are more difficult have more total altitude constraints and path segments.Finally, we describe the process for designing and implementing new instrument procedures, whichinvolves significant coordination both inside and outside the government

The Interagency Transportation, Land Use, and Climate Change Pilot Project utilized a scenario planning process to develop a multi-agency transportation- and land use-focused development strategy for Cape Cod, Massachusetts, with the intention of achieving a reduction in future greenhouse gas emissions and considering the potential impacts of sea-level rise on the region. This scenario was developed through a process of data collection, scenario development by a consultant and by regional and local government during a workshop, and scenario assessment. The outcomes of this scenario planning process will inform and support the region's long-range transportation planning and other related efforts, as well as the planning efforts of local, state, and federal agencies. Project members collaborated to document the project's steps and to offer significant observations and recommendations that can inform future applications.
