      <title>A planning tool for evaluating vehicles miles travelled and traffic safety forecasts of growth management scenarios: A case study of Baton Rouge and New Orleans</title>
      <link>https://trid.trb.org/View/1503250</link>
      <description><![CDATA[This study describes an adaptable planning tool that examines potential change in vehicle miles travelled (VMT) growth and corresponding traffic safety outcomes in two urbanized areas, Baton Rouge and New Orleans, based on built environment, economic and demographic variables. This model is employed to demonstrate one aspect of the potential benefits of growth management policy implementation aimed at curbing VMT growth, and to establish targets with which to measure the effectiveness of those policies through a forecasting approach. The primary objective of this research is to demonstrate the need to break with current trends in order to achieve future goals, and to identify specific policy targets for fuel prices, population density, and transit service within the two study regions. Models indicate based on medium growth scenarios, Baton Rouge will experience a 9 percent increase in VMTs and New Orleans will experience 10 percent growth. This translates to corresponding increases in crashes, injuries and fatalities. The paper provides forecasts for planners and engineers to consider an alternative future, based on desired goals to reduce VMTs and therefore improve safety outcomes. A constrained-forecast model shows a cap on VMTs and crash rates is achievable through policy that increases fuel prices, population density and annual transit passenger miles per capita at reasonable levels through a growth management approach.]]></description>

      <title>Planning for Container Growth along the Houston Ship Channel and Other Texas Seaports</title>
      <link>https://trid.trb.org/View/1457025</link>
      <description><![CDATA[Study 0-5068 examined corridor improvement initiatives at all Texas seaports contemplating future container operations, with a primary focus on rail systems and current facilities under the Port of Houston Authority (POHA). This is the final study report and first estimates the volume of containers that could be handled by Port of Houston (POH) terminals from 2004 to 2020. It then describes the Port Terminal Railroad Association (PTRA), which operates its own network and serves more than 173 major industrial sites and terminals along the Houston Ship channel. Next, it examines Houston issues related to highway movement of containers from the POHA terminals. The pattern of distribution centers in Houston serving as the most common first landside destinations for POHA containers is then described. A survey of the Houston dray industry and its driver workforce is then reported. Since other deep-water Texas Gulf locations may have container terminals in future, consideration is given to the proposed terminals at Corpus Christi and Texas City. Finally, conclusions and recommendations from the two-year study are given, emphasizing issues most likely to impact transportation planning and programming in Texas.]]></description>

      <title>A Guide to Building and Retaining Workforce Capacity for the Railroad Industry</title>
      <link>https://trid.trb.org/View/1372603</link>
      <description><![CDATA[This report uses a comprehensive review and analysis of employee characteristics of the railroad industry—including an assessment of past trends and current forecasts and a detailed gap analysis of employee supply and demand—to formulate a series of competency models describing workforce requirements for the passenger and freight railroad industry. The report also presents a strategy for improving employee retention and develops recommendations for enhancing educational programs designed to attract new employees to the industry—employees who meet the demands of these competency requirements. The competency models presented in the report focus on performance needs rather than credentials, establishing criteria for exemplary rather than minimal characteristics. These models encompass the four major categories of employment within the industry as well as subcategories providing detail for each. This report serves as a guide to the industry on how to respond to the long-term need for building an effective workforce to support the growth of the rail industry, both passenger and freight, in a changing and evolving environment. Used as a guide, this report can assist the railroad industry as a whole, from management to human resource recruiters, in building a quality workforce for the future. It will also be useful to college and university educators as they formulate curricula and build training programs to attract new workers into the industry.]]></description>

      <title>Expanded Transportation Performance Measures to Supplement Level of Service (LOS) for Growth Management and Transportation Impact Analysis</title>
      <link>https://trid.trb.org/View/1223021</link>
      <description><![CDATA[Many jurisdictions in Florida are moving toward multimodal transportation systems that provide users with viable travel options in an effort to minimize the economic, social, and environmental costs that have been associated with a purely vehicular system. To support this transition, a set of performance measures is needed that will supplement the vehicle-based Level of Service (LOS) that has been the primary tool within project impact analysis. This project developed a framework for assisting agencies in selecting a set of performance measures that are consistent with their overall goals and the quality of life that the community desires. An extensive list of performance measures was synthesized from the literature and categorized into groups according to several typical community and agency goals that they may support. Since there are numerous performance measures that can support each goal, several evaluation criteria were listed that can be used by a local agency to assess each measure in light of the agency's goals, policies, and resources. These criteria consider the type and quality of data available to the agency, the compatibility of the measures with other agency processes, as well as the degree to which a measure encourages multimodal transportation. The report provides an example of how an agency could apply these criteria in order to select performance measures consistent with its goals and capabilities. The review systems for four Florida communities that have implemented successful multimodal areas are described in terms of their comprehensive plan, land development code, and project impact review. Land use mix and pedestrian environment measures were strongly favored by the communities documented in these system-level case studies, with multimodal choice strongly prioritized over congestion management. Finally, two development scenarios are created and studied using several performance measures to compare how different land use form affects the calculation of performance measures. A comparison of the impact is made based on whether measures support congestion management or mobility choice. The two development scenarios yield similar results when using congestion management as the primary agency objective, but show significant differences in their ability to support multimodal systems.]]></description>

      <title>Time to Move On, Says Higgins</title>
      <link>https://trid.trb.org/View/1101262</link>
      <description><![CDATA[The United Kingdom's Network Rail (NR) recently began unveiling its strategic plans for improving efficiency and transferring control of NR from central  to local management teams. The views of NR's Chief Executive Christopher Higgins are presented in this article in regard to these plans. Higgins advocates gleaning prior business models for information, and then using that information in a completely new model. Pilot projects for the change from central to local management are due to start this month. In addition, NR's first route managing directors are being recruited. One of NR's biggest challenges this year will be adjusting to growth, which includes matching supply and demand.]]></description>

      <title>Guide for Review and Assessment of Local Mobility Plans: A Proposed Practice</title>
      <link>https://trid.trb.org/View/916088</link>
      <description><![CDATA[This research supports implementation of mobility planning requirements in Florida’s transportation and growth management legislation, including the Community Renewal Act, HB 697 and HB 7135. The final report and spreadsheet template set forth a proposed practice to guide the review of mobility plans related to these requirements. These materials are also useful for review of local government comprehensive plan amendments aimed at mitigating transportation deficiencies on the Strategic Intermodal System. This proposed practice applies a series of criteria that represent professionally-accepted best practices for mobility planning and transportation corridor management. The selected criteria are identified in the literature as practices that support the use of alternative modes, advance corridor management objectives for major highway corridors, reduce vehicle miles of travel (VMT), and enhance the multimodal environment. Advancing these criteria through the mobility planning process will also promote more energy-efficient land use patterns and transportation systems that reduce greenhouse gas emissions. The spreadsheet template allows local governments and reviewing agencies to assess the proposed mobility plan based upon a point system related to relevant criteria. Weights are assigned by the user to reflect the relative importance of specific criteria to the proposed plan, including a weight of zero that allows users to eliminate criteria from the assessment that are not at all applicable in the local context.]]></description>

      <title>Co-Evolution of Transportation and Land Use: Modeling Historical Dependencies in Land Use and Transportation Decision-Making</title>
      <link>https://trid.trb.org/View/914782</link>
      <description><![CDATA[The interaction between land use and transportation has long been the central issue in urban and regional planning. Models of such interactions provide vital information to support many public policy decisions, such as land supply, infrastructure provision, and growth management. Both the transportation and land use systems exhibit historical dependencies in policy decisions. For instance, the expansion of a roadway today will change travel demand patterns, and make certain other roads more or less likely to be expanded in the future. A specific land supply decision made at one point in time, by changing the relative attractiveness of other areas in the region, can have a profound impact on future land supply decisions. Today’s land use decisions clearly influence future transportation policies and vice versa. This project examines the land use-transportation interaction from an evolutionary perspective — once a certain set of goals are determined and pursued by politicians and planners, their land supply and transportation investment decisions are, to a large extent, driven by their previous decisions and supply-demand dynamics in the urban system. Built upon this recognition of historical dependency and a transportation network growth model previously developed by the P.I., a model of the co-evolution of land use and transportation is proposed in this project. Different from existing integrated land use and transportation models that assume exogenous network investment decisions, the co-evolution model considers both land use growth and transportation network growth as endogenous and market-driven. The central research question is how market and policies translate into transportation facilities and land use developments on the ground. The co-evolution model achieves an Urban Growth Equilibrium, which is a useful concept for planning and policy analysis. An agent-based simulation approach is employed to integrate an existing land use model and the transportation network growth model.]]></description>

      <title>Growth Management and Sustainable Transport: Do Growth Management Policies Promote Transit Use?</title>
      <link>https://trid.trb.org/View/882205</link>
      <description><![CDATA[Although the concept of sustainability is somewhat elusive in the sense that it is defined and understood differently in different contexts, transit is typically considered a more sustainable transport mode.  One critical question regarding urban transit is how do we encourage its use?  In this paper, the authors focus on the effects of growth management policies on mode choice and transit use.  WThe authors discuss and empirically analyze whether or not state-level growth management efforts contribute to promoting transit use and through what causal mechanisms. The authors argue that theoretically, state-level growth management policies should effectively increase transit use in two critical ways: first, by limiting core abandonment and accommodating potential increases in population (potentially avoiding unnecessary or fringe development); and second, by directing new development into areas where transit systems are already well established.  The authors test this idea by analyzing 95 metropolitan areas across the U.S.; 16 within growth management jurisdiction, and 79 outside of growth management jurisdiction.  The authors find that metropolitan areas that were contained within growth management program jurisdiction showed a statistically significant improvement in the percentage of commuters using transit.  The results of this empirical analysis on causality however, suggest that the improvement is more likely due to an increase in occupancy rates (limiting core abandonment and potentially avoiding unnecessary development) rather than in shifting the location of new development to transit areas.]]></description>

      <title>Competitiveness, Growth and Logistics Implications: The Case of the Port of Genoa</title>
      <link>https://trid.trb.org/View/868466</link>
      <description><![CDATA[In the current world economic framework - characterized by an intense globalisation and informatization process - the phenomenon known as "death of distance" shows its effects in the transport industry as well. Therefore, the market boundaries broaden, ending up in the well-known results of hinterland overlapping and competition intensification. After an analysis of relevant reasons for port competitiveness studies, the paper aims at assessing the current and coming competitive positioning of the port of Genoa within the Mediterranean basin. It also indicates possible strategies aimed at maintaining a competitive position with respect to main competitors, at least in terms of a constant markets share. More in depth, it seems that successful strategies should address the improvement of the whole set of port, transport and logistics services, actually unavoidable for an efficient and complete port function. The paper ends with an outline of the logistics implications linked to port development, both as a cause and a consequence; of traffic increase and investigates the basic requirements to make this growth a sustainable one.]]></description>

      <title>Four Challenges to Incorporating Transportation Demand Management into the Land Development Process</title>
      <link>https://trid.trb.org/View/848617</link>
      <description><![CDATA[There are four primary challenges to incorporating transportation demand management (TDM) into the land development process, based on a review of growth management processes in Florida. These findings may be applicable to many cities outside Florida. The challenges include (a) the idea that TDM is valuable only if it can reduce travel, (b) transportation professionals considering TDM too late in the land development process, (c) the conflict between state and local governments for providing balance between mobility and access, and (d) the use of traffic analysis methods and standards that are geared toward preserving highway level of service (LOS) for motor vehicles. The provision of adequate public facilities for transportation is interpreted by Florida law and administrative code as the achievement of highway LOS standards for motor vehicles and not a broader transportation LOS provided by a combination of modes. Measuring LOS focuses on the delay experienced by motor vehicles on the highway and does not allow the weighing of economic, environmental, public health, and social equity costs and benefits of one mode compared with another. As a result, there is no rational tool to justify a different distribution of limited transportation funds across multiple modes. TDM strategies are positioned poorly, internally to government leaders and partner departments and externally to land developers as a sort of mobility “diet” imposed on the traveling public. This paper offers some ideas on where to direct attention to address these issues.]]></description>

      <title>Minor Amendment to the Tennessee Statewide Multimodal Long Range Transportation Plan</title>
      <link>https://trid.trb.org/View/851468</link>
      <description><![CDATA[The Tennessee Department of Transportation (TDOT) has added three sections to the State Long Range Transportation Plan to address particular issues that have been elevated in importance after recent updates to federal transportation planning requirements. This is considered a “minor amendment” to the Plan because it does not result in any changes to its policies or programs; it simply provides supplemental information to demonstrate how the Plan responds to the issues. Section 1 discusses the possible environmental impacts of implementing the Long Range Plan, as well as potential strategies to mitigate any adverse impacts. The impacts are assessed at a systems level, rather than at the level of individual projects. Section 2 addresses the consistency of the Long Range Plan, and the general statewide planning process, with other adopted plans for managing growth and development. Section 3 explains the state’s planning process for safety and security. (Congress has directed that security be given a higher profile in transportation planning.) Section 3 summarizes the goals and priorities of the state’s Strategic Highway Safety Plan. It also describes the steps that the state has taken to plan for the security of the transportation system. Comments that were received on the draft document have been summarized in Appendix C, along with their disposition.]]></description>

      <title>Documenting Improved Mobility Techniques on SIS and TRIP Facilities</title>
      <link>https://trid.trb.org/View/849584</link>
      <description><![CDATA[The 2005 growth management legislation charged the Florida Department of Transportation (FDOT) with reviewing and providing concurrence on a variety of development types regarding their impacts on the state transportation system.  Of particular concern are roads designated as part of the Strategic Intermodal System (SIS), the Florida Intrastate Highway System (FIHS), and facilities funded through the Transportation Regional Incentive Program (TRIP).  This study was conducted to assist FDOT in carrying out this new legislative mandate.  Specifically, the research objectives are:  clarify the process(es) used in the evaluation of level of service (LOS) regarding transportation site impact analysis for comprehensive plan amendments and developments of regional impact; identify methodology issues and clarify acceptable applications; and define "concurrence" and provide standard guidance regarding review and acceptance of mitigation strategies used to mitigate transportation impacts, particularly on SIS, FIHS, and TRIP facilities for use by FDOT staff and the development community.  This report is comprised of two technical memorandums.  Technical Memorandum I reviews applicable legislation, literature, research projects, and practices regarding FDOT procedures for LOS analysis within the site impact review process.  Technical Memorandum I also identifies issues gathered during a series of interviews held with FDOT and other reviewing agency staff.  This initial stage of research resulted in the development of guiding principles including to champion effective mitigation strategies, to recognize valid mitigation proposals, to provide better certainty of outcomes, and to streamline administration.  Technical Memorandum II includes tools, resources, and guidance to enable transportation partners to respond effectively to growth management issues, to become more proactive, and to maximize use of limited transportation funds.  These transportation partners may include among others, local governments, metropolitan planning organizations, regional planning councils, and the Florida Departments of Transportation and Community Affairs.  It also offers examples of what may be considered acceptable mitigation of transportation impacts to transportation facilities that are part of the SIS, FIHS, or are TRIP-funded, and includes reference to many resource documents to further the users understanding.]]></description>

      <title>Transportation Concurrency: Best Practices Guide</title>
      <link>https://trid.trb.org/View/849586</link>
      <description><![CDATA[This guide presents practical guidance for local transportation concurrency management systems based on a sampling of current and best practices. The guide also provides technical assistance on strategies for addressing the changes to Florida’s concurrency requirements made during the 2005 and 2007 legislative sessions. The guide will also assist local governments in the evaluation and appraisal of local comprehensive plans. Guidance on evaluating the transportation impacts of comprehensive plan amendments is provided in the Appendix. The guide begins in Chapter 1 with an overview of concurrency management in Florida and issues in current practice. Chapter 2 addresses the planning process for concurrency and considerations for establishing level of service standards, applying concurrency alternatives, and developing a concurrency management system. Chapter 3 includes a detailed look at the process for implementing transportation concurrency and the mechanics of a concurrency tracking system. Chapter 4 discusses transportation impact assessment, including the implications of various ways of measuring “impact area” and a suggested traffic impact assessment methodology for concurrency. The chapter concludes with a sample application of the methods presented. Recognizing that transportation concurrency is best accomplished through coordination, Chapter 5 provides strategies for improved multi-jurisdictional coordination in establishing level of service standards and managing concurrency. The chapter also provides guidance on how to address the statutory exemptions from DRI (development of regional impact) requirements allowed under Section 380.06(24), Florida Statutes. The chapter concludes with a series of attachments providing guidance on implementing transportation concurrency in a multi-jurisdictional context. These include a sample methodology for evaluating and mitigating cross jurisdictional impacts, an example application illustrating the concepts discussed in the guide, and two model interlocal agreements for coordination in concurrency management.]]></description>

      <title>Options for Making Concurrency More Multimodal: Phase II Revised</title>
      <link>https://trid.trb.org/View/814655</link>
      <description><![CDATA[Current Washington State Growth Management regulations state that jurisdictions in Growth Management counties must define a Concurrency process that ensures that adequate transportation facilities are present or will be present within three years before construction permits can be issued for new development. The current Concurrency regulations of most cities are based strictly on traffic congestion indices. Yet most city transportation plans assume that a growing segment of travel will occur via transit and pedestrian modes of travel. Research is required to determine practical ways of incorporating transit operations and pedestrian facilities into existing Concurrency systems in Washington jurisdictions. Having multi-modal concurrency systems in place will help reduce congestion in densely populated areas as vehicular trips will be substituted with transit and nonmotorized options.]]></description>
