The purpose of this project was to provide transportation agencies with strategies and resources to meet their needs for attracting, recruiting, and retaining transportation system operations and management (SOM) staff. The research described herein considers the potential supply and demand for SOM skills and staffing; the actions transportation agencies may take to attract, recruit, develop, and retain skilled staff with SOM capabilities; and the tools that are available or may be developed to assist agencies in attracting and recruiting skilled staff in this area. SOM draws on the knowledge of many disciplines including, for example, traffic engineering, intelligent transportation systems, maintenance, emergency response, traffic operations, traffic safety, incident management, performance measurement, and system planning applied in a comprehensive approach to increase the efficiency and safety of the transportation system. SOM encompasses interactions among transportation modes and between the transportation system and other functions such as emergency management, public safety, and outreach. In this report, we provide information regarding the methodology, results, recommended action plans, and potential future research directions in relation to this project.

TRB's National Cooperative Highway Research Program (NCHRP) Research Results Digest 349: Evaluation of Existing Roadside Safety Hardware Using Manual for Assessing Safety Hardware (MASH) Criteria explores the safety performance of widely used non-proprietary roadside safety features by using MASH. Examples of features evaluated include longitudinal barriers (excluding bridge railings), terminals and crash cushions, transitions, and breakaway supports. The complete report on the project that developed NCHRP RRD 349 was published as NCHRP Web-Only Document 157.

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 352: Value Engineering Applications in Transportation examines the current value engineering (VE) practices of highway transportation agencies in the United States and Canada. Value engineering (VE) is the systematic review of a project, product, or process to improve performance, quality, and/or life-cycle cost by an independent multidisciplinary team of specialists. The report identifies the reported best practices, key strengths, and challenges of current VE study processes and agency programs, and offers guidance on applying and improving the effectiveness of VE in projects and programs.

Geography in America at the Dawn of the 21st Century surveys American geographers' current research in their specialty areas and tracks trends and innovations in the many subfields of geography. As such, it is both a 'state of the discipline' assessment and a topical reference. It includes an introduction by the editors and 47 chapters, each on a specific specialty. The authors of each chapter were chosen by their specialty group of the American Association of Geographers (AAG). Based on a process of review and revision, the chapters in this volume have become truly representative of the recent scholarship of American geographers. While it focuses on work since 1990, it additionally includes related prior work and work by non-American geographers. The initial Geography in America was published in 1989 and has become a benchmark reference of American geographical research during the 1980s. This latest volume is completely new and features a preface written by the eminent geographer, Gilbert White.
