Abstract Transportation systems are one of the key components of forest recreation activities, yet they are often overlooked and seldom adequately considered in the planning process. This paper presents a road impact model (RIM) used to analyze transportation networks to determine their impact on recreation opportunities in an area. Four categories of opportunities are considered in this analysis: experiential recreation, physical recreation, transportation network, and aesthetics. The RIM model is demonstrated on a test area utilizing a geographic information system (GIS) to aid in spatial data handling. The case study presents and demonstrates an assessment framework based on simplified interpretations of the four identified opportunity classes. This spatially explicit approach will aid recreation planning through providing information on current recreation opportunities and on potential recreation opportunities driven by changes to the road or trail systems in an area.

Measures Of Effectiveness

The issues associated with incorporating intelligent transportation systems (ITS) strategies into alternatives analysis planning studies such as major investment studies (MIS), which have emerged since the Intermodal Surface Transportation Efficiency Act was passed in 1991, are discussed. The challenges and implications of including ITS in three of the key steps of the MIS process—problem definition, alternative definition, and analysis—are examined. As context for the specific issues addressed, a case study is presented on incorporating ITS into a corridor planning process that is being conducted using Seattle data. Critical to incorporating ITS elements within an MIS process is developing a problem statement, goals and objectives, and measures of effectiveness that are sensitive to ITS and other operational improvements for the corridor or subarea under study. Traditional MIS processes have focused on facility/service improvements and on average conditions and demand. ITS strategies, on the other hand, aim at improving ( a) operations; ( b) response to nonrecurrent conditions; and ( c) providing better information. To be able to address ITS strategies, the analysis approach used in an MIS should be sensitive to these issues. An illustration of how ITS strategies are being incorporated and evaluated in the Seattle (MIS-like) case study concludes the discussion.

This paper proposed an innovative strategy for planning multimodal, integrated, intelligent, and sustainable mobility by applying 3-tiers mobility stations system combine with car sharing and bike sharing, which aims to promoting the accessibility with available transportation systems and enhance the intramodality and utilization of non-motorized transportation modes. Through the case study of the Fürstenfeldbruck city region in Germany, the 3-tiers mobility stations system concept and its planning criteria and indicators were proposed. And mobility service offerings and location selection of stations were analyzed by considering demand and coverage. Subsequently, evaluation methods based on the pre-defined indicators were implemented to the case study. The planning process is target-oriented and based on relevant structural data analysis.

Road Planning

All too often, engineering strategies aimed at improving road safety are reactions to existing problems that occur after a road has been designed and built. Targeting problem locations and developing plans to reduce collisions are vital and have proven to be very successful. Transportation professionals, however, should also take a proactive approach to address road safety before problems emerge. This paper describes an evolving need of how to deal with road safety in a proactive manner. Although a proactive approach should improve the overall safety performance, there is currently a poor understanding of how to proactively plan for road safety. Several logistical and technical obstacles hinder the effective planning for road safety. Each of these obstacles is presented in detail, followed by a description of the opportunity to overcome each obstacle. The paper also includes the results of a case study used to demonstrate the proposed process. A proactive approach to road safety complements traditional, reactive methods currently in use. Significant progress will be realized once safety professionals shift their focus from fixing existing problems to helping plan roads that attempt to be problem free. The net result should be a safer road system.Key words: proactive road safety, safety audits, safety planning, safety evaluation, safety improvements.

The author describes the performed GIS-analysis of the Central Asian transportation systems. The road transportation infrastructure of the whole region and its individual countries (Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan) has been studied. The overview of the factors, influencing the formation of regional transportation systems, including historical, political and natural, has been done. The road network of Central Asian countries has been modeled using GIS network analysis toolset, with spatial data provided by OpenStreetMap. The so-called topological tiers of the network have been identified, showing the uneven provision of the studied area with road transport infrastructure. The proposed research method makes it possible to note a high degree of the road network integration between the countries. The areas with low transport accessibility, as well as autonomous parts of road network have been visualized. The research categorizes the countries’ transport networks configurations types formed under the influence of economic, social, agricultural, climatic and topographical factors.

Transportation is a sector which plays an important role in the process of development of countries around the world. A crucial step in transportation planning process is the measure of the efficiency of transportation systems in order to guarantee the desired service. This paper investigates the relative efficiencies of lines of the main public transportation company Dakar Dem Dikk (DDD)\footnote{\textit{Dem Dikk} meaning \guillemotleft Go-Return\guillemotright} in Dakar (Senegal). The objective is to apply Data Envelopment Analysis (DEA) and bootstrapping approaches in order to identify opportunities for improvement. In this study, we examine technical efficiency for the 24 lines of DDD using Constant Returns to Scale (CRS) and Variable Returns to Scale (VRS) DEA output oriented models. We apply bootstrap approach for bias correction and for confidence intervals creation of our estimates. Finally, we examine the returns to scale characterization of lines. The results establish that there exist possibilities for improvement for the lines and also shown that there are potential for restructure for some lines.

Government agencies and nonprofit organizations have increasingly used spatial data to create equity and opportunity atlases or maps. This paper investigates how such maps have been integrated into planning processes, and if they have been useful in catalyzing engagement on equity issues. We employ a multiple case study approach to assess efforts in five U.S. regions: Atlanta, Denver, Minneapolis–St. Paul, Portland, and Seattle. Our findings show that equity and opportunity mapping have stimulated new conversations, local actions, and regional plans, but many regions are still struggling to adopt policies that could meaningfully shift their landscapes of equity and opportunity.

Risk Of Mortality

Introduction: Externalities from transportation, and in particular exposure to vehicle emissions have been considered a possible cause of several negative health outcomes including mortality. However, the existing findings are too inconsistent to drive a well-founded exposure-response function to be fully exploited to curb the negative impacts of transportation systems on public health. In this study, we investigate the association between exposure to air pollution and mortality. We then evaluate how using different air quality methods may result in detecting different health outcomes. Methods: We conduct an analysis of reviewing a representative sample of main published studies that specifically focused on the association between vehicle air pollution and mortality. Results: Our study finds that vehicle air pollution may increase the risk of mortality through a slightly high association. Most importantly, the risk of overall mortality increases by 5% per 10 µg/m3 increase in NO2 concentration, 2% per unit of traffic intensity on the road, and 7% per unit of distance closer to the road. Conclusion: The findings imply the role of exposure to vehicle emissions in increasing the risk of mortality. The method used to detect the health outcomes can alter the health finding from positive to null or vice versa and even extensively affect the analysis outcomes. The results suggest the need for establishing indicators to benchmark the performance of air quality methods and emphasize the necessity to integrate public health measures into the urban and transportation planning process.

Road Planning

Route planning and development for operational forest harvesting is an important component of the forest management process. The need for an efficient and low-cost transportation network is significant, as it is likely to dictate or impact the profitability of a particular management plan. Approaches for automating or aiding the road planning process are essential. This paper discusses one interpretation of this planning problem and provides a formal mathematical specification of the problem. This research contributes to the further development of analytical methods for addressing operational forest planning and management.

Natural resource managers need up-to-date information about how people interact with public lands and the meanings these places hold for use in planning and decision-making. This case study explains the use of public participatory Geographic Information System (GIS) to generate and analyze spatial patterns of the uses and values people hold for the Browns Canyon National Monument in Colorado. Participants drew on maps and answered questions at both live community meetings and online sessions to develop a series of maps showing detailed responses to different types of resource uses and landscape values. Results can be disaggregated by interaction types, different meaningful values, respondent characteristics, seasonality, or frequency of visit. The study was a test for the Bureau of Land Management and US Forest Service, who jointly manage the monument as they prepare their land management plan. If the information generated is as helpful throughout the entire planning process as initial responses seem, this protocol could become a component of the Bureau’s planning tool kit.
