“…Rapid rail projects are also intended to reduce various costs to users including vehicle operation, safety, environmental costs and others. There are international examples of rail transportation appraisal work verifying that main benefits of rail transport investments comprise travel time and cost savings (user and agency) and accident reduction [49,93]. By contrast to these research findings, Figure 4 shows that cost savings in travel time, vehicle operation and accidents have a lesser than expected impact on the overall cost-benefit value.…”

“…Other than this, there are also examples of worldwide comparisons of the countries according to their transport project evaluation methodologies. Hayashi and Morisugi [49] carried out such research covering the appraisal methods for transportation projects in the UK, USA, France, Germany and Japan. In common, these studies show that all the subject countries utilise variations of CBA, some of which are complemented by alternative evaluation methodologies in different stages of project evaluations.…”

“…The selection of related indicators for this study is based on common impacts and indicators given by the relevant international literature (see Hayashi and Morisugi [49]; Janic [44]; Odgaard et al [48] among others). In this, four main types of criteria pointing to transport infrastructure provision impacts are specified as: direct changes of land use (development costs/capital investments of rail infrastructure, greenfield land values), changes in development patterns (costs of providing public services), changes in land-use accessibility and transport diversity (road vehicle operation costs, travel time, accident costs, rail operating costs and revenues, area property values (In relation to area property values, there are two key points to highlight: First, the land value-gains accrue to private property owners to a large extent.…”

Developing and Assessing Alternative Land-Use Scenarios from the MOLAND Model: A Scenario-Based Impact Analysis Approach for the Evaluation of Rapid Rail Provisions and Urban Development in the Greater Dublin Region

Abstract:In this study, environmental sustainability implications of planned rail infrastructure investments on the urban form and development in the Greater Dublin Region (GDR) have been analysed incorporating the scenario analysis approach. Various scenarios are developed using the MOLAND Model applications including: A baseline scenario incorporating a continuation of the present dispersed pattern of urban development and an alternative scenario with rail-oriented corridor development, under varying conditions of economic growth. An alternative scenario was also developed for the recessionary development case considering the prolonged recession in the GDR. Further explorations incorporating a Cost-Benefit Analysis (CBA) approach are developed to evaluate the sustainability implications of different land development scenarios in the Dublin Region. This is assisted by focussing on the impacts of rail investments on urban form and development as raised in the international comparative literature. The findings from the CBA assessment positively indicate that containment policies-as represented by the public transport oriented development indicate benefits over the dispersed development case by reducing the negative consequences of sprawl type of developments. In contrast, dispersed development in the baseline scenario indicates costs of continuation of such development patterns exceed the benefits in the long term. This study will contribute to policy support evaluation measures relating to the integration of scenario analysis tool with the CBA approach in assisting the evaluation of new transport infrastructure proposals.

“…This is because it is usual to apply a broad welfare approach-this is very common that many countries evaluate transport policy options, at least options for new infrastructure, using a CBA framework (Hayashi and Morisugi 2000), and in such a framework a broad welfare perspective is taken. If the accessibility effects are included in ex-ante or ex-post policy evaluations, an important issue is how to communicate the outcomes of accessibility measures.…”

Accessibility measures for robustness of the transport system

Accessibility is a key concept in transport and land use policies, and infrastructure-based measures are one important category of accessibility measures. Recently, there has been a significant increase in the attention paid in both academic literature and policy documents to the robustness of the transport system. However, there is not a mature body of literature on the infrastructure-based accessibility measures expressing this concept. This paper proposes a family of accessibility measures to express the robustness of the transport system. These have in common that they express the number of travel options between a given origin and destination, or to conduct activities. The family of measures is conceptualized by using the multi-state supernetwork approach. With respect to the travel options, we discuss (1) the overlap of travel routes, and (2) the choices of travel modes (e.g. car versus train; multimodal). With respect to the activities, we discuss (1) the choice of OD pairs as opposed to activity-travel patterns, and (2) fixed versus flexible activity locations and fixed versus flexible order of activities. We illustrate the travel options and robustness in a multi-modal transport system between the city centers of the HagueRotterdam-Dordrecht corridor (The Netherlands).

Abstract. Reconstruction of traffic accidents has been so crucial scientific process in order to make impartial and judicious decisions. This study focuses on impact speed prediction of accident sufferers just before the collision in a comprehensive scientific way by using an accident reconstruction software called "vCrash" and Function Fitting Neural Network (FITNET) artificial intelligence method (predictor) in case of absence of skid marks or other clues about calculating impact speeds. A sample real world accident was simulated on the software several times by changing collision speeds to form different deformation on the collision regions of the vehicles in every simulation. Every single deformation amount corresponding to each impact velocity was recorded and used as teaching data for FITNET prediction model. Using 10-fold cross validation, mean squared error (MSE) and multiple correlation coefficients (R) were observed to exhibit performance of the prediction model. The model performed high R (close to 1) and acceptable MSE values. This method aims that, in a probable similar accident scene in future, it will be possible to analyze the impact speeds just by entering average deformation amounts into an application on a portable device at the accident scene without requirement of expensive reconstruction tools and it will be a guide for analysis of other accident types.
