Abstract:
The aim of the research article is not only to propose a solution procedure to solve multi-objective fuzzy stochastic programming problem by using genetic-algorithm-based fuzzy programming method, but also to apply the computational techniques for transportation of the hazardous waste materials. In this article, routing and siting problems for nuclear hazardous waste material are studied and solved. The amount of waste materials generated in the nuclear reactors follows normal distribution. The two considered objective functions are about route selection which includes minimum travel time and minimum number of houses along the way, taking the safety measures into consideration. A multi-objective fuzzy stochastic mathematical model is formulated with the above mentioned objective functions and the route selection as the constraints. The proposed solution procedure is illustrated by a numerical example and a case study.

Abstract:
Automated vehicles represent one of the most active research topic in different engineering fields in the recent years; in particular, transportation systems theory, mathematical modeling, informatics and electronics are all involved in the development of more efficient, accurate and error resilient systems regarding this topic. For modeling purpose, it is useful to introduce a vehicle classification, but the current 6 SAE levels are too detailed, without sharp borders in some case, to be useful for practical applications; thus a 2-class meta-classification has been proposed but it seems too coarse. This paper starts from an analysis of the 6 SAE levels and of sensors developed and used in modern vehicles to establish a relationship between them; this study is useful to devise a new effective 3-class meta-classification useful to transport systems analysis involving automated vehicles.

Abstract:
Traffic flows that achieve transfer of information, transport of goods and passengers at the national level, represent a picture of social and economic population activities in a certain way. Besides that, today there are various standardized parameters that can determine the particularity of the observed region by measuring. In this work assignment, authors have tried to determine if different traffic flow are mutually connected and to what extent, as well as to confirm relationship between different indicators and to point at possible connections between traffic flows and measured indicators. Knowing individual country characteristics and its place in multilateral relations in the world, gives a new frame for defining complex position of the observed region at a wider level.

Abstract:
SAFEPOST is an FP7 European project which was active from April 2012 to July 2016 with the goal of a “reuse and development of Security Knowledge assets for International Postal supply chains”, as its full title explains. SAFEPOST addressed threats to postal security by designing and experimenting a sensor network detection system including gas, radiation, Raman spectroscopy and image-based sensors. In 2015, while SAFEPOST was running, the US Postal Service and IBM suggested the idea of applying sensors to the postal infrastructure components to bring the acquired data to the next supply chain level and optimize efficiency and costs, leading to an Internet of Postal Things.In this paper we provide a perspective view on how the SAFEPOST and Internet of Postal Things approaches can be merged and generalized to supply chains involving not only postal items, but also logistic infrastructures and business processes, in order to design an Internet of Safe Postal+Things.

Abstract:
Background: Whether the international author collaboration and keywords on the topic of transportation management has been changed in the last several decades remains unclear. Along with the big data and API(allocation programming interface) emerged as a field of research with increasing attention being paid to it by scientific researchers and a rapid increase in related literature being reported using the bibliometric analysis, the international author collaboration and keywords should be explored to analyze the current state of research, including publication outputs, in-depth collaboration characteristics and keyword topics of transportation management research.Methods: The authors collected two published papers in Medline library and downloaded their 206 similar articles without duplication since 1977. Various statistical techniques and bibliometric measures were employed, including publication growth analysis; journal distribution; and collaboration network analysis at the author country/area collaboration level. The visualization maps of international author collaboration and burst terms were drawn on Google maps using social network analysis(SNA) and cluster analysis. Gini coefficient(GC) was applied to measure inequality of density indices among clusters.Results: A total of 208 bibliographic records on transportation management were collected. The earliest paper was published in 1977, with the number of papers sharply rising at the inflection point of the year 2014. We found that (1) the most number of papers on the topic of transportation management are from the U.S.( 43,27.04%), Spain(21,13.21%), and China(18, 11.32%); (2) the most linked keywords are organization & administration, analysis, education, and statistics & numerical data, and trends; (3) keyword networks presents lower GC that author collaborations among their respective clusters. Conclusions: The collaboration of international authors on transportation management is not tight and stable. The focus of research topics on transportation management is centralized(Gini=0.48) more than that of author collaboration(Gini=0.33). Our study might provide a potential guide for future research on the topic of transportation management.

Abstract:
Bridge Weigh-in-Motion (B-WIM) is the concept of using measured response on a bridge to calculate the static weights of passing traffic loads as they pass overhead at full highway speed. This paper describes an enhancement to the Moving Force Identification (MFI) algorithm by estimating the response of some DOFs using limited number of measurements in order to increase measurements number (Input). The pseudoinverse of the mode shape matrix has been utilized to approximately calculate the modal response using limited measured response. Then the calculated modal response has been used to estimate more DOFs that are different from the measured one. The proper orthogonal decomposition (POD) technique is employed to determine the governing modes that increase the modal response accuracy. Numerical example for quarter car model passing over simply supported bridge has been established to demonstrate the idea.

Abstract:
In today’s market, managers are being pressurized to deliver the product in a reliable and cost effective manner. The aim of the present work is to model a transportation problem where decision maker has a flexibility to set his own reliability level when he minimizes the overall transportation cost. To achieve this goal, the overall reliability of transportation system is calculated and a mathematical model of transportation problem is formulated. A numerical experiment is also conducted to illustrate the proposed model.

Abstract:
The discounted value of cash flows of assets is negatively related to interest rates (i.e., the discount rate effect). However, economic activity is positively related to interest rates and positively related to the cash flows of assets with tariffs that can be adjusted to manage demand such as adjustable-rate toll roads, but uncorrelated to assets that do not bear demand risk such as non-toll roads (i.e., the cash flow effect). This effect arises in some types of assets from: (i) the positive correlation between economic activity and demand for the infrastructure assets; and (ii) the positive correlation between economic activity and inflation. We find that the cash flow effect dominates the discount rate effect for assets with tariffs that can be adjusted to manage demand and, therefore, the value of these assets increases in periods of economic expansion. Nevertheless, the opposite occurs for assets that do not bear demand risk.

Abstract:
Several studies in the last two decades have investigated the role of built environment on walking. Studies that investigated the role of built environment on walking to transit analyzed the role of various destinations in proximity to the stations. However, few studies have investigated the role of these destinations on walking trip generation at the origin of the trip. Moreover, none of these studies have investigated the role of availability of public services on walking to transit. This study identifies the urban services at the origin of walking trips of the tri-rail commuters in the West Palm, Broward, and Miami-Dade Counties of South Florida. The number of pedestrian users of tri-rail stations and the available urban service were aggregated per Traffic Analysis Zones and analyzed using standard Poisson regression. Findings indicate that availability of urban services such as public education and public recreation have a positive effect on walking to commuter-rail. Implications of this study include the identification and development of Capital Improvement Projects such as libraries to be located in close proximity to schools and colleges. New and proposed train stations should be located in proximity to urban services such as school, colleges, and libraries to encourage pedestrian users.
