Abstract: There are differences in each countrys design code for concrete elastic modulus that cause uncertainty in stability analysis of critical buckling load column. This paper investigates the impact of uncertainty on concrete elastic modulus for designing of critical buckling load of building column. The statistical data on materials and applied load being collected in Thailand are used together with an investigation on the uncertainty of the concrete elastic modulus in the design code from 8 countries. Finally the Monte Carlo simulation is used to find out the stability index in term of reliability index. The results show that the uncertainty of the concrete elastic modulus plays an important role in stability analysis and should be considered in the design.

Abstract: This paper presents a novel method to estimate travel time on a road segment using information from other road segments. This method is useful especially in the case that real-time traffic on such road segment is not available. The proposed method is based on the correlation between the road segment itself and the most related road segment. We measure the relation between road segments by dynamic time warping algorithm and apply the K-Nearest-Neighbor algorithm to select the best neighbor segment to estimate the travel time on the target road segment. We found that the best attributes set that can measure the correlation between road sections consists of location of the road segments, day of the week, and current time. The link correlation results can be used as reference data to determine the travel time on the roads that are related.

Abstract: In developed countries, the use of speed humps and bumps have evolved from extensive research and testing which been properly designed and standardized. On the contrary in developing countries, no systematic and scientific studies have been carried out on that environment, especially the study on the effects that the motorcyclists response to the humps and bumps. This study therefore reveals the riders behavior when negotiating their speed to the devices. A case study was conducted in the provincial cities of Thailand where the motorcycle was a major mode of transportation. Six locations with speed humps and bumps were selected. Vehicles passing times were simultaneously recorded at 12 points along each traffic calmed link. From these data, a speed profile for each individual vehicle and for a link could be derived. It is found that speed humps and bumps have critically different impacts on motorcycle rider and passenger car driver. The smaller size speed bumps could effectively control the rider speed but have diverse impacts on the driver. These speed differences could post more safety deficiency to the site. The effect of the device on riders behavior, however, is restricted to a short spatial range (about 20-30 m before and after the device). For the speed humps, the motorcycle speeds are quite varied depending mainly on the road terrain. It is found that the motorcyclists have significant lower acceleration rate on the upgrade terrain when compared to the passenger car. Therefore, it is important to take all these rider characteristics into considerations when design the road humps to control vehicle speed in the developing countries.

Abstract: The objective of this study is to explore the potential for electric motorcycles to support a developing Asian city to be a low carbon society. The study surveyed the attitudes of motorcyclists to determine the proportion of motorcyclists willing to use an electric motorcycle and also estimated the reduction of CO2 emission from the transport sector in Khon Kaen city, Thailand. The approach Bottom-Up2 by road network with the transport demand forecasting model and emission factors by vehicle type were used to calculate CO2 emissions for each road link. 16% of motorcyclists currently using gasoline motorcycles would be willing to use electric motorcycles in the near future. To evaluate CO2 emission reduction, the future condition with introduced electric motorcycles was compared to the future do-nothing condition in the same future year. The evaluation result reveals that the electric motorcycle introduction could reduce 2.4% of CO2 emitted by the transport sector from the future do-nothing condition.

Abstract: Based on a Global Status Report on Road Safety in 2009 [ and in 2013 [, 2007 and 2010 Road Traffic Fatalities (RTFs) data for ASEAN Economic Community (AEC) countries were analyzed and compared, respectively. In this research, both reported and estimated RTFs per 100,000 populations showed relatively low correlation with Gross National Incomes (GNIs) per capita among AEC countries. In contrast, the reported and estimated RTFs per 1,000 vehicles showed reasonably high correlation with both GNIs per capita and number of vehicles per 1,000 populations. The greater the GNIs per capita and/or number of vehicles per 1,000 populations, the lower the reported and estimated RTFs per 1,000 vehicles are. As GNI per capita increases, the proportion of 4-wheeled motor vehicles will rise and the proportion of 2-and 3-wheeled motor vehicles will decline. Therefore, 2-and 3-wheeled motor vehicles were the main contributor to RTFs. The improvement of the adoption and enforcement of national road safety legislation can be generally realized. However, only high income countries (including Singapore and Brunei Darussalam) clearly showed the high performances and only these two countries has adopted and enforced the child-restraint law.

Abstract: The current difficulties of the Italian public budget are likely to lead it to exceed the European limit that sets a deficit not superior to 3% of the GDP. It seems that the council property tax regulations, adopted by Legislative Decree 102/2013 last August, will not be transformed into law. The regulations included the abolition of the council tax (IMU), which currently affects buildings in relation to their land value and not their market value. This study developed in equal parts by the two authors is based on the difference, abnormal in the Italian case, between these two values as well as the social and economic inequalities it generates. It proposes an expeditious model capable of reducing the inequality inherent in the mechanism of tax, ensuring the differentiation of the cadastral value at least with respect to the location of the housing, which - together with the construction characteristics contributes to the diversification of the market value of the property.

Abstract: This paper discuss the thematic of public-private economic negotiation in the realization of urban regeneration programs. The Complex Urban Programs (PUC) represent a generation of planning instruments generally in variation to ordinary instruments of general planning (PRG). These instruments found its legitimacy on new forms of concerted planning, in which the objectives are the effectiveness and efficiency of the public administration and the most important point of view are the quality and transparency of the negotiation between public and private. In these circumstances for the purposes of the feasibility, the arguments of urban planning must necessarily be supported by economic-financial considerations resulting from appraisals of the benefits financial and the new real estate values generated by the decision to promote the program in PRG variant. Particular attention must be paid on the modality for consultation between the public government, the owners and the developers when they comparing on mutual convenience as part of the PUC: the negotiation activities is the time during which the public body can capture a portion of land value generated by the choices of modify the PRG. The aim of this paper is the presentation of the economic negotiation between public and private that the Municipality of Reggio Calabria (Italy), with the technical and scientific support of the university laboratory of economic and appraisal evaluation (LaborEst) has promoted in recent years through two PUC. The two Complex Urban Programs are both located in the south of cities of Reggio Calabria (Italy). The paper describes in particular the model for appraisal of extrastandard charged by private entities participating in the two programs. The model developed by both authors is the result of their common research.

Abstract: As the rapid growth of urbanization, risk of flooding in Asian developing cities has been increasing. Though local agencies have integrated their efforts to develop flood preparedness strategies, deploy early warning systems, and plan for evacuations, the cities are particularly vulnerable. This paper aims at evaluating accessibility to evacuation centers in Asian developing city. Hat Yai city (Thailand) was selected as a case study. In this paper, the accessibility was evaluated by travel time between evacuees houses and evacuation centers. The accessibility time to the public evacuation centers were determined. The sensitivity analysis was performed to investigate the relationship between evacuation demand and total travel time in the network. Finally, traffic conditions on evacuation routes were evaluated.

Abstract: New Car Assessment Program for Southeast Asian countries (ASEAN NCAP) is established with specific objective to elevate motor vehicle safety in the region. In line with United Nations Decade of Action for Global Road Safety 2011-2020 decree, the program is anticipated to influence consumer perception towards opting safer cars. This paper presents the results of ASEAN NCAP Phase II test on eleven popular models via offset frontal crash test, as well as the Adult Occupant Protection (AOP) results. This paper also includes explanation on the criteria for vehicle selection, as well as the direction for ASEAN NCAP to encompass the whole spectrum of occupant protection and vehicle crashworthiness.
