Denpasar city is the capital of Bali Province and has been developed into a metropolitan city. There has been an agglomeration of four regencies, namely Denpasar, Badung, Gianyar and Tabanan forming a Metropolitan Sarbagita area with a population close to 2 million inhabitants. With heightened population and activity, travel patterns are increasing and scattered. The development of land use in the Sarbagita Metropolitan area occurred rapidly and was not properly anticipated by the provision of adequate infrastructure. This study aims to examine the patterns of movement that occurs and projections for future conditions as a basis to develop a more sustainable transportation infrastructure. The data used are the origin-destination of people and goods, and statistical population data. The prediction method uses four-stages modeling with the help of Visum software and was validated based on the average daily traffic (ADT) data. The results of the study indicate that traffic accumulation occurs on most arterial and collector roads especially around Denpasar with a degree of saturation exceeding 1. To anticipate future population and increased activities, developing a mass public transport system, multi-mode system, ICT system, and limiting the ownership and use of private motor vehicles is necessary.

The Relationship

This study aims at investigating the relationship between spiritual intelligence and organizational commitment in male teachers of elementary schools in Quchan in the 2013-2014 school years. This is an applied research. Since the researcher sought to study the relationship between the two components, this is correlation research. Considering the variables studied, statistical population was all male teachers in grades three and four at elementary school in Quchan in the 2013-2014 school years. Total number of teachers obtained from Quchan Department of Education was 98 and due to the small size of study population, sampling wasn't performed and the sample was considered equal to the population. Data collection tools were Meyer and Allen's organizational commitment questionnaire and Abdullah Zadeh's spiritual intelligence questionnaire. Having completed the questionnaires, the researcher used mean central statistical indicators and standard deviation dispersion measures and variance for data analysis in descriptive statistics level and in inferential statistics level, they used multivariate linear regression statistic method.The results showed that there was not a significant correlation between total spiritual intelligence and total organizational commitment. There was not also a significant correlation between spiritual intelligence and its components with continuance and normative commitments. However, there was a significant correlation between spiritual intelligence and its components with affective commitment.The findings indicated that spiritual intelligence has been effective in maintaining and improving organizational commitment and it should be tried to improve spirituality and spiritual intelligence in employees and teachers.

IntroductionTraffic events are one of the five leading causes of mortality in Mexico. Pedestrians are one of the main road users involved in such incidents and have the highest mortality rate, which is regularly analysed in relation to vehicles and pedestrians, but not the built environment. The purpose of this study was to analyse the elements of the road system organisation that influences the mortality rate of pedestrians hit by motor vehicles in the Guadalajara Metropolitan Area.MethodWe designed a case and control study in which the cases were sites where a pedestrian died during 2012. The controls were sites close to where the death occurred, as well as those with road infrastructure characteristics similar to those where the events took place. We obtained the pedestrian data from the death certificates and assessed some of the environmental elements of the road sites. A logistic regression analysis was used to estimate OR; 95% CI.ResultsRoad system factors related with pedestrian mortality in close locations were: the presence of bus stops on intersections in one street or both, and road system features, such as the presence of traffic islands, vehicle flow and pedestrian flow.ConclusionsAccording to the urban network theory and multiple theory, the final elements resulted as risk factors due to a fault in connectivity between the nodes. A temporal analysis of urban features will help urban planners make decisions regarding the safety of pedestrians and other road users.

The Impact

The main goal of this research is to evaluate the relationship between the built environment and public health of citizens in four different buffers of Sanandaj, Kurdistan province, Iran. There is a growing body of evidence that links the neighborhood design to public health and argues that the built environment impacts on the public health of people through the weakening or strengthening of sustainable transportation (walking, cycling, and public transportation) and physical activity. Regular physical activity has a significant impact on the health of individuals, and this can be the best way to cope with several diseases. The statistical population of this study includes people between the age of 18 and 65 years in Sanandaj city. The method used to investigate the normality of dependent variables is the Kolmogorov–Smirnov test; the assessment of the resident’s difference of physical activities is conducted through one-way variance; the impact of the built environment on physical activities is assessed through a multivariate regression test, and the effect of physical activity on the health of the individuals is evaluated through a correlation test. This study, by explaining the characteristics of the built environment in four different buffers, has exhibited that the environment supporting physical activity of pedestrians plays a critical role in increasing the amount of physical activity they engage in.

The Impact

Transportation infrastructure engineers and managers have realized the importance of appropriate performance assessment and its impact on overall infrastructure performance and condition. The need for robust, comprehensive, and informative performance measures requires further research and study. Recently, the Center for Sustainable Transportation Infrastructure at the Transportation Institute of the Virginia Polytechnic Institute and State University proposed a flexible framework to aggregate condition measures for different highway infrastructure assets and to translate the measures into corridor health indicators. Health indicators for one asset are aggregated into an associated asset health rating, and all asset health ratings are combined into a corridor health rating. This paper modifies this framework to develop a robust performance assessment method that can be used to determine the impact of investment decisions on various dimensions of performance at the corridor level. Instead of aggregating health indicators of an asset into one asset health rating, the method proposes aggregating similar health indicators of different assets into the associated corridor health indicators to develop corridor performance measures. The application of the methodology on a segment of Interstate 81 suggests that the modified approach enables consistent monitoring of different health indicators at the corridor level. The corridor indicators are homogeneous (combined from similar health indicators of different assets). The practicality of the approach is illustrated through its application in a resource allocation example. The results show that decision makers can use the framework as a guideline to allocate resources across different highway assets.

Fuzzy Logic Approach

Urban population in India has increased significantly from 62 million in 1951 to 378 million in 2011 in six decades. It is estimated to reach 540 million by the year 2021. This reflects on likely pressure on urban transportation system. The situation necessarily calls plans for balanced personal and public transport system. Mandatory trips bear more importance in this regard owing to their higher share in urban trips. Mode share and their choice behaviour in estimation of such trips play vital role in analysing and boosting sustainable transportation. Logit modelling approach is the conventional method generally adopted for analysing mode choice behaviour, which is based on the principle of random utility maximization derived from econometric theory. However, such models cannot address uncertainity prevailing in the choice decisions. On the contrary, fuzzy logic bypasses the binary crisp derivations of the inputs and accepts multivalued inputs in linguistic expressions, which make possible to resemble the human behaviour closely. Therefore, the attempt here is to develop fuzzy logic based mode choice model for education trips, which constitutes a good share in mandatory trips by covering various income groups of Indian society.

Public Transport System

The Arabian Gulf cities are growing. The gulf cooperation council states (GCCs) are among the richest and most urbanized in the world. As a major focus on sustainable development of cities, sustainable transportation acts to diminish the city’s energy consumption by providing a public transport system that has greater ecological obligation and societal justice. The study’s significance is to figure out the challenges in the sector of public transport in the city of Muscat. The wide spread of mass transportation plays a significant role in reducing the exhaustion of energy. Also, it contributes to make a better living experience.  Provision of sustainable public transport will prevent the increasing number of motor cars and equally accompanied environmental pollution and traffic congestion. The study is based on an in-depth quantitative and qualitative research method to explore the hindrances that are encountered in the way of building sustainable infrastructure of public transport. The findings of the study revealed that public transport system face real challenges in Gulf region, particularly in Muscat. It indicated that for the well-being of Gulf society, the use of public transportation was encouraged and most of the population have their own cars. In addition to it, cultural and social preservations are raised, mainly by the people that act against the operation of public transport system. Due to the substantial effect of clean  and  sustainable transportation  on energy consumption levels, recent years have been marked with a notable trend  towards  sustainable and  low carbon systems, particularly the mass  transportation ones.
