Opis:
Using the notion of isolated urban islands, this paper discusses, from a theoretical point of view, three important but controversial issues related to the measurement of social exclusion in the big cities: (i) the extent to which social exclusion is likely to occur, (ii) accessibility indicators that are sensitive and relevant for the evaluation of social exclusion, and (iii) the geographical scale for evaluation. From an urban island point of view, two important issues have been raised: the distribution of jobs, basic facilities, and services within an urban island and the travels of people between urban islands. Therefore, social exclusion can be determined either by the affordability/acceptability of travel time/cost to access the minimum requirement of facilities/services or the number of facilities/services in reach of the individuals within acceptable/affordable travel time and cost. A person will be at risk of social exclusion if they belong to a minority group as opposed to the majority in the same society. Some levels of social exclusion risk have been proposed. The evaluation should be implemented at the meso-level (urban island). From the view of the urban islands, the issues of transportrelated social exclusion are clearly understood, and measurements of social exclusion should be solved. We feel that a detailed survey/interview is needed for areas at high risk of social exclusion, followed by an evaluation at the micro-level to identify excluded people and the causes for their exclusion. It is expected that this paper will attract researchers to pay more attention to this issue.

Opis:
Urbanization has created continuous growth in transportation demand, leading to serious issues, including infrastructure overload, disrupted traffic flow, and associated vehicular emissions. As a result, resolving these problems has become one of the primary missions of governments worldwide. The optimization of the traffic signal timing system is considered a promising approach to overcoming the negative consequences of increasing vehicle volume. In metropolises, oversaturated intersections, where the traffic density and vehicle exhaust emission levels are significant, have been considered as the priority to target. Several scientists have attempted to design traffic lights with the most appropriate timing. However, the majority of previous studies have not formed a comprehensive evaluation of essential factors, especially regarding the appropriate weighting of vehicle emission parameters. By assessing the all-inclusive relationship of critical elements with an emphasis on vehicle exhaust emissions, a performance index model using a genetic algorithm (GA) is established in this paper, demonstrated by data from a case study in Taiwan.

Opis:
Developing countries are facing sustainability problems in developing rural transport infrastructure; the problems arise from the lack of financial resource and public support. Enhancing community participation promises to resolve these challenges. Demographics has a strong influence on community participation; however, how demographic characteristics interact with community participation has been yet to be focally studied. Dong Nai, a southern province in Vietnam, was selected as the case study owing to its high requirement of rural transport infrastructure. Questionnaires were sent to 438 households. An analysis of data was performed descriptively and with logistic regression. Community participation was recorded as financial, labor, material, and land contribution. Household composition, education, income, and member in household as community leader are among the highest influential factors to community participation. With the importance of community participation, the results of the study benefits both policy makers and local governments in planning, predicting the success of local development programs, and enhancing community participation, which increase the chance of success in rural transport infrastructure.
