“…It is found that social, environmental and economic benefits of carpooling service would have significant impact on user's propensity for using this mode. Other researchers have also reported similar benefits of using carpooling as perceived by travelers [3,5]. The findings implicate that the provision of carpooling service would be able to reduce travelers' cost with improved social and environmental conditions of the city as it will help in reducing vehicle miles travelled and energy consumption that are detrimental to the society and environment.…”

“…Seyedabrishami et al [5] believe that with the help of appropriate strategies, it is possible to increase carpooling among travelers and such an increase will help in reducing annual fuel consumption. In the USA and Canada, ridesharing almost represents 8%-11% of the transportation modal share, and the relationship of ridesharing policies with infrastructure development, traffic congestion, energy consumption and related emissions needs to understand well [6].…”

“…People have more potential of carpooling if it is combined with high occupancy vehicle (HOV) lanes [17]. However, Syedabrishami et al [5] state that HOV lanes that reduce travel time for ridesharing may not have high influence on carpooling tendency of travelers. According to Li et al [17], enjoying traveling with others, time saving, helping the environment and society are important factors in carpooling, whereas carpooling partner matching programs, employer carpooling incentives and preferred parking at work are generally the least important factors for travelers in consideration of carpooling.…”

“…The other main motive in designing these statements was to check the influence of such stated lifestyles and attitudes on individual's propensity for carpooling service. All questions in parts 3, 4 and 5 were evaluated using five-point Likert scales, i.e., strongly disagree (1), somewhat disagree (2), neither disagree nor agree (3), somewhat agree (4) and strongly agree (5). Questionnaire items in all parts were designed in such a way that proper responses of current car users and potential car users can be obtained in relation to various aspects of carpooling.…”

Traffic congestion has become a critical issue in developing countries, as it tends to increase social costs in terms of travel cost and time, energy consumption and environmental degradation. With limited resources, reducing travel demand by influencing individuals' travel behavior can be a better long-term solution. To achieve this objective, alternate travel options need to be provided so that people can commute comfortably and economically. This study aims to identify key motives and constraints in the consideration of carpooling policy with the help of stated preference questionnaire survey that was conducted in Lahore City. The designed questionnaire includes respondents' socioeconomic demographics, and intentions and stated preferences on carpooling policy. Factor analysis was conducted on travelers' responses, and a structural model was developed for carpooling. Survey and modeling results reveal that social, environmental and economic benefits, disincentives on car use, preferential parking treatment for carpooling, and comfort and convenience attributes are significant determinants in promoting carpooling. However, people with strong belief in personal privacy, security, freedom in traveling and carpooling service constraints would have less potential to use the carpooling service. In addition, pro-auto and pro-carpooling attitudes, marital status, profession and travel purpose for carpooling are also underlying factors. The findings implicate that to promote carpooling policy it is required to consider appropriate incentives on this service and disincentives on use of private vehicle along with modification of people's attitudes and intentions.

“…On the other hand, to enhance air quality Malaysians have to deduct the main source of air pollution, which is emission from motor vehicles. The remedy to it most probably would be carpool or car sharing with private car users, in which it lessens the fuel consumptions, thus reducing the car emissions (Seyedabrishami et al, 2012). Due to the individual convenience, the hectic lifestyle does not blend in accordance with most Malaysians to practise car-pooling or public transport when traveling to workplaces, schools and other destinations.…”

Considering the causes of environmental degradation are mainly due to anthropogenic activities, this study aims to explore the need of indicating the social-psychological factors among Malaysians in qualifying the level of public environmental awareness and behaviour. A nationwide study has been conducted to examine environmental awareness and behaviour from 13 States and three Federal Territories. The result demonstrated current level of environmental awareness and behaviour among Malaysians, as according to the four categories; water pollution, air pollution, waste management and climate change. 21834/ajqol.v2i5.10 Mei, N.S., et.al., / Asian Journal of Quality of Life, AjQoL, 2(5), Jan. / Mar. 2017 (p.43-53) 44 IntroductionRapid urbanization and determination to pursuit luxury modern lifestyle among the public has caused environmental degradation. Harmful waste generation, climate change, environmental pollution and ecosystem breakdown, to name a few, are the environmental catastrophes that reduce the quality of life. These have been long articulated by a significant number of researchers from various scientific disciplines (Dominick et al., 2012;Asmuni, Khalili & Zain, 2012). The root causes leading to these occurrences is triggered by satisfying human greed through aggressive economic activities without due consideration of environmental consequences.Considering anthropogenic activities are the main causes of environmental degradation, human social psychological factors pertaining to the environment has both direct and indirect implications to quality of life. Despite numerous environmental events and campaigns about anthropogenic pollutions implemented by government and nongovernment institutions that aimed at changing public environmental behaviour, environmental awareness and commitments are less researched and reported. Public awareness and concern towards environmental issues varies at different levels to influence their corresponding environmental behaviour. It should be highlighted that indicating public environmental awareness and behaviour can serve as a useful reference for policy decisions towards a better environment, hence the quality of life.This article discusses the public environmental awareness and behaviour performance in terms of four (4) categories of water pollution, air pollution, waste management, and climate change and examines the performance level of environmental awareness and behaviour among Malaysians as the outcome of a nationwide survey. Literature ReviewKnowing the significance of exploring environmental awareness of Malaysians, it is essential to understand the context of environmental awareness. According to Hassan, Noordin and Sulaiman (2010), environmental awareness has three (3) concepts that include emotional, attitude and practice of sustainability awareness. With the motivating of psychological factors and emotional forces, the intention to conduct the series of environmentally friendly actions is driven. Based on the study accomplished by Altin et al. ...
