E-bike sharing is considered a new mode of transport that is rapidly developing in China. In order to better understand the factors affecting the intention to use e-bike sharing, this study is based on the theory of planned behavior (TPB) and the technology acceptance model (TAM) and added the variable of policy support. A sample of 441 respondents in a small city in China was collected to analyze residents’ intention on e-bike sharing usage. The results show that the research model can explain well residents’ intention to use shared e-bikes. Perceived ease of use, perceived usefulness, attitude, subjective norms, and perceived behavioral control have direct positive effects on the intention to use shared e-bikes. Among them, the perceived ease of use has the greatest impact on the intention to use shared e-bikes. Moreover, policy support has an indirect positive influence on the intention to use shared e-bikes through partial mediation of attitude and subjective norms. Finally, some strategies to promote e-bike sharing are proposed. This study can provide a better understanding of the acceptance of e-bike sharing and the strategy for promoting e-bike sharing in urban transportation.

Dual formal and informal transport modes have been complementing one another in Bandung City for more than four decades now. The issue appears due to inability of formal transport to provide adequate services to the citizens. However, this accompaniment has brought Bandung City to a quasi-seamless transportation process as both transport modes play their roles as a continuum. Amid insufficient public transportation system in Bandung City, the informal transport modes have properly paired their formal transport counterparts. This study was conducted in Bandung City, Indonesia, by profiling the transportation users, observing the characteristics of both formal and informal transports, and acquiring the relevant secondary information at city and national levels. The study found that within the issue of appropriateness of few modes of informal transport such as becaks and ojeks, they have shown their contribution to the state of quasi-seamless transit process in the city as well as their impacts to reduce the CO2 emission in comparison to formal fossil fuel-based transportation.

All Rapid building growth is one of the top environmental challenge especially in developing nations. Kano metropolis Nigeria is rapidly expanding that calls for in-depth study. The aim of the study is to assess the environmental impacts of buildings growth in Kano metropolis Nigeria towards sustainability. Carbon monoxides CO was sensed with the aid of device Gas Sensor by Crown Cone and water sampled was taken from the existing ponds and analysed in the laboratory considering physiochemical properties of suspended particles, salinity, colour and total hardness. Geographical Information System (GIS) was used for the location maps preparation. Both indoor and outdoor carbon monoxides was sensed and recorded in selected local governments. The Outdoor carbon monoxide records of the sampled local governments areas of Kano Metropolis shows that Tarauni and Kumbotso recorded exactly 012 ppm as the highest records and Tarauni local government area maintain the highest indoor carbon monoxide emission also. Dala and Fagge local governments’ areas depicted 011 ppm as the second highest records with regards to outdoor carbon monoxides emission but Dala, Gwale and Fagge local governments portrayed proportionately equal amount of indoor carbon monoxides emission of 008Ppm. In addition, the results of water analysis reveals that suspended solid contents and the salinity level of Shema Pond being more contaminated with (248 mg/l and 25 mg/l) against Hauran Wanka Pond with (61 mg/l and 20 mg/l). Colour and t. hardness of Hauran Wanka Pond indicates 501 ml/g and 0.16 mg/l) which is higher than Shema Pond with (290 mg/l and 0 mg/l). It is strongly recommended to preserve and conserve both water and air resources in the metropolis for suitability.
