Analysis Study of Current Transportation Status in Vietnam's sustainability Article Analysis Study of Current Transportation Status in Vietnam’s Urban Traffic and the Transition to Electric Two-Wheelers Mobility Duc Nguyen Huu * and Van Nguyen Ngoc Faculty of Energy Technology and Faculty of Electrical Engineering, Electric Power University, Hanoi 100000, Vietnam; [email protected] * Correspondence: [email protected]; Tel.: +84-90-1008-555 Abstract: In Vietnam’s major urban areas, private motorcycles are the main means of transportation that are suitable for socio-economic conditions, current transport infrastructure, and people’s habits. However, in recent years, the negative effects of a large number and high density of motorcycles in urban areas such as traffic congestion and noise and air pollution have resulted in a gradual change in the public’s opinion of private vehicle adoption, especially motorcycles. The public has also urged the authorities to issue policies of limiting or curving the growth in the number of private vehicles powered by fossil fuels in big cities. However, in order to achieve the goal, other alternative means of transport should be proposed to encourage people to move to a more sustainable and eco-friendly form of mobility. The alternatives also should be consistent with the average income level as well as social characteristics. In recent years, along with the development of a highly connected public transport network, efficient and less-polluting vehicles including electric two-wheelers have been emerging, thriving, and drawing more attraction from Vietnamese people and policy makers. The Citation: Huu, D.N.; Ngoc, V.N. spread in the number of electric two-wheelers in Vietnam’s major cities may be a sign of the transition Analysis Study of Current to a more sustainable and less-polluting means of transport as an alternative to gasoline-powered Transportation Status in Vietnam’s motorcycles.

However, a large number and high density of private fossil fuel vehicles, of which motorcycles make up over 90%, put high pressure on traffic infrastructure, triggering traffic congestion as well as air and noise pollution in urban areas. In recent years, with a young population structure (the median age in Vietnam is 32.5 years [5] and the population aged 15–24 accounts for 70% [6]) and improving average income per capita (Vietnam GNI per capita for 2019 was 2590 USD [7]), there has been an emergence of the more comfortable, safer, and/or greener means of transport. A significant change in the private car consumption in Vietnam has been witnessed recently. However, the expensive purchase price, tax, fees, and high operation costs are hindering the accessibility of this vehicle type. In addition, traffic congestion, lack of car parking, as well as poor urban transport infrastructure (land fund reserved for transportation is only about 7.5–9.75%) are also barriers to private car adoption. Another notable transition also could be seen in the gradually increasing penetration of electric vehicles, especially electric bikes and electric motorcycles (hereafter referred to as electric two-wheelers or E2Ws), in Vietnam. With the current high rate of motorcycle ownership, the transition from gasoline-powered motorcycles to E2Ws is promising. E2Ws maintain the remarkable advantages that made motorcycles popular while adding other prominent advantages such as zero tailpipe emissions, better efficiency than internal combustion engine (ICE) vehicles, large potential for greenhouse gas (GHG) emissions reduction when coupled with a low-carbon electricity sector, less dependence on fossil fuel import, noise reduction, and provision of ancillary services to power systems [8]. Generally, the introduction of these greener means of transport would be a promising and sustainable solution to mitigating negative impacts of fossil fuel vehicles in urban traffic, and E2Ws could be seen as an alternative solution to replacing gasoline-powered motorcycles in Vietnam. However, although having high potential as well as a continuing growing market share, the deployment of these means of transport is still in the initial phase. In the scope of the literature, there has not been any comprehensively published research addressing the recent personal mobility evolution in Vietnam’s urban areas, especially the transition from fossil fuel motorcycles to E2Ws. Additionally, there are limited studies to assess the advantages and disadvantages of E2Ws in Vietnam as well as the trend of widespread usage of E2Ws in near future. Moreover, the lack of support policies of the government, guidelines on the infrastructure, people’s awareness, investment, and research on E2Ws in Vietnam are the main barriers. Hence, several essential questions for sustainable and successful development of E2Ws in Vietnam are raised as follows: (1) Whether the urban transportation characteristics of Vietnam are suitable or not for the development of E2Ws. (2) Analysis of benefits of E2Ws on: users, society in terms of environment, economics, health. (3) What is the trend of E2W employment in the medium and long-term in Vietnam? (4) What is key difficulty in deploying E2Ws in urban areas in Vietnam? (5) What solutions are needed in order to develop E2Ws suitable for specific conditions of Vietnam as a developing country? In this paper, the authors conduct data acquisition and carefully study all signs and indicators of EV penetration and urban transport evolution in Vietnam. Hence, this paper is the first work assessing all aspects of the transition. The study also lays a foundation and is a good reference for policy makers as well as enterprises to encourage the development of EVs in Vietnam as an economic and sustainable transport solution. This study also provides a reference lesson to other developing countries with similar socio-economic conditions. It therefore makes a great contribution to the sustainable development of Vietnam in the transportation area and energy sector. Our study could be a useful reference for policy makers, people, researchers, and technology companies in this field. Sustainability 2021, 13, 5577 3 of 27 The remaining paper is organized as follows: Section2 introduces the current trans- portation status in Vietnam’s urban areas. Section3 mentions the adverse effects of the overwhelming gasoline power motorcycles in urban traffic such as noise and air pollution, which urge the transition to electric two-wheeler mobility. In the last section, several recommendations for sustainable development of E2Ws in Vietnam are proposed and discussed carefully. 2. Current Transportation Status in Vietnam’s Urban Areas 2.1.

    TO: All Rider Education Recognition Program (RERP) Sponsors, Administrators and Motorcyclist Safety Training Community Members FROM: Motorcycle Safety Foundation (MSF) DATE: May 1, 2020 RE: MSF Interim Recommendations for MSF Basic RiderCourse and 3-Wheel Basic RiderCourse Training, Level II Classroom This is an update to MSF’s previous March 12 & March 17 guidance memos regarding motorcyclist safety training during the COVID-19 emergency. MSF’s ultimate goal is, and will always be, the safety and well-being of motorcyclists. During the COVID-19 emergency, that has meant protecting RiderCourse students and RiderCoaches by recommending the suspension of motorcycle rider safety training. MSF continues to recommend a suspension of motorcyclist safety training activities. We are extending our “no training” recommendation through May 15, 2020. By staying home a while longer, we are following best available guidance, and supporting the life-saving work of medical responders across the country. At the same time, we are looking ahead. When the time is right to resume training activities, we recognize that it will not suddenly become “business as usual.” Things will be different, and will remain that way for some time. Different parts of the country will be ready at different times. As of the end of April, MSF is aware of ongoing training activities in a small number of states. In response to requests from programs that have chosen to proceed with in-person rider training and education, MSF has developed the attached recommendations for interim MSF Basic RiderCourse and MSF 3-Wheel Basic RiderCourse training. For training sites and sponsors that elect to continue or resume training, RERP and curriculum standards are unchanged.

    Motorcycle Safety The Colorado Department of Transportation November 2006 Facts from NHTSA Motorcycles are more likely to be involved in a fatal collision with a fixed object than are other vehicles Helmets are estimated to be 29% effective in preventing fatal injuries and 67% effective in preventing brain injuries While 20% of passenger vehicle crashes result in injury or death, an astounding 80% of motorcycle crashes result in injury or death Facts from NHTSA Motorcyclist fatalities have increased each year since reaching an historic low of 2,116 fatalities in 1997. In 2001, 3,181 motorcyclists were killed, an increase of over 50% between 1997 and 2001. Without this increase, overall highway fatalities would have experienced a marked reduction of about 2.5% over this same time period.

THAI** · Kum Fai YUEN*** Contents I. Introduction IV. Current Status of Logistics in Vietnam II. Literature Review V. Conclusion III. Methodology Abstract The purpose of this research is to present and analyse the current situation regarding the capability of the national logistics system in Vietnam. A national assessment framework for macro-logistics is utilised in combination with semi-structured interviews of key Vietnamese stakeholders to reflect on the current situation in the country. There are still numerous shortcomings in the Vietnamese logistics system. These shortcomings are not purely infrastructure based but also from a regulatory and commercial perspective. The presented national logistics system assessment framework can be replicated in other countries or regions when assessing national logistics capability. The findings can help foreign investors, international logistics providers wanting to provide their services in Vietnam to understand the logistics context within the country. These findings are also helpful for policy makers in Vietnam on how to improve their national logistics system. This study proposes a template to assess national logistics systems and provides an in-depth understanding of logistics in Vietnam, a country that has not been much studied in the literature.

The study aimed to quantify the association between usage of motorcycle clothing and injury in crashes. Methods: Cross-sectional analytic study. Crashed motorcyclists (n=212, 71% of identified eligible cases) were recruited through hospitals and motorcycle repair services. Data was obtained through structured face-to-face interviews. The main outcome was hospitalization and motorcycle crash-related injury. Poisson regression was used to estimate relative risk (RR) and 95% confidence intervals for injury adjusting for potential confounders. Results: Motorcyclists were significantly less likely to be admitted to hospital if they crashed wearing motorcycle jackets (RR=0.79, 95% CI: 0.69-0.91), pants (RR=0.49, 95% CI: 0.25-0.94), or gloves (RR=0.41, 95% CI: 0.26-0.66). When garments included fitted body armour there was a significantly reduced risk of injury to the upper body (RR=0.77, 95% CI: 0.66-0.89), hands and wrists (RR=0.55, 95% CI: 0.38-0.81), legs (RR = 0.60, 95% CI: 0.40-0.90), feet and ankles (RR=0.54, 95% CI: 0.35-0.83).
