travel mode in urban transport system, it is called as the technology taxi service in Vietnam Ride-hailing is the act of requesting a ride from a private passenger vehicle by an app on a smartphone RHS has appeared in Vietnam from 2014, however, it has spread rapidly and affect significantly to Vietnam transport market and travel habit of people Until now, there has been still no completed regulation for the operation of RHS in Vietnam RHS has caused big controversy with the domestic taxi industry, traditional taxi companies claim that RHS is no different from taxis, and that ride-hailing companies (RHCs) should be held to the same operating requirements and regulations as taxi companies, including licensing, fare regulation, and vehicle and driver safety standards in order to maintain an equal and fair playing field The research has also evaluated qualitatively impacts of RHS on local people The results show that people usually use Grab for picking up/sending off their children Some people use Grab to replace their private vehicle to go to work or use it as a paratransit mode After examining the dynamic characteristic of the RHS car, some interesting findings have been revealed The fluctuation of the price of Grab depends on the demand of the market When the demand is high, the price of the trip will high and vice versa The great fluctuation of price frequently happens at the morning peak – hour (6h-9h) on weekdays when people have a high demand for going to work On the weekend, the price frequently fluctuates widely in the afternoon (16h30-19h), in the evening (19h-22h) and at night (22h-23h) when people have a high demand for leisure purpose and going back their home The waiting time for a RHS car does not only depend on the number of the available car around but also depends on the distance between the vehicle and the customer A potential assumption also has been proposed that the algorithm of Grab app automatically raises prices to balance between demand and supply because when bad conditions happen   LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com   CHAPTER INTRODUCTION Ride-hailing also is known as technology taxi in Vietnam – is the act of requesting a ride from a private passenger vehicle by an app on a smartphone This type of system is built, managed, and operated by ride-hailing companies (RHCs), Grab (Malaysia), Uber (United States of American), or Gojek (Indonesia) are some well-known RHCs in South East Asia countries area These RHCs serve as the broker between the customer who has ride demand and the driver who possesses and operates his/her own private vehicle After launch, Ride-hailing service (RHS) has immediately redefined the individual public transport industry (taxi or motorcycle-taxi in some South East Asia countries such as Vietnam, Indonesia, Thailand, and Cambodia) with its user-friendly platform, which includes extra convenience, variety payment method, completed door-to-door service, maximal reduced waiting time RHS has appeared in Vietnam transport market in 2014 with RHCs – Uber and Grab Until 4/2018, Uber sold the whole market share for Grab, stopped providing all services of Uber in Vietnam After Uber was taken over, Grab has occupied a large share of the passenger transport market Within years, Grab almost has dominated the individual public transport market in Vietnam, it has supplied service to a majority of metropolitan regions spanning throughout 36 provinces/cities across the country with 175.000 partners (drivers), has become a important portion of urban transport and affect significantly to operation of other types of transport business, especially type of traditional taxi business as well as travel behavior of people According to Vietnam Parliament Television, by the end of 2017, in Hanoi and Ho Chi Minh City, the number of traditional taxi car is only 23.000, reduced 8000 vehicles compared with transportation planning, meanwhile number of Grab car, from vehicles, increased up to 37000 vehicles The frequency of riding traditional taxi also goes down, 61% of users confirmed that they used   LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com   traditional taxi service less frequently than a year ago (according to the survey of Asia Plus Inc in July 2017) Figure Traditional taxi usage change in last 12 month (Source: Asia Plus Inc on July, 2017) Currently, there is still no completed regulation for the operation of RHS in Vietnam Besides that, RHS also has been causing the big controversy among stakeholders regarding regulatory statutes imposed on its operation The purpose of this study is to understand the history of introducing and the operation of RHS in Vietnam market as well as the reason of controversy based on the review of related websites, review of related laws, and statement of stakeholders about RHS Besides that, a group discussion is carried out with Grab’s user to evaluate qualitatively impacts of RHS on local people Finally, the research will evaluate the dynamic movements of ride-hailing vehicles relied on data of the ridehailing app (RHA) on Information & Communication Technology (ICT) devices – the smartphone Based on the background, objectives presented before, the research question this study pursues to answer is: What is the current problem of ride-hailing service? This thesis consists of chapters This chapter focuses on the background, problems statement as well as the main objectives of this research The following chapters are written as follows:   LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com   Chapter reviews previous researches in the literature to understand the research approach and how to find problems, thereby clarifying the research objectives in accordance with current studies Chapter summarize the history of introducing RHS system into Vietnam; analyze the legal mechanism relating RHS; find out operation of Grab in Vietnam transport market as well as reaction among stakeholders regarding its operation, thereby clarifying reasons of controversy around this type of service Chapter analyze the impacts of RHS on local people through group discussion; describe procedures to collect data by Grab app on the smartphone, thereby determining the dynamic movements mechanism of the ride-hailing vehicle Chapter concludes the discussion and identify current problems which may have on RHS, thereby proposing appropriate policies       LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com   The independent-samples T

which the customer must wait for a car is about minutes, the waiting time in zone is about 10.5 minutes In zone 3, the distance between GrabCar and the location of the customer is quite far, while the distance in zone is much shorter than Therefore, the waiting time 51   LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com   does not only depend on availability, but also depends on the

the waiting time not to be too long                   53   LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com   CHAPTER DISCUSSION AND CONCLUSION Ride-hailing service is a new travel mode in urban transport system in Vietnam However, it has spread rapidly and affect significantly to Vietnam transport market, especially the traditional taxi The appearance of RHS has redefined the taxi industry, Grab has transported tens of millions of passengers while the Government has not lost money to finance for development of this type of service, because it uses socialization source The relationship between Grab and the car driver is a partnership, it is not the relationship between boss and employee Grab does not possess and manage any car The success of RHS in transport market has implied that RHS conforms to the trend of the consumer in the technology era, as well as, indicated that some current business conditions of the traditional taxi service have been too old, too complicated and need to be removed Ride-hailing service also has impacted significantly on the travel habit of local people After the launch of Grab, it make accompanying trips of parents with their children are less than before, people usually use Grab for sending off/picking up their children due to its outstanding features such as tracking journey on the app, cashless payment method, knowing price in advance, knowing car driver information Some people have used Grab replace the private vehicle to go to work because they prefer to be driven by someone rather than driving by themselves and the cheap expense People also have used it as a paratransit vehicle to take them to the bus/BRT station From here, people will use bus, BRT to come to their destination In this case, RHS has encouraged people using the public transportation vehicle The fluctuation of the price of Grab depends on the demand of the market When the demand is high, the price of the trip will high and vice versa The great fluctuation of price frequently happens at the morning peak – hour (6h-9h) on weekdays when people have a high demand for going to work On the weekend, the price frequently fluctuates widely in the afternoon (16h30-19h), in the evening 54   LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com   (19h-22h) and at night (22h-23h) when people have a high demand for leisure purpose and going back their home The research has shown that the waiting time for a GrabCar does not only depend on the number of the available car around but also depends on the distance between the vehicle and the customer Finding for the reason of the surge pricing at the bad conditions such as the peak-hour, the research proved that, at the peak-hour, the waiting time always be very short (about 2-4 minutes) Therefore, a potential assumption is given that the algorithm of Grab app automatically raises prices to balance between demand and supply because when bad conditions happen, demand for using GrabCar is higher, maybe demand will be greater than supply, and waiting time become longer If the demand and the supply are balanced, the short waiting time always be ensured From all findings of this research, Grab is supplying an extremely useful RHS to the customer, has efficiently addressed the inadequacies of the current urban transportation system Besides that, the launch of Grab in Vietnam has forced the traditional taxi to change their business strategy, offer a better quality service to customer Grab also contribute to encouraging people using the public transportation vehicle and decreasing demand for using the private vehicle The fluctuation of price over time or the surge pricing does not affect negatively to the transport market and local people because Grab is not an only RHS supplier in the Vietnam market Besides the traditional taxi, there are also other RHS suppliers such as Be, GoViet, Fast-Go, etc People have many other options for their trip if the surge pricing happens, Grab cannot manipulate the Vietnam transport market However, there have been still no regulations for the operation of Grab or RHS in Vietnam, therefore building an appropriate legal mechanism for its operation is an urgent mission at now to manage and control efficiently this new type of service     55   LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com   REFERENCES
