many other developing cities, Hanoi, the capital city of Vietnam, has also faced many serious problems caused by spontaneous urban development and massive private vehicles As a part of solutions, public transportation systems in Hanoi were paid attention to be invested and developed However, Public transportation meets only partially the travelling demand of urban people Even recent years, the productivity of buses in Hanoi tends to be restrain and even going down in some years Therefore, how to encourage and attract people to use public transportation modes is a more and more urgent topic This research focuses on a key factor which greatly influences the use of transit services This is Walking distance to transit stop and impacts of built environment on this walking distance of riders A Poison Regression model is estimated to analyze the associations of built environment and walking distance to public transit stop using a dataset collected from a questionnaire-based Onboard survey in May 2019 with the geospatial data of BE variables where the dataset contains 609 respondents of the Hanoi Metropolitan Area The results unveiled that: (1) Walking is the majority mode of both bus trips from home to transit stop and from transit stop to final destination; (2) The assumptions about walking distance to public stops (threshold of 400 meters) that planners have given are consistent with the Hanoi context; (3) BE variables may have both positive/ negative impacts on walking distance to public transit stops Finally, some policy recommendations were produced to support for the use of the public transportation modes in Hanoi Keywords: Walking; Walking distance; Built environment; Transit stop ii LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com TABLE OF CONTENTS

INTRODUCTION 1.1 Introduction Over the years, Hanoi has witnessed a rapid development of the urbanization that leads to the increasing demand in travelling, thus to the rapid increase of the transportation means, in particular private vehicles In December 2015, it was reported that the total of private vehicles in Hanoi was 5.8 million units including 376,417 cars and 5.4 million motorbikes (Ngoc, 2016), with the exception of the large number of vehicles from other provinces going in and out the city during the day Such a massive private vehicles population has caused various transportation issues such as road traffic accidents, traffic jam, and air pollution To deal with those problems, Public transportation systems in Hanoi were paid attention to be invested and developed, focusing on buses (only one bus rapid transit (BRT) route is operating and urban railway are under construction in Hanoi) However, public transportation meets only partially the travelling demand of urban people, specifically, public transportation system transports only less than 10 percent demand in Hanoi city (World Bank, 2018) Even recent years, the productivity of buses in Hanoi tends to be restrain and even going down in some years (reduced 0,35 percent in 2015 compared to that of 2014) (Figure 1.1) In particular, the progress of construction and operation for the Mass Rapid Transit system (BRT, urban railway) in Hanoi missed the deadline Therefore, how to encourage and attract people to use public transportation modes is a more and more urgent topic There are various factors that influence the use of public transportation modes, including cost, level of service of the existing system, physical accessibility, spatial access, etc all of which contribute to each person’s motivation and ability to decide to use public transportation This research focuses on walking distance to transit stop because understanding influences on walking distance to transit stops of riders is an important indicator of a transit system’s ability to attract people The public transportation services are widely used when more and more people live and/or work LUAN VAN CHAT LUONG
