operated in Hanoi However, unlike the world, the effect of BRT in Hanoi somehow remains unclear In this context, studies about the impacts of BRT introduction has the necessity, scientific significance and practicality The objective of this study is aim to understand the commuter behavior after BRT introduction in Hanoi, to see if BRT introduction has change the commuter travel behavior (mode choice and walking behavior) and evaluate quantitatively the effects of Hanoi BRT on commuter behavior through data collected by surveying In order to achieve the objective, Difference – In – Difference estimation is chosen to identify and obtain the effectiveness of BRT by comparing the observed changes of BRT commuter (treatment group) and bus commuter (comparison group) before and after BRT introduction The Difference – In – Difference estimation in this study is conducted under regression framework which includes time dummy, group dummy and the interaction term between them Some important findings from the analysis that BRT implementation in Hanoi did have positive impacts on these following aspects: (1) reducing travel time over travel distance of normal bus commuters; and (2) increasing the maximum acceptable walking distance to the station (the willing to walk longer distance for public transportation); and (3) attracting commuters to change their mode choice towards public transport ii LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com TABLE OF CONTENTS ACKNOWLEDGEMENT i ABSTRACT ii TABLE OF CONTENTS iii LIST OF FIGURES v LIST OF TABLES vi LIST OF

that there is no covariance between DBRT and D2018 which is rational and consistent with the explanation because time dummy and group dummy are truly independent variable With all the observed

impacts on encouraging commuters to change their mode choice In the survey data, private vehicle (motorbike, car, others) is marked as 2,3,4 and bus/BRT is marked as Therefore, the negative values of the coefficient will point out the shifting from personal vehicle towards public transport In all comparison – treatment groups, the coefficient of DBRT*D2018 ( ) < which verify BRT’s influence on attracting private vehicle users to switch to public transports Hypothesis is declared to be supported 5.4 Further discussion Normally, different locations possibly bring some differences in various aspect such as people’s income, technical infrastructure, development strategy… which could affect the effect of introducing a new type of public transport In the methodology section, a location dummy was intended to put into the regression formula besides the time dummy and group dummy However, this idea has 48 LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com encountered some obstacles and has not been developed Firstly, the locations difference is likely included in the difference between group (different treatment- comparison group) Secondly, the bus routes are located in the same city, and not quite far from each other They likely will share almost the similar characteristics instead of the differences that different locations would bring Therefore, the effect caused by the different between them is considered to be hard to observe even though it exists However, the correlation between BRT and bus routes about route direction is noticeably different (which could possibly lead to some comments about the location effect):  The route direction of BRT and bus route 01 start from the same station and have its major part parallel with each other They are also located near each other It is reasonable to consider that who use BRT is not using route 01 and vice versa (competitive relations)  BRT and bus route 30 have different route direction but have connection (share a part with each other) People using BRT and bus route 30 could transit between the two routes (support relations)  BRT and bus route 32 have different route direction and no connections It is considered that BRT and bus route 32 have no effect on each other 49 LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com Figure 5.7 Route alignment interaction between BRT and bus routes with BRT route is the red line Bus route 01 is the blue line Bus route 30 is the green line Bus route 32 is the pink line The comparison between the coefficient of each aspect of these routes is carried out using treatment-comparison groups to observe the interaction of BRT with each other bus route (location effect) However, normal coefficient of each aspect has a big gap between each other, which makes it difficult to compare because they are regressed from quantities with different units Maximum acceptable walking distance, travel time over travel distance and mode choice have different units On the other hand, standardized coefficients' advocates note that the coefficients ignore the independent variable's scale of units, which makes 50 LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com comparisons easy Therefore, the standardized coefficient of each aspect are used for comparison This comparison is indicated in Table 7.13 The negative and positive signs, which indicated the trend of aspect (negative is decrease and positive is increase), is exclude in this table Table 5.13 BRT effects comparison between treatment-comparison groups BRT effects on Increase the maximum accepted walking distance BRT & Bus 01 BRT & Bus 30 BRT & Bus 32 0.186 0.193 0.169 0.210 0.179 0.189 0.120 0.053 0.056 Decrease the average travel time/travel distance Attract commuters to change their mode choice According to the table, it is reasonable to consider the interaction between BRT and different bus route has some affects to BRT effects The group with support relation (BRT & Bus 30) shows the strongest BRT effects on increase the maximum accepted walking distance The group with competitive relation (BRT & Bus 01) shows the strongest BRT effects on decrease the average travel time/travel distance and attract commuters to change their mode choice BRT and Bus 32 not have any interaction to each other and therefore BRT effects are average in all aspects considered It could be concluded that the BRT effects on commuter travel behavior are higher with bus route users that have location relation to BRT (which is considerable as a type of location effect) 51 LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com CHAPTER CONCLUSION This study has assessed the impacts of BRT introduction on commuter travel behavior in Hanoi using DID estimation It was found that BRT implementation in Hanoi did have positive impact to commuters The positive impacts are proved and shown through some aspects Firstly, BRT introduction with the advantage of its exclusive bus lane has improved efficiency of public transportation by reducing travel time over travel distance of normal bus commuters It means that with the same travel distance, commuter using BRT will have their travel time smaller than using normal bus Secondly, the advantages that benefits from BRT introduction have increased the walking for transportation of commuter More specifically, it is proved in this study that BRT implementation has the positive influence on increasing the maximum acceptable walking distance to the station (the willing to walk longer distance for public transportation) Finally, the last proved impact of BRT introduction in this thesis is the ability to attract commuters to change the mode choice Besides the normal bus commuter, Hanoi BRT has attracted a number of private vehicle users to switch from their mode towards BRT These impacts on reducing travel time, increasing the walking for transportation and mode choice towards BRT are noticeably related to each other in many ways and through that the rationale when confirming the influence of BRT on commuter travel behavior could be further reinforced Furthermore, the impact of location to Hanoi BRT introduction’s effectiveness is also discussed and partly confirmed when comparing the effect of Hanoi BRT with normal bus routed which have the type of interaction of their routes and BRT route differently Discussing the impact of the location on the BRT effect may be a possible idea for future feasibility studies Additionally, the survey actually also provides good information and data but has not been used completely which possibly use for further feasibility studies For example, the level of service perception data can be used to evaluate the commuter satisfaction with BRT 52 LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com compared to normal bus or other kind of transport In addition, it can be used to rank criteria that affect the satisfaction of BRT users and then compare with others type of transport This research, however, is subject to several limitations The first possible limitation in this study is about the surveying The survey was conducted with commuter of BRT and normal bus routes Although the Socio-Demographic Profile of Sample Respondents show the similarity of the survey respondents to the population of Hanoi city, there still might be a chance that sample does not reflect the general population or appropriate population concerned well enough This results in limitations for the study known as “sample bias” or “selection bias” The next limitation is also about the survey but related to the methodology The treatment and comparison group definition in DID estimation should be “people who live within the chosen radius of BRT/Bus Station” which is normally used However, the information gathered by the survey is not included the address or location of respondents Therefore, their distance to the station are unknown and the regular definition is impracticable Then the definition of the treatment and comparison will be defined by what respondents use (BRT/bus) The final limitation mentioned is few unusual values noted to be different from regular regression conditions of DID estimation under regression framework results This limitation has been discussed and explained carefully in Section 7.2.2 which suggested that these difference come from the DID estimation’s specific assumption and it is acceptable In conclusion, the key findings of this study verify the positive impact of BRT introduction to the commuter travel behavior in
