Abstract:
To improve the effectiveness of conventional walking-based Transit-Oriented
Development (TOD), introducing Non-Motorized Vehicles (NMV)-based TOD
will be a more efficient alternative since it will increase the spatial extent of the
TOD node’s buffer area. This paper discusses the available Bicycle-based TOD
(BTOD) concept. Based on this concept, the spatial extent of NMV-based TOD
(NTOD) has been calculated. A trip-based survey has been conducted on the
selected regions of Dhaka along the line of MRT 6 regarding who uses NMV
(Rickshaw, Bicycle) and public transport (PT) for his daily commuting. A trip
chain analysis was performed first to capture the trip pattern of daily
commuters. From the trip chain analysis, it has been found that PT-based trip
chains dominated the city’s entire trip chain. Consequently, it has also been
found that walking-only and walking-NVM accessible trips dominate 32% and
23% of the entire PT trip chains. However, based on the findings of trip chain
analysis to calculate the spatial extent by developing regression models, it has
been observed that the access trip length for walking ranges from 1.2-1.4 km,
whereas the access trip length for NVM ranges from 4-4.7 km. In Dhaka, the
catchment area of NTOD can increase the accessibility potentially by spatial
extent expansion of about 70% from the conventional TOD. Therefore, it can be
inferred that NVM will give more spatial accessibility than walking. As a result, a
new window of planning and design strategies will be opened for the planners
and policymakers around TOD station area planning considering NMV. Along
with strategic recommendations, limitations, and future research agendas have
also been discussed in this paper.
