This study aims to evaluate the accessibility during earthquake evacuation for movement challenged persons (MCPs), a disable group highly vulnerable to earthquake, and explores their risk perception in the context of megacity Dhaka, Bangladesh. As there is no accessibility measure to determine accessibility of a network of MCPs integrating physical impedance faced by them in their movement, this study has modified Link to Node Ratio calculate the accessibility of MCPs with consideration of physical impedance and applied it determine the accessibility of MCPs to evacuation routes of 13 wards of Dhaka. Study of accessibility of MCPs during evacuation reveals that 6 wards have poor overall accessibilities while 3 wards have relatively satisfactory conditions of overall accessibility and 4 wards have relatively good accessibilities but fall short of satisfactory conditions. The study reveals that MCPs who are more aged and have more severe level of disability perceive accessibilities of evacuation network, indoor floor surface and entrance gate to be lower. Moreover, male and better educated MCPs is found to perceive accessibilities of indoor floor surface and entrance gate to be higher. Age, income, structure, having experienced an earthquake earlier, mass media as a source of information on earthquake training is found to contribute to perceiving higher level of earthquake risk (as a whole). MCPs who have participated in the training program is found to know what they should do in the advent of an earthquake irrespective of being outside or inside of the home. The study reveals lack of accessibility in training centers and lack of distribution of information of training programs as key reasons behind MCPs not participating in the training.
