Abstract:
Foot over bridges are accompanied with escalators now in Dhaka city. Several projects have been
implemented at present and various such projects will be in the pipeline of the implementation. Our study
tries to identify the performance evaluation of existing escalator foot over bridge. We did our study in two
phases. Firstly, we did the field survey on how many road users were using foot over bridge on particular
sites. The sites are—escalator foot over bridge at Kakoli, Banani and another one is at Airport road just
opposite side of the Airport in Dhaka. The other survey was performed through question form taking
opinion from public. There are total 298 responses which had been collected through google form. The
demographic feature and the attributes data were collected. There were total 13 attributes, which were
ranked strongly disagree to strongly agree and converted into numerical scale 1 to 5. The dataset were
modeled using feed forward neural network (FFNN), which a widely used class of neural network
developed based on biological thinking. The dependent variable of the study was overall condition of the
foot over bridge. The model has 58.5% accuracy in training and 60.4% accuracy in testing. The most
important attribute obtain was congestion and hawker. The concern authority should take care on these
two issues. Most respondents complain on congestion and hawker problems. Government should take
necessary step to eradicate hawker from foot over bridge. More pedestrian foot over bridges are required
so that demand become less than capacity. Hence, the foot over bridges may not become over crowded.
The field survey shows that people are very interested to use escalator foot over bridge. However,
considering budget constrain careful feasibility study need to done, before planning escalator foot over
bridge in a locality. This study can be extended for other areas and localities and other sorts of pedestrian
facility study.
