The rapid urban growth in developing city increases the requirement of the efficient and sustainable public transportation *** urban growth affects the urban form,which indicates the change in human and urban development *** form affects directly and indirectly access to the public transportation system as an assessment of potential riders and proximity to stops increase transit services ***,access is one of the important aspects for the assessment of transit service *** transportation access can be represented by a coverage area and useful to estimate potential riders of public *** this study,a Geographical Information System(GIS)-based spatial statistical analysis method is used to examine the spatial relationship of different urban form indicators with population or riders of transit service in a coverage area and to ascertain how urban form influences public transportation trips in this coverage *** coverage area is delineated using a GIS-based road/street network distance *** spatial analysis results suggested that urban forms have certain impact on trips in coverage area at both ward level and zone *** statistical analysis implies that significant and positive values of spatial lag coefficient indicate a positive spatial interaction between wards and variable like total coverage area;worker density have shown positive and significant effects on trips of public transportation.

In the present letter, an efficient, clean and one-pot synthesis of 2-substituted benzimidazole and 1,2-disubstituted benzimidazole derivatives has been explored by reacting o-phenylenediamine with aromatic aldehydes using bismuth nitrate as a catalyst in ethanol at ambient temperature. This methodology avails with faster reactions, excellent yield, mild reaction conditions, use of inexpensive and non-toxic catalyst compared to literature reported hitherto.
