For Considering low vehicle speed in urban areas, there have been 465 fatal crashes collectively in the urban municipality of Mashhad city all of which involved bicycles or motorcycles, from spring 2010 until spring 2013. This accentuates the necessity to allocate funding to decrease the number of crashes, especially, so that number of crashes decreases significantly in the vicinity of bicycle lanes. Accordingly, to allot an economical budget to construct bicycle lanes seems logical. Additionally, it is likely to increase the share of bicycle travels contributing toward improvement in other issues such as pollution, congestion, and public health as well. As goal of this paper, introducing a network suitability function for varying budgets, prioritized potential links for bicycle lanes are specified. A model that incorporated integer programming was proposed so that potential links could be ranked considering various budgets using sensitivity analyses. In other words, variables are ranked based on indices to enable the decision makers to address critical links before others. In addition, insensitivity of simplified objective function to relative importance coefficient of annual data can be implied as existence of a meaningful correlation between crashes per year in potential links; lack of modification in the network is likely to be the cause of this correlation. Moreover, links that are planned by Mashhad Transportation Studies Center experts are in agreement with final results of this paper.
