Assessing Sidewalk Conditions in Dhaka: A Comprehensive Condition Index Analysis for Key Roads

Abstract: The deteriorating condition of sidewalks in Dhaka, Bangladesh, poses significant challenges for pedestrian safety and usability. This study introduces a systematic approach to evaluate sidewalk conditions through a newly developed protocol for calculating the Sidewalk Condition Index (SCI). The methodology involves an extensive literature review, field surveys, videography, and distress assessments across 50 major sidewalk segments in Dhaka. A total of 28 distinct sidewalk-related issues were identified, each assigned a weight for evaluation. The analysis highlights the eight most hazardous areas, leading to the development of a calibrated SCI that categorizes sidewalk conditions from excellent to poor, based on distress severity and frequency. This study provides essential insights for local authorities, aiding in the prioritization of sidewalk maintenance efforts and effective budget allocation. The proposed sidewalk management strategy includes a five-year planning framework focused on the construction, rehabilitation, and long-term maintenance of sidewalks. Moreover, the research emphasizes the need for incorporating universal accessibility and proper drainage systems into sidewalk designs to enhance pedestrian safety and facilitate greater usage, especially by physically impaired individuals. The findings underline the urgency of implementing targeted policies and standardized guidelines for urban infrastructure planning, particularly in rapidly growing megacities like Dhaka. By following the SCI-based prioritization framework, the city can address critical sidewalk issues more systematically, improving overall walkability and reducing pedestrian fatalities. This research offers a practical model for urban planners, providing a replicable framework for enhancing pedestrian infrastructure in Dhaka and other cities facing similar challenges globally.
