In urban areas, on-street parking is considered a standard feature, despite its advantages and disadvantages. Numerous researchers identified on-street parking as a significant side friction factor and a more pressing issue in developing nations. Especially when it exists near signalized intersections for reasons such as insufficient sight distance, unused green time, decreased capacity at signalized intersections, etc. The various editions of the Highway Capacity Manual (HCM) [HCM. Highway Capacity Manual (2010) (vol. 3) Transportation Research Board] provide the fundamental concepts and techniques for estimating saturation flow (SF), primarily for lane-based homogeneous traffic patterns with different adjustment factors, including for on-street parking. On-street parking was viewed as a categorical variable, either ‘absence’ or ‘presence’ in the vast majority of research conducted worldwide. These techniques are inapplicable in developing nations with heterogeneous, non-lane-based traffic and largely unauthorized on-street parking. Also, the Indian Highway Capacity Manual (Indo-HCM) [Indo-HCM (2017) Indian Highway Capacity Manual (Indo-HCM). In: CSIR-Central Road Research Institute, New Delhi] does not address the effect of on-street parking near signalized intersections. The objective of the present study is to determine the impact of on-street parking near signalized intersections and to identify its influencing zone. The present study collected data from eight signalized intersections, including four base and non-base sections each, located in different regions of India (Delhi, Kerala, and Maharashtra) to examine the variation in traffic composition, driver characteristics, land use, and control conditions. It has been observed that parking maneuver time in Indian conditions is significantly less than that specified by HCM. The primary focus of this study was to analyze the variations in occupied effective width for different types of vehicles, distance of first parked vehicle from the stop line near signalized intersections within a mixed traffic environment. As the distance between the first parked vehicle and the stop line varies, variation in SF at these intersections is also evaluated. When the distance between the first parked vehicle and the stop line exceeds 65 m, there is no observable reduction in SF from base SF. This result aligns with the finding in Indo HCM, which stated that bus stations should not be placed within 75 m of signalized intersections. The findings of this research will aid traffic engineers and planners in assessing the performance of signalized intersections with on-street parking.
