The primary objective of this study is to examine various types of speeds on hill roads in mixed traffic conditions and critically review NH-7 at various road sections with different geometrical features. This study aims to identify different speeds such as design speed, lower speed, upper speed, median speed, and model speed. Additionally, a speed model is developed using multiple linear regression (MLR) to determine the relationship between vehicle speed and factors that affect vehicle speed. The study investigates the variance, examines the influencing factors, and develops a model for vehicle speed on hill roads in mixed traffic conditions. The data was collected using a videography methodology at four study sites on NH-7 in Srinagar Garhwal, Uttarakhand. The findings indicate that the upper speed limit (85th percentile value) is 50.64 km/h, while NHAI’s recommended speed limit is 40 km/h, which may result in traffic congestion. The speed model developed in this study can be used to establish speed limits, design and evaluate highways, and implement other enforcement measures.
