Intersections are the points where two or more roads converge at same or different elevations which plays important role in quality of urban transportation network. Signals are provided at intersections for safe movement of large volume of vehicles. For the estimation of performance of intersection behaviour of users plays important role as conflict between users leads to decrease in green phase time which ultimately leads to reduction in capacity of intersection. Saturation flow rate and PCU are important to consider for capacity, design and operation of signalized intersection as India have heterogeneous traffic conditions. Saturation flow rate depends on geometric conditions, flow characteristics, type of movement and traffic behaviour. Violations by users are the problematic traffic behaviours at signalized intersections which lead to reduction in saturation flow rate and capacity and increased delay. The main purpose this study is to develop saturation flow rate model due to users’ violation impact at signalized intersection at Ahmadabad. Data was collected through videography. Multiple Linear regression model of saturation flow rate was formed considering impact of user’s violations. The results showed the significant effect of users’ violations on the saturation flow rate, and the effect of each of the variables was evaluated by the use of proposed model. Result show that On average, one unit increase in the violations by pedestrians at entrance crosswalk (per hour) leads to saturation flow rate decreases by 1.284 unit.On average, one unit increase in the violations by pedestrians at exit crosswalk (per hour) leads to saturation flow decreases by 0.955 unit. Further, On average one unit increase in the traffic light violations by vehicles (per hour) leads to saturation flow decreases by 0.543 unit. Thus it is recommended that Traffic rules for pedestrian movement at intersection should be enforced and they should be fined if not followed.
