Abstract
- The systematic handling of highly heterogeneous traffic is a difficult task for traffic engineers. High traffic growth, a lack of proper road traffic management, and lane indiscipline all contribute to vehicle delays, particularly at intersections. Traffic signal delays are a major issue in urban areas. The aim of this study is to analyze delay at four-legged signalized intersections using the HCM delay model equation and validate it using the VISSIM software.
Where is the delay of the vehicle, g is the effective green time (s), C is the cycle length (s), X is the degree of saturation, c is the capacity (PCU/hr) and T is the analysis period (s).
Key Words: Delay, Signalized intersection, Traffic volume, Vissim

1. INTRODUCTION
For collecting the data, four signalized intersections selected where as follows:
Delay is an important variable in signalized intersection performance evaluation. The most significant of these is vehicle delay, which refers to the amount of time a vehicle loses when crossing an intersection. Due to the nondeterministic nature of vehicle arrival and departure processes at intersections, as well as the influence of various variables with uncertainties and ambiguity, especially under heterogeneous traffic circumstances, delay is a parameter that is difficult to measure. For traffic engineers and transportation planners, modelling vehicle delay has been an intriguing topic. Road users are experiencing delays during peak hours due to heavy traffic flow. Excessive traffic flow, insufficient road capacity, a lack of parking areas, poor pedestrian infrastructure, parking of heavy vehicles on main roads, and other factors all contribute to congestion, resulting in delays and excessive queue lengths.
Delay calculated using HCM delay model equation was validated using VISSIM software. VISSIM is a microsimulation model that helps to create the real time road condition.

Video recording technique was used to collect data. Suitable building was selected for placing the camera. Camera were placed at sufficient height so that the signal timing and volume count can be extracted from the recordings.
We have selected four signalized intersections for our study. All the intersections chosen were four legged intersections. Delay was calculated using HCM delay model equation. [1] Figure - 1 : Angamaly KSRTC Junction
