Spot speed study is a crucial tool in traffic engineering as it provides valuable insights into various aspects of traffic flow and helps in making informed decisions. It is used to study the traffic capacity, decide the speed trends, and is also useful in accident studies. Let's discuss each aspect in detail:
1. Studying Traffic Capacity:
Spot speed study helps in determining the traffic capacity of a particular road or section. By measuring the speed of vehicles at various points, engineers can analyze the flow of traffic and identify any bottlenecks or congestion. This information is essential for designing and planning road networks, as it enables engineers to optimize the capacity and performance of the transportation system.
2. Deciding Speed Trends:
Spot speed studies provide data on the speed distribution of vehicles at a given location. This data helps in determining the prevailing speed trends and patterns. By analyzing the speed data, engineers can identify areas where vehicles tend to exceed the speed limit or where the speed is too low, potentially causing traffic disruptions. This information is crucial for making decisions regarding speed limits, implementing traffic calming measures, and improving overall traffic safety.
3. Accident Studies:
Spot speed studies are also useful in accident studies. By analyzing the speed data, engineers can determine if there is a correlation between speed and the occurrence of accidents. They can identify areas where speeding is a significant factor in accidents and implement measures to reduce the likelihood of accidents, such as speed enforcement, traffic calming measures, or changes in road design.
By considering all these aspects, spot speed studies provide comprehensive data that helps traffic engineers make informed decisions regarding traffic capacity, speed trends, and accident prevention. The data obtained from these studies enables them to design and implement effective traffic management strategies, improve road safety, and enhance the overall efficiency of the transportation system.

Spot Speed Study
- Spot speed studies are used to determine the speed distribution of a traffic stream at a specific location. The data gathered in spot speed studies are used to determine vehicle speed percentiles, which are useful in making many speed-related decisions.
Spot speed studies have a number of safety application as follows:
- Speed trends
- Traffic control planning
- Accidental analysis
- Geometric design
- Research studies
Additional Information
Enoscope Method
- It consists of a simple open housing containing a mirror mounted on a tripod at the side of the road in such a way that an observer's line of sight turns through 90°. It is an easy, economical but slow method.
