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
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.

Introduction:
Spot speed study is a technique used in traffic engineering to collect data on the speeds of individual vehicles at a specific location and time. It helps in understanding various aspects of traffic flow and is beneficial in several areas of traffic engineering.
Explanation:
The correct answer is option 'D', which states that spot speed study is useful in all of the following aspects of traffic engineering:
a) To study the traffic capacity
b) To decide the speed trends
c) To use in accident studies
1. To study the traffic capacity:
Spot speed study provides valuable data on the speeds of vehicles passing through a specific location. By analyzing this data, traffic engineers can determine the capacity of a roadway or a specific lane. The spot speed data can be used to calculate the flow rate and the density of vehicles, which are crucial parameters in traffic capacity analysis.
2. To decide the speed trends:
Spot speed study helps in determining the prevailing speeds of vehicles at a particular location. This data can be used to identify the speed trends, such as average speed, 85th percentile speed, and maximum speed. These trends help in understanding the behavior of drivers and can be used in setting speed limits, designing roadways, and implementing traffic control measures.
3. To use in accident studies:
Spot speed data is also useful in accident studies. By analyzing the speeds of vehicles involved in accidents, traffic engineers can identify potential factors contributing to accidents, such as excessive speed or speed differentials. This information can be used to improve road safety by implementing appropriate countermeasures, such as speed limit enforcement or road design modifications.
Conclusion:
Spot speed study is a valuable tool in traffic engineering as it provides essential data on vehicle speeds. This data can be utilized to study traffic capacity, determine speed trends, and analyze accidents. By understanding these aspects, traffic engineers can make informed decisions to improve road safety and optimize traffic flow.
