deliberation because it relates to safety, time, comfort, convenience, and economics. Spot speed studies are used to determine the speed distribution of a traffic stream at a certain location. The data assembled in spot speed studies are used to determine vehicle speed percentiles, which are useful in making many speed decisions. The intention of spot speed studies are to record speed characteristics under prevailing traffic conditions at a specific site along a roadway. Because traffic engineering demands the collection and analysis of immense amount of data for performing all types of traffic studies, it follows that spot speed study is also a vital element in traffic engineering. Now a day’s managing traffic within our communities is a growing task for traffic engineers. As traffic volume increases and public financial resources decrease, targeting improvement projects to predict growth patterns is censorious. This paper represents traffic condition of Barkatullah university route Bhopal NH-12 Madhya Pradesh.

1. INTRODUCTION Speed plays a life and death role in evaluating the safety of road network. Speed by definition is the distance travelled in unit time. The typical unit of speed is kilometer per hour (kmph) or miles per hour (mph). Basically there are two types of speed; time mean speed and space – mean speed. Space mean speed is the length of a road section divided by the average travel time of several vehicles over this specific section. The time mean speed (spot) speed is the average spot speed of several vehicles measured at a given spot.
1.1 Area of study Area of study is Hoshangabad road, near Barkatullah University, Bhopal; Madhya Pradesh is a NH-12 which connects Jaipur in Rajasthan with Jabalpur in Madhya Pradesh. The total length of NH-12 runs to 612 km starting from national highway7 in Jabalpur it runs northwards and ends at Jaipur at NH-11.

A. Introduction A spot speed study is made by measuring the individual speeds of a sample of the vehicles passing a given point (spot) on a street or highway. These individual speeds are used to estimate the speed distribution of the entire traffic Stream at that location under the conditions prevailing at the time of study. B. Uses of Spot Speed Data The result of spot speed studies are used for many different purposes by traffic engineers, including: 1. Establishing the effectiveness of new or existing speed limits or enforcement practices. 2. Determining appropriate speed limits for application. 3. Establishing speed trends at the local, state, and national level to assess the effectiveness of national policy on speed limits and enforcement 4. Specific design application determining appropriate sight distances, relationships, between speed and highway alignment, and speed performance with respect to steepness and length of grades. 5. Specific control applications for the timing of “yellow” and “all red” intervals for traffic signals, proper placement of signs, and development of appropriate signal progressions. 6. Investigation of high-accident locations at which speed is suspected to be a contributing cause to the accident experience. C. Data Requirements For this project the most important traffic characteristics to be collected from the Barkatullah university-Bhopal” include spot speed and flow. The key point of measurement is the vehicle volume count. Data was collected manually on 06.06.2017 during non-peak hour with short interval of 15 minutes and for each type of vehicles like cars, two wheelers, buses, utilities, trucks, multi axle trucks. From the flow data, flow and headway can derived. This study is used to determine the level of service for streets, document congestion and quantify the need for street.
