Speed study analysis

  2. 2. title of Study Speed Analysis of traffic Data using Spot speed Study
  3. 3. objectiVe • To Determine the Upper & Lower Values or speed limit regulation of mixed traffic flow • To Determine the Design speed for checking the geometric Design Elements of the highway
  4. 4. Scope
  5. 5. Study AreA • Our Study Area was the road outside NICMAR Gate no: 1 • This road has quite a number of small shops on one side and is located close to MITCON university as well. • We feel this road was best suited to conduct our analysis as this is used quite frequently and would provide us with a lot of readings that will help improve our accuracy of our outcome
  6. 6. GEOMETRICAL DIMENSIONS OF THE ROAD Length – 50m Width – 19m Carriage way- 3.75m No shoulders provided.
  7. 7. PROCEDURE • Two reference points were taken and measuring tape was used to measure the distance between the points. • Chalk was used to mark the two points. The two observers were stationed at these points. • An observer stood at the reference point where the enoscope was fixed. Every time the image of a passing vehicle is seen through the enoscope, the stop watch is started.
  8. 8. •The second observer would then stop the stopwatch whenever he observed the same vehicle pass the second reference point. •The distance apart and the time taken for each vehicle to cover the distance were used to calculate the speed of each vehicle
  9. 9. StatiStiCal MEthOD(EQUiPMENt USED) ENOSCOPE: • This device, also known as the Mirror-box, is an L-shaped box, open at both ends, with a mirror set at a 45-degree angle to the arms of the instrument. • The instrument bends the line of sight of the observer so that it is perpendicular to the path of the vehicle. • The stop-watch is started as soon as the vehicle passes the first reference point and is stopped as soon as it passes the observer. • The method can be used with one enoscope or with two enoscopes.
