 Your assignment is to determine the level of service (LOS) at which a local intersection is functioning during its peak period. If the measured LOS is unacceptable, you are to propose changes to the signal-timing plan that would correct the problem or show why an easy solution does not exist. Your instructor may select an intersection in your area for this analysis, or you may be allowed to select an intersection. In addition, your instructor may indicate specific movements that are of particular interest. Tasks to be Completed Task 1. Measure and record the dimensions of the study intersection. Prepare a dimensioned drawing of the facility. Task 2. During the peak period, record the average lengths of the various signal indications. You should record enough information to accurately describe the current signal-timing plan for the intersection. Task 3. During the peak period, record the number of vehicles passing through the intersection within each of the various movements. Make sure you record enough information to complete the required LOS computations. Task 4. Determine the LOS of the various intersection movements using the information you have collected. Record any interesting observations. Task 5. If the LOS analysis reveals a problem, propose a new signal-timing plan that would correct the problem or show why an easy solution does not exist. Task 6. Prepare a brief report that outlines your work and summarizes your conclusions and proposals.
