Figure below shows an isolated intersection at Third Street and Ellis Avenue outside the CBD of a city. Third Street is one way in the NB direction with parking allowed on either side. Ellis Avenue is major arterial with s separate left-turn lane on the EB approach. Traffic volume counts at the intersection have shown that the growth rate over the past three years is 4% per annum, and it is predicted that this rate will continue for the next five years. The existing peak hour volumes and traffic characteristics are shown in Figure. Determine a suitable timing of the existing three-phase signal that will be suitable for traffic volume in five years. Assume that, except for traffic volumes, characteristics will remain the same. Also determine the LOS at which the intersection will operate. A critical (v/c) ratio of 0.85 or lower is required at the intersection. Intersection Third Street and Ellis Avenue Analyst Project No: VOLUME AND GEOMETRICS IDENTIFY IN DIAGRAM: 1. plumes 2.
