Sub-problem 4c - Page 7 of 7 Sub-problem 4c: Peak Operational Analysis of Alternate Route 7 The tables below show the results for time periods 3 and 4. We note in the first table that the queue formed during time period 2 clears during time period 3, by the first minute in section 3 and by the third minute in section 5. You can see that the demand that wasn't served during time period 2 has been transferred to time period 3, since the volumes in sections 4 through 11 that actually use the facility exceed the original demand for these sections. For example, in section 5, the volume is 1,745, while the demand is 1,270. This means that a flow rate of 1,745 minus 1,270, or 475, has been transferred from time period 2 to time period 3. And since the demand for time period 3 is low enough, there is sufficient capacity to serve both the original demand (1,270), plus the transferred demand (475). During time period 3, all sections operate at level of service C or better, with the exception of section 5, which is still recovering from the queue, and operates at level of service E. The speed in section 5 is less than 20 mph during this recovery. But by time period 4, all sections of the freeway facility are operating at LOS B or better. All speeds exceed 40 mi/hr. And, once again, the demand equals the volume, indicating that all vehicles desiring to travel along the facility during time period 4 are served.
