Sub-problem 2d - Page 7 of 7 Sub-problem 2d: How Can We Improve the Level of Service at the Ramp Junction at the Northbound On-Ramp to I-87? The table below shows the effect of increasing the acceleration lane from 500 (existing condition) to either 1,000 feet or 1,500 feet. Again, as with the addition of a lane to the ramp, the effect is not significant. In fact, as we saw before, the demand still exceeds the capacity of the merge influence area; and we cannot depend on the results from the HCM model for this analysis.
