⢠The district tables show that the MORPC model produces reasonable user benefit results. The majority of user benefits occur in the corridor, with minimal level of benefits in intradistrict markets. The CBD district has the highest level of benefits in terms of attractions. ⢠Mapping the results provides a good tool to high- light the benefits and disbenefits of the project. The pro- duction map illustrates that a majority of the benefits accrue to people living in the corridor, especially by those living near the rail stations. The areas not receiving sig- nificant benefits reflect the longer travel times from the proposed project as compared with the existing bus ser- vice. Benefits are realized around stations near major employment areas, especially Ohio State University and the northern suburbs. ⢠The review highlighted that complex models using simplified networks still require well- coded networks and sound modeling procedures. The turnaround time to correct relatively small issues can be lengthy. For exam- ple, recalibration took 3 to 7 days, running the baseline alternative took 3 days, and processing a build alterna- tive took 1 day. ⢠Overall, the MORPC model produced good distri- bution results and user benefit results. Complex models are still susceptible to network coding issues and prob- lems, however. These problems may include network speeds, the need to revise transit access and path build- ing, and recalibration needs. It is also important not to underestimate the time needed to perform the analysis of various options.
