Compare Model Results
This section compares the model results between version 9.1.0 and version 9.0.2.
Road Volume Comparisons
The comparison between daily volumes at the segment level can be found in Figure 1 for 2019 and 2050. Decreases in volume in version 9.1.0 compared to version 9.0.2 are shown in blue, while increases are shown in red. Figure 2 shows a similar comparison, displaying medium plus heavy truck volumes.
For 2019, there are a few volume differences for all vehicles and trucks due to segment fixes. Other differences are negligible.
For 2050, there are a few volume differences for all vehicles and trucks due to segment fixes and project updates. Other differences are negligible.
Transit Comparisons
Version 9.1.0 showed a slight increase in transit trips compared to version 9.0.2 in 2032, 2042, and 2050 (see Figure 3 through Figure 9). The total transit trips in 2050 for version 9.1.0 is 342,000 daily trips compared to the version 9.0.2 model that showed 337,000 daily trips, which equates to 1.5% more trips.
Commuter Rail saw the greatest increase in trips, likely due to project updates. Express Bus saw a slight decrease in future trips, most likely due to the increase in trips to Commuter Rail since they compete for trips in similar markets. BRT, Core Route, and Local Bus trips remained relatively unchanged.
