Miami, Oklahoma has three transportation analysis zones, and origin-destination
Transcribed Image Text:### Trip Productions and Attractions for Miami, OK.
#### Table 1: Trip Productions and Attractions
This table illustrates the number of trip productions and attractions across three zones in Miami, OK. Each zone is quantified in terms of the number of productions and attractions, leading to a total figure for the entire area.
| ZONE | | 1 | 2 | 3 | TOTAL |
|------|-----|-----|-----|-----|-------|
| PRODUCTION | | 250 | 450 | 300 | 1000 |
| ATTRACTIONS | | 395 | 180 | 425 | 1000 |
#### Table 2: Travel Times Between Zones (min)
This table presents the time, in minutes, taken to travel between different zones within Miami, OK. The values displayed indicate the direct travel time between each pair of zones.
| ZONE | 1 | 2 | 3 |
|--------|---|---|---|
| **1** | 1 | 6 | 4 |
