Question

Transcribed Image Text:**Problem 4: Zonal Traffic Interchanges**
The three traffic zones A, B, and C have interchanges as follows:
- Interchange from A to B (AB) is 10.
- Interchange from B to C (BC) is 15.
- Interchange from C to A (CA) is 20 (non-directionally).
**Growth Factors:**
- Zone A: 2
- Zone B: 3
- Zone C: 1
**Task:**
Using the Fratar method, compute the zonal interchanges for the forecast year.
**Diagram Explanation:**
The diagram is a triangular schematic representing the interchanges between the three zones:
- Zones A and B are connected with a line labeled "10."
- Zones B and C are connected with a line labeled "15."
- Zones C and A are connected with a line labeled "20."
Each line represents the traffic flow between the respective zones.
