Question: What is the primary requirement for the communication service between Road Side Units (RSUs) and the Traffic Control Centre (TCC) in Intelligent Transport Systems (ITS), considering the need for real-time data processing and relay?
Option 1: High-bandwidth connections (up to 100 Mbit/s per RSU) with moderate latency tolerance (100 ms)
Option 2: Low-latency connections (10 ms) with high-capacity bandwidth (up to 1 Gbit/s per RSU)
Option 3: Moderate availability (99%) with variable latency and bandwidth adjusted on demand
Option 4: Low-latency connections (10 ms) with very high availability (99.9999%) and sufficient backhaul capacity (up to 10 Mbit/s per RSU)
Explanation: The correct answer reflects the tight end-to-end latency requirements for real-time data processing and relay between RSUs and TCC, coupled with an extremely high availability requirement to match or exceed existing wired technology reliability. Additionally, it acknowledges the need for sufficient backhaul capacity to handle aggregated data from large areas, as emphasized in ITS infrastructure backhaul requirements.
