How much traffic flows through Summer Hill? The volume card below shows AADT counts from the nearest Transport for NSW monitoring points to Summer Hill 2130. Counts above 15,000 vehicles per day on a residential collector road typically indicate meaningful noise and air-quality impacts; counts above 30,000 on an arterial are associated with property price discounts on directly fronting lots.
If the AADT counts for Summer Hill are concentrated on one or two arterial roads, the practical impact on most residential streets is low. The key question is whether your specific property is on, adjacent to, or buffered from those arterials. A suburb-level traffic rating of "high" can mask very quiet residential streets that are simply near a busy road without directly fronting it.
