Traffic volume trends matter as well as current levels. If the Hornsby area has major road infrastructure under construction or planning approval, such as a motorway extension, a new interchange, or a development that will add significant vehicle trips, the current AADT may not reflect what residents will experience in five years. Cross-reference the Development Pipeline card to check whether any approved projects in Thornleigh 2120 are likely to affect local traffic patterns.
