What does 9.4 require?

A bus (other than a dedicated school bus) with more than 32 fixed seats must have at least 2 allocated spaces and a bus with fewer than 33 at least one, in each case additional to the fixed seating capacity. A ferry must have at least 2 allocated spaces for its first 32 passengers of capacity and 2 more for each additional 100. Each rail, tram or light rail car must have at least 2 allocated spaces, up to 8 of which may be consolidated in one car of a set, and where classes of travel differ allocated spaces must be provided in each class. An operator need not provide allocated space in an aircraft or coach where every passenger uses a fixed seat.

8.1 Boarding points: a firm, stable surface for safe boarding device deployment and a kerb at least 150 mm high; bus, tram and light rail boarding points no steeper than 1:40 longitudinally (or matching a steeper road where that is needed for deployment) with crossfall to clause 7.1(d) of AS 1428.1 (2021); train nominated assistance points with staff communication where independent boarding is impossible; a car marked accessible only if it reaches a seat, a priority seat, an allocated space and an accessible version of any other facility

8.2 Boarding devices and ramps: a manual or powered device at any accessible entrance with a vertical gap over 12 mm or horizontal gap over 40 mm, available at all designated stops and deployed on request, at least 800 mm wide with a slip-resistant surface to clause 4.1 of AS 1428.1 (2021), rated and labelled for 300 kg; boarding ramps to clauses 7.1(d) and (e) of AS 3856.1 (2021) with 65 to 75 mm edge barriers on portable ramps and slopes of 1:14 unassisted, 1:8 if 1520 mm or shorter, 1:4 assisted; hail-and-ride boarding at accessible points
8.6C Removeable gangways on ferries: long enough to keep safe clearance over the tidal and freeboard range and mechanically secured both sides; continuous handrails on both sides at least 1000 mm high and 800 mm apart with 30% luminance contrast and domed warning indicators at interruptions; upper and intermediate side barriers on stanchions no more than 2150 mm apart, with 65 to 75 mm edge barriers where the gap below the lowest rail exceeds 230 mm; direct assistance where any part exceeds 1:8; slip-resistant surface with a 50 to 75 mm contrasting leading-edge strip; designed and tested to 5.5 kPa and a 5000 N point load and proven by a practical boarding trial
8.7 Requesting a boarding device: a real-time means for a passenger to tell the operator they need the device to alight, with any signalling device in the allocated space, a 25 mm control operable with one open hand to clauses 10.4.3(c) and 10.4.4 of AS 1428.1 (2021), 2.5 to 5 N button force with an integral light and hearing augmentation on any audio system; a means to request the device to board, located at the boarding point to clause 10.4.3 of AS 1428.1 (2021)
8.9 Lead stops, passenger loading zones and taxi ranks: lead stops at bus stations, zones and interchanges identifiable and distinguishable to people with disability; loading zones and ranks within or associated with premises or infrastructure have an accessible first and last space (the only space if there is one) to clauses 2.2 to 2.5 of AS/NZS 2890.6 (2009), a firm level boarding area linked by access path to the main entry and other boarding areas, warning tactile indicators where they join a carriageway at grade and a kerb ramp to clause 10.7 of AS 1428.1 (2009); on public streets, accessible first and last spaces to clause 4.5.2 of AS 2890.5 (2020) with tactile indicators and bollards at grade and kerb ramps behind the space; a public street taxi rank connects to an access path and meets the boarding point surface and kerb rules
