High-turnover hubs amplify small layout mistakes into daily delays. Here we translate kerb geometry, dwell times, and queue control into safe, efficient interfaces that protect pedestrians and glazing. You’ll size bays and turning paths, place signalling and PA, and decide where removable or automatic HVM bollards belong so crash rated bollard integrity is never compromised. Include one-sentence context that naturally links upward to the parent hubs (this section and the chapter hub). Add SIRA context with a link to SIRA Bollards (UAE) when relevant. Link installation pages only if helpful: What to Expect and Installation Guide.
828.1 Flow separation
Bus/taxi/private car lanes separated (215). HVM bollard lines protect pedestrian edges.
Start by separating flows so each user has a dedicated path and clear priority. Map the access & circulation study (215) and draw the approach vector corridors for taxis, buses, and private cars. Where pedestrian fronts are exposed, protect the kerb line with HVM arrays sized for credible worst-case impact energy.
Reserve a controlled entry for legitimate vehicles via vehicle access & traffic control. Use automatic bollards where frequent bus access is needed, and removable lift-out posts for infrequent maintenance entries. Keep clear-gaps compliant with clear-gap rules while meeting lane width targets.

|---|---|---|
| Performance | Tested system (bollard + foundation) | Crash standards overview |
| Operations | Throughput, fail-state, safety interlocks | Commissioning & safety tests |
828.2 Kerb geometry
Saw-tooth or straight stands; turning radii (325). Geometry mustn’t weaken crash rated bollard arrays.
Saw-tooth stands shorten dwell and ease egress but create bay-corner hotspots. Straight stands maximize queuing but can lengthen pull-out. Validate turning paths with turning & service access (325) and protect glazing using a frontage protection array if buses over-swing near shopfronts.
Never notch, offset, or reduce the footing that gives a crash-rated system its capacity. If utilities clash, consult foundation types and drainage strategy before shifting bollards off the defend line.
828.3 Dwell & queue control
Holding bays and marshals (821, 817). Control reduces unsafe stacking near HVM bollards.
Dimension holding bays so primary stands never back up across a protected kerb. Add a marshal line before the rank and use timed releases to flatten peaks. For event surges, see vehicle access lanes (821) and stadiums & events (817) for stewarded operations.
Monitor lane occupancy and spillback. If queues approach defend lines, add a stewarded gate or expand the holding pen so bollards are not routinely stressed by near-contact maneuvers.
828.4 Signage & PA
High-salience cues and announcements (353, 357). Reduce driver error.
Place gateway signage in the driver cone with consistent safety signalling (353) and conspicuous markings (357). Use lane identifiers and VMS to prevent wrong-lane entries that push vehicles toward pedestrian fronts.
Align the PA script with live operations: trigger boardings, stagger taxi releases, and announce disruptions early. Keep posts and signage outside the penetration line so nothing critical sits where a glancing impact could push it into crowds.
828.5 Ticketing & kiosks
Place kiosks outside impact paths (214). Crash rated bollard protection for glazing (234).
Ticket machines and kiosks attract queues; set them beyond the main run-up and away from corner throats. Use the approach paths (214) analysis to keep equipment off vectors a wayward vehicle might follow.
Where kiosks sit near shopfronts, add a short frontage array (234) or a tight corner chicane so glazing is buffered from low-speed overruns without obstructing pedestrian desire lines.
828.6 Accessibility
Boarding heights, tactile routes (238). Inclusivity with HVM bollard safety.
Coordinate platform heights with bus floor levels; where that’s not possible, set a standard boarding pad and keep it clear of bollard heads or handlebar traps. Provide continuous tactile routes & wayfinding (238) that bypass the arrays via generous refuge pockets.
Lighting, contrast bands on posts, and low-glare finishes improve detection without adding visual clutter. If an automatic lane crosses a pedestrian path, include audible beacons and safety edges tied into the interlock matrix.
828.7 Drainage & spills
Manage oil/fuel near pits (245, 616). Protect electrics and surfaces.
Mobility hubs get fuel and oil drips. Route carriageway runoff away from bollard drainage sumps (245) and equipment pits; include silt baskets and NRVs. Where HPUs or cabinets are present, elevate gland plates and maintain drip loops.
At the stands, use hard-wearing paving modules and plan spill-kit locations. For deeper pits or electrics, see equipment pits & sumps (616) and verify buoyancy checks where high groundwater is possible.
828.8 CCTV & ANPR
Coverage for disputes/security (534). Data links to KPIs (542).
Design camera views for boarding doors, queue lines, and taxi rank pockets. Coordinate with access control & CCTV (534) so ANPR validates taxi access without slowing lanes.
Push counters (ops/hour), cycle times, and alarms into the KPI set (542). Use heatmaps and queue pressure to tune steward positions; keep posts and poles outside the bollard penetration line to avoid debris hazards on impact.
828.9 Authority pack
Transport approvals and SAT proofs (717, 638). Evidence speeds acceptance.
Bundle drawings, swept-path checks, risk assessment, and the authority submittals (717) with crash certificates and as-tested configurations. In the UAE, include SIRA where in scope: see SIRA Bollards (UAE) for posture and tier expectations.
Before opening, complete a witnessed Site Acceptance Test (638) covering modes of operation, safety signalling, and emergency overrides. Keep a reset-to-normal checklist and archive the witness diary and video for future reference.
