Please refer to ‘Barrier free footways’ for further information • Sightlines at crossings should not be obstructed by street furniture, plantings or parked/stopped vehicles • Crossings should not be located where sharp bends in the road occur as this may create blind corners and reduce driver awareness to stop within a safe distance Figure 140: Controlled crossing types Controlled crossings Single stage signal controlled Zebra crossing [Part E – Physical design and materials] Crossings 142 All round Pedestrian comfort • Both the footway and the crossing should be fit for purpose such that pedestrians are not overly constrained on the crossing or in the waiting area. Refer to our Pedestrian Comfort Guidance for London (2010) to determine the required levels of service • A 5,000mm wide crossing or similar is recommended where footways are narrow (less than 3,000mm) to increase waiting space and minimise obstructing pedestrian flows on the footway • At-grade crossings are preferred to subways and footbridges, to better serve pedestrian desire lines and facilitate greater priority for pedestrians Single stage signal controlled with central refuge Straight staggered crossing Two stage staggered • At especially busy crossings, for example outside stations, the designer should review the potential for footway widening and the provision of crossings wider than 5,000mm • Single stage crossings are preferred to staggered arrangements, to better serve pedestrian desire lines and facilitate greater priority for pedestrians

Selection should be based on traffic volumes, speed and pedestrian flows, as well as whether the crossing is at a junction or standalone. Pedestrian crossing facility (Ped-X) This is the preferred crossing for all new, modified and modernised signal layouts. The layout appears similar to a pelican crossing with far-sided pedestrian aspects, but the traffic light sequence is as a signalised junction, has no flashing amber vehicle signal and usually includes a countdown timer. Figure 141: A Ped-X crossing on Harrow Station Road with no pedestrain countdown timer Layout criteria Straight-across Ped-X crossings Preferred minimum crossing width 3,200mm Maximum crossing width 10.0 metres Dropped kerbs 1:20 preferred to 1:12 (maximum) Additional requirements where a central refuge is provided Recommended minimum central refuge depth 2,000mm Recommended minimum central refuge length 7,200mm Kerb upstand around central refuge 125mm Additional requirements for staggered Ped-X crossings Preferred minimum central refuge kerb to kerb 3,000mm Minimum stagger distance between crossing points on central refuge Stagger for all two-way roads Recommended minimum distance from uncontrolled junctions to primary signal pole 4,000mm recommended. Relaxations may be permitted with SDRG approval Left stagger to face oncoming traffic, unless otherwise agreed with SDRG 20.0 metres Good practice • Countdown timers should be considered for all Ped-X crossings • Signal timings should be appropriate to pedestrian flows and traffic volumes • All signal schemes are required to have a design and safety check in line with the Design Standards for Signal Schemes in London • Tactile rotating cones should be fitted to all controlled crossings • Audible bleepers should be fitted to standalone signal controlled crossings and ‘all round’ crossings at junctions as detailed in DfT Traffic Advisory Leaflets 4/91 and 5/91
