General regulations 4.1. The design of route and sidewalk must ensure the accessibility and use by PWD. Surface of route and sidewalk is not sliding, slippery an does not have brusque change in elevation. At transport nodes, entrance ways to facilities must be sloping for PWD circulating and accessing to facilities. 4.2. Entrance ways and main axial road of promenade paths in parks, entertainment and recreation, tourism areas must be designed so that PWD could circulate. 4.3. On car parking and car waiting spots with calculation of using need by PWD, there must be arranged signposts, guidance posters. 4.4. Routes must be safe, easy to circulate without barriers and wide enough for wheelchairs to have free way when coming from opposite directions. At spots where roads cross through traffic routes, it must be arranged direction guidance paving plates and stopping plates reserved to blind people. 4.5. Facilities installed on routes and sidewalks reserved to pedestrians such as public phone stations, advertisement posters, suspended objects . must not impede normal circulation of PWD. 4.6. Routes and sidewalks must be sufficiently lighted, ensuring walkers not to be dazzled or covered, mostly at spots where there is change in elevation. 4.7. At transport nodes, besides the installation of lamp transport signals, signposts, guidance posters, it is advisable to arrange acoustic signals or Braille raised dots for guiding blind people to cross the routes. Signposts, guidance posters must be arranged at the right places and easily identified /recognized. Conventional symbols of signposts, guidance posters for PWD are in compliance with regulations in TCXDVN 264:2002 - Building and facilities - Basic rules of accessible design and construction for PWD. 5.

Slope of route surface mush be not less than 1/12 but not more than 1/20. 5.3. The design of routes and scaffold bridges with parts thereof reserved to pedestrians must comply with the following regulations: - Maximum longitudinal slope must comply with regulations in table 2. - Length of longitudinal slope must be less than regulated in table 3 - Width of the path reserved to pedestrian not less than 2 metres Table 2: Slope of route surface Conditions Maximum slope i (%) Routes in plain’s region, cities Routes in region with hard relief 2.5 3.5 Table 3: Limit of length in longitudinal slope Slope i (%) Length of sloping route (m) < 2.5 2.5 3.0 Unlimited 250 150 3.5 100 5.4. At transport nodes, route crossing ways reserved to pedestrians, entrance ways to facilities, must be arranged sloping path to sidewalk by pavement slabs. Type, condition for use and requirement on designing pavement slabs sloping path must comply with following regulations: a) Pavement slabs sloping path with three sides (see fig.1) - Outward projection of pavement slabs in main side slope should not exceed 20 mm; - Slope of main side sloping slab should not exceed 1/12 - Slope of two lateral sloping slabs should not exceed 1/12 - Width of main side sloping slab should not be less than 1,200mm Note: Sloping way of pavement slabs inclined in three sides is usually adopted in cases on pedestrian path there are no facilities or green plants. Fig 1: Sloping way of Pavement slabs inclined to three sides b) Sloping way of pavement slabs inclined to one side (see fig 2) Fig 2: Sloping way of pavement Slabs inclined to one side - Outward projection of pavement slabs in main side slope should not exceed 20mm; - Slope of main sloping side should not exceed 1/12 - Width of main sloping side should not be less than 1,200mm - Width of pedestrian way should not be less than 2.0m Note: Sloping way of pavement slabs inclined to one side is usually adopted in case between pedestrian path and pavement slab there are facilities or green plants. c) Sloping way with pavement slabs along pedestrian path (see fig 3): - Outward projection of pavement slabs in sloping side should not exceed 20mm; - Slope of sloping side should not exceed 1/20 Note: This type of sloping way is usually adopted to entry/exit path of by-streets, front yard of building Fig 3: Sloping way With pavement slabs along pedestrian path 5.5. Sloping way with pavement slabs arranged at road crossing spot reserved to pedestrians (see fig 4) Pedestrian path Sloping way with Pavement slabs Part of road reserved to pedestrians Fig 4: Position of sloping way with pavement slabs at crossing spot reserved to pedestrians 5.6. At places where there is sloping way with pavement slabs, it is necessary to arrange signpost prohibiting mechanized vehicles to park there. 5.7. On sloping way with pavement slabs, needless to design handrails. 5.8. Surface of sloping way with pavement slabs must be made by non- slippery materials 5.9. The partitioning strips on pedestrian path must cross through the route. In traffic island, they should not be made higher than road surface, as shown in fig 5. Fig 5: Relationship between partitioning/ dividing strips, traffic island with part of road reserved to pedestrians. Pedestrian path 5.10. Traffic islands arranged on transport nodes should have sloping ways with pavement slabs, three sides at both side walks with length not less than 1,200mm, with not less than 900mm (see fig 6) Fig 6: Sloping way toward sidewalk at traffic islands a) Crossing through island; b) Slop way with pavement slabs on sidewalk. 5.11. On ways reserved to pedestrians and at entrances in public facilities, it is necessary to arrange sensitive paving slabs for guiding blind people in circulation. Sensitive guiding paving slabs are divided in two types: orientative paving slabs with salient strips guiding walking direction and pace stopping slabs with round points showing barriers before sight. Paving slabs are preferably painted in dark yellow colour. 5.12. Sensitive direction guiding slabs are shown in fig 7 (of which round ones are usually adopted at humid wet places). Materials for producing paving slabs must be non slippery. Note: Direction guiding slabs could be produced from natural rubber or synthetic rubber. 5.13. Direction guiding slabs are usually arranged on direction toward facilities, stair cases, lifts, sloping ways, traffic nodes, car parking ground, station yard, station, spots where there is change in the walking direction and places with danger warning in the area. Various kinds of Fig 7: sensitive paving slabs 5.14. On the entrance way to facilities, direction guiding slabs must be continuously arranged. Before the entry/exit path, pace stopping paving slabs must be laid. Width of paving slab must be less than 600mm, see fig 8 Pace stopping paving slab Direction guiding slab Fig 8: Arranging sensitive paving slabs in pedestrian way Sloping way with pavement slabs 5.15. Sensitive paving slabs in part of route reserved to pedestrians are placed at 300mm from the rim of sidewalk or inside of a paving brick for walker. Direction guiding paving slab and pace-stopping paving slab must be placed at right angle (perpendiculary). Width of paving slab must not be less than 600mm, see fig 9. Direction guiding paving slab Pace stopping paving slabs Sloping way with pavement slab Fig 9: Arranging sensitive paving slabs in part of route for pedestrians 5.16. At car waiting spots, 300mm from sidewalk rim or inside of a paving brick for walkers, it is necessary to lay direction guiding slabs. At places with the car parking signpost, it is necessary to install direction guiding paving slabs and pace stopping slabs, perpendiculary to each other . Width of paving slabs is no less than 600mm, see fig 10. Direction on guiding paving slab Car parking sign post Fig 10: Arranging sensitive paving slab at car waiting spots 5.17. Where in the interior side of entry way to facilities, there is a row of green trees with an elevation of 100 mm higher than the surface of pedestrian way, then at the deviation, it is necessary to use prolonged direction guiding paving slab, see fig 11. Fig 11: Arranging direction guiding pavement slabs in pedestrian way 5.18 . On the line of pedestrian way, it is necessary to restrict barriers likely to appear on the way. a) Cover lid of gas pits, underground pipeline on pedestrian way must be in the same level with soil surface, and absolute ban of using diamond-mesh cover lid; b) Dimensions of hole for storm/rain water drainage slab laid on the way must not be more than 20mm x 20mm; c) Interval between suspended objects in the space of pedestrians must not be less than 2.0m; d) At road crossing path reserved to pedestrians with direction guiding paving slabs and sloping way with pavement slabs, it is prohibited to arrange rain water collection pit; e) On pedestrian way, if it is necessary to preserve ancient trees, vestiges, or if there are protruding barriers, then protection measures must be taken, or warning/guidance posters or direction guiding paving slabs must be installed. 5.19. Scaffold bridges and tunnels with part of way reserved to pedestrians, being stepped, must comply with following regulations: a) Height of step being no more than 150mm, width of step surface being no less than 300mm; b) Number of steps in each flight should not exceed 18. If there are more than 18 steps, it is necessary for arranging a landing. Width of a landing being not less than 1,500mm. When a flight changes direction, the clearance width of the landing is not less than the clearance width of that flight. 5.20. Sloping way in part of route reserved to pedestrians of scaffold bridge and tunnel must comply with following regulations: a) Slope must ensure to be in a range of 1/10 1/12 b) Every time sloping way ascends 1.80m or at direction changing spot, it must be arranged a landing with width not less than 2.0m. c) Clearance height on part of route reserved to pedestrians of scaffold bridge and tunnel must not be less than 2.0m; [...]... cross the route Calculated time interval as per walking velocity of PWD is 0.5 m/s CONTENTS Foreword 1 QCXDVN 0 1:2 002 - Building code of construction accessibility for PWD 2 TCXDVN 26 4:2 002 - Building and facilities - Basic rules of accessible design and construction for PWD 3 TCXDVN 26 5: 2002 - Route and sidewalk - Basic rules of accessible design and construction for PWD ... handrails must be arranged on both sides or on a side adjoining the partition wall Requirements on detailed design of handrails are shown in the standard TCXDVN 26 4:2 002- Building and facilities - Basic rules of accessible design and construction for PWD Note: Where sloping way in part of road reserved to pedestrians on the tunnel could not be arranged, it is possible to use elevators or specialized devices .
