Introduction

The safety considerations of pedestrians using road bridges, footbridges and similar elevated structures

require the installation of special road restraint systems, so called pedestrian restraint systems or

pedestrian parapets.

Pedestrian parapets are used to prevent people from falling off a bridge or other type of elevated

structure.
Aspects included in the Technical Report are:

a) safety in use for pedestrians and other highway users (excluding motor vehicles);

b) the safety considerations of pedestrians using road bridges and footbridges and similar structures;

c) analysis and test methods;
d) durability;
e) labelling and marking.

4 Requirements
4.1 General

Pedestrian parapets should be designed and/or tested and should conform to the requirements of this

Technical Report.

Where a vehicle restraint system is required to also function as a pedestrian parapet, the requirements

of EN 1317–5 should be met.
Figures in Annex E illustrate the constituent parts of a pedestrian parapet.

Manufacturers may provide other design types which are not shown in Annex E provided they comply

with the requirements of this Technical Report.
4.2 Construction
4.2.1 Assembly

Design, drawing, installation and maintenance instructions should be provided describing the measures

that have to be taken in order to achieve the following performances where they form part of the

pedestrian parapet:
a) a continuous flowing alignment;
b) smooth surfaces;
c) the absence of sharp edges that could cause injury to users;
---------------------- Page: 13 ----------------------
SIST-TP CEN/TR 16949:2016
CEN/TR 16949:2016 (E)

d) the provision for expansion, contraction and movement of the main structure (e.g. under traffic

loads and temperature effects) so that these do not endanger the performance or flowing

alignment;
e) the avoidance of corrosion pockets;
f) the provision for adequate drainage in hollow sections and channels;

g) the compatibility between component parts so that there is avoidance of electrolytic action;

h) that fixings and fittings cannot be loosened without using tools;

i) to demonstrate the ease of assembly at site location, the ease of maintenance and repair including

the replacement of parts;
j) finish and surface protection;
k) any special provisions for end posts/panels.
NOTE A method for ensuring a smooth finish is described in Annex G.
4.2.2 Optional facilities
The following optional facilities may be declared:
a) safety provisions for maintenance personnel;

b) provision for the fixing of a safety harnesses to support the weight of maintenance personnel to be

fixed to the posts;
c) special provisions for the safe passage of cyclists;
d) the manufactured height of a kicking plate;

e) the manufactured height of solid infill where horses and cattle are expected to use the bridge or

structure, the position of the infill is to be specified;

f) measures to prevent snow, debris and other hazards from falling on to traffic below the bridge or

structure;
g) the provision of a plinth, which shall have a minimum height of 50 mm;
h) specification for the provision of a steel cable inside the handrail;
i) avoidance of footholds to discourage climbing;
j) provision for intervisibility;
k) meeting the requirements of EN 12767.

4.3 Geometrical requirements
4.3.1 Height of manufactured product

The height H of the manufactured pedestrian parapet should be declared. Where the pedestrian

parapet is to be installed at an angle, the vertical height H should be declared m; see Figure 1.

The overall height H of the pedestrian parapet is related to Hp but depends on the location of the

fixing. See Figure 1 for examples. Where the post height exceeds the height of the top horizontal rail the

declared height should be to the top of the top rail.
Table 1 — Minimum heights
Height
Height (H )
A 1
B 1,1
C 1,2
D 1,4
F 1,6
E 1,5
G 1,8
Height should be measured with equipment that accords to EN ISO 9001.
4.3.2 Spaces and voids

The spaces and voids should not allow the passage of a spherical object with a diameter D . The

maximum value of D should be declared as D . Various values for D should be declared in relation to

b s s
height, see Figure 2.

Determination of D should take account of manufacturing tolerances and measured from a sample

(using callipers) and/or an analysis of the manufacturing drawings.

120 D = 120
130 D = 130
150 D = 150
300 D = 300
500 D = 500
NOTE The selection of void size(s) may have implications for

i) the avoidance of footholds which could make provision for persons to climb the pedestrian parapet

(e.g. minimum height 1,1 m and no horizontal ledges on traffic face greater than 15 mm);

ii) visibility (transparency/intervisibility) for drivers particularly at road junctions where there is a

need for side visibility (e.g. percentage of clear view area through parapet when viewed at a

specified angle);

iii) the avoidance of objects being thrown through the pedestrian parapet onto traffic below (e.g.

limiting a void/space size to 5 mm).

The above implications are mainly related to the site location of the pedestrian parapet which is not an

issue for this Technical Report and further guidance on the selection of sizes may be found in guideline

requirements prepared by Member States.
