Europes Approach to Safer Roads and MobilityPresentation Category:

Session 4B, SAFER ROADS & MOBILITY

Improving road safety, requires acting on the three pillars of the road safety triangle, i.e. the driver, the vehicle and the infrastructure.

Road Safety The essential role of the infrastructure

The ERF believes that, in recent years, the efforts in road safety have increasingly focussed on the vehicle and the driver, often neglecting the role of the infrastructure.

Source: ERF Road Safety and Road Restraint Systems

While acting on the driver and on the vehicle surely has its role to play.The ERF believes that investing in road infrastructure can offer fast and cost-effective solutions, that can reduce fatalities and related health care cost.

Road Safety The essential role of the infrastructure

In the USA half of highway fatalities are related to deficient roadway conditions -a substantially more lethal factor than drunk driving, speeding or non-use of safety belts.

Road Restraint Systems (RRS) are an essential component of a modern road infrastructure and constitute one of the most important lifesaving devices available to public authorities and road operators.They represent an immediately available solution that can, in addition to saving lifes, significantly reduce the accident related health care cost.

Road Restraint Systems A cost-effective solution

You get everyday new drivers on the roads.

Fasten seat belt Dont drink and drive

Stop speeding

You have to teach this and enforce this every day!

Investments in road restraint systems and forgiving roads will affective immediately and will be there tomorrow.

______________Savings = 365.000 per year !

That was easy

Now you think:How to do it in my area

European Norm 1317

EN1317 is mandatory for all CEN member states.They have to transfer this EU Norm into a national standard.

EN 1317 is the guideline for all road restraint systems.

Road Restraint Systems have to fulfil the demands of EN 1317 (part 1 to5).They have to prove this by presenting a Test Report (acc. to EN1317 part2).

EN 1317 - National Requirements

The EN 1317 is only checking the efficiency of the RRS. Design and / or installation guidelines have to be harmonised locally.

The RRS could be made of Wood, Steel, Concrete or other material.They can be piled in, free standing or anchored to the ground as longas they can prove that they are successfully tested according toEN1317.

EN 1317 National Decision

EN 1317 tells you under which conditions a RRS can get on the road in Europe

The national Road-Authorities decide which containment level will beinstalled and where

The minimum legal requirements are fixed on national level.(which Containment level is used in which specific location on the road)

System with Containment Level H4b (stopping a 38 ton truck at 65 km/h, 20 impact angle)

How to do it

To choose an adequate RRS you can go though the following steps

1) Identify a hazard, a dangerous section or an issue on your roads

obsticle

RRS

Working Width

Distance

Road

orslope > 1:3

Next

2. Eliminate or move the danger, hazard, obstical or isse !

3. If that is not possible choos an adequate RRS.

First you need to identify the distance between the road edge or theplace where can place the RRS and the obsticle

Working width, according to EN 1317

Working Widthe.g. 1,45 m = W5

Classes of working width

Levels of working width

W1 W 0.6 m

W2 W 0.8 m

W3 W 1.0 m

W4 W 1.3 m

W5 W 1.7 m

W6 W 2.1 m

W7 W 2.5 m

W8 W 3.5 m

Source: EN 1317 2

RRS Containment Level according to RPS

3. Working width can be identified by mesuring

Hazard / danger level

Design speed of the road(km/h)

Trafic volume

Likelyhood of leaving the road

4. The containment level can be identified by 4 steps

Finding the right RRS for different applications

3.3 Outer edge of carriageway(1) The hazard potential of danger spots at the outer edge of the carriageway is classified

according to four hazard levels:

Hazard level 1: areas requiring protection with special risks for third parties (e.g. potentially explosive chemical plants, heavily used stopping areas, adjacent sections of high-speed railways with permitted speeds > 160 km/h, buildings in danger of collapse),

Hazard level 2: areas requiring protection with risks for third parties (e.g. adjacent, heavily used footpaths and cycle paths, adjacent rail lines with more than 30 trains/24 h, adjacent roadswith ADT > 500 vehicles/24 h),

Hazard level 3: Obstacles with special risks for vehicle passengers (e.g. non-deformable, extensive obstacles vertical to the direction of the traffic, non-deformable, isolated individual obstacles, noise barriers),

Hazard level 4: Obstacles with risks for vehicle passengers (e.g. isolated obstacles which are deformable but do not buckle or shear off, intersecting ditches, ascending slopes (incline > 1:3), descending slopes (height > 3 m and incline > 1:3), stretch of water with a depth > 1 m, white water).
