With a predicted 60% increase in traffic by , the Government has been forced to look at how best to increase capacity without widening the road. the opening up of the hard shoulder to traffic at times of peak congestion. Highways England's analysis of the safety of smart motorways with all lanes. This literature review investigates the relationship between congestion and safety at road sections of the main road network. (mainly motorways) and specifically.

Motorway crash barriers also known as safety barriers are designed to prevent vehicles from crossing from one carriageway to the other and to prevent vehicles from impacting or entering roadside hazards.

The barriers are also intended to absorb some of the energy from the impact caused by the vehicle striking it and to redirect the vehicle along the line of the barrier so that it does not turn around, turn over or re-enter the stream of traffic.

This is called containment. Safety barriers are only used where the consequences of a vehicle striking a barrier are considered likely to be less serious than if the vehicle were to continue unrestrained. The working width is the width of the barrier plus the amount of deflection that occurs when the barrier is impacted. A barrier designed for normal containment would be tested with a vehicle of 1. High containment barriers would be tested with a heavy commercial vehicle, up to 38 tons, travelling at 40mph, hitting the barrier at an angle of 20 degrees.

They can either be flexible, such as a steel wire rope or a steel beam or rigid such as concrete barriers. The Highways Agency has stated that it would be willing to consider other materials or systems if they were to meet ES test standards. To read about different types of barriers click here. Regulations in the UK In the UK, the minimum length of barrier that can be installed in advance of a hazard, including at the approach to a bridge over railways, is 30m.

However, on motorway and trunk road bridges over railways in the UK, the majority of approaches have safety barriers in excess of 30m in length.

The minimum length of barrier to be installed at the approach to a bridge in other countries ranges from 16m in Austria to 98m in New York. The specifications range from 0. However, the distance between the top and centre of a barrier beam will depend on the design of the barrier system. Most countries use barriers with the same strength as the UK for the containment of cars. For the containment of heavier vehicles, other countries use either the same or lower barrier strength than the UK.

It concluded that the Department for Transport guidance on the design of crash barriers, which state that safety barriers should be a minimum of 30m long, had not been breached. However, the problem with this Government guidance is that there is no recommended length for barriers at different sites.

Experts fear that the minimum length of 30 metres which is necessary for some types of barrier to be able to absorb an impact is being applied without local aspects, such as curves in the road, being taken into account. Regulations say a barrier has to be positioned anywhere that a vehicle can leave the road and find its way into a dangerous situation. This breached their regulations. The appropriate location for a barrier may not be on railway property and the railways have no power to erect barriers outside their property or competence to design barriers from a road safety viewpoint.

Highways authorities have the capability and the powers to erect barriers on their side of the boundary, but have no specific duty in law or resources to help them do it.

In some cases the best barrier for protecting the railway may not be the best barrier in terms of road safety. Driver killed in flyover plunge A man died on 17 January after his car crashed through the barrier of an M8 motorway flyover near Glasgow and landed on a vehicle travelling below. The year-old driver, who was not named, died after his Mitsubishi 4x4 left the eastbound carriageway near Hillington and plunged 50ft onto a Honda Civic.

This type of barrier was chosen for its containment of vehicles and minimum effect on vehicle occupants. International survey In a survey carried out on behalf of the Highways Agency and Britpave examining concrete barrier usage in Europe found that every country that responded used concrete barrier systems. The survey also found that several countries preferred concrete barriers to steel barriers in central reservations, especially where traffic was heavy.

Reasons for the preference included safety, low maintenance, less risk of crossover incidents and fewer interventions for repair. The policy stated that in most cases, when concrete barriers are struck, they do not need to be repaired and also do not need as much regular maintenance as steel barriers, therefore minimising the exposure and risk to road workers. Existing steel barriers will only be changed when they need replacing.

The Highways Agency has highlighted a potential problem that concrete barriers may pose additional risks in certain circumstances where emergency services need to get through the barriers to reach incidents.

Adpated from original article by the Huffington Post Then there is a general lack of awareness of basic traffic rules, absence of traffic signage and lights, and dangerous road conditions. Finally, neither passenger nor commercial vehicles come equipped with basic safety features. It is common to drive without a license or seat belt. The general public are reluctant to help accident victims for fear of getting caught up in court battles, whilst medical help is often too little too late.

So, unlike other developing countries such as Brazil and Russia, the number of people dying on the roads of India shows no sign of falling. Unlike other developing countries such as Brazil and Russia, the number of people dying on the roads of India shows no sign of falling. There is no shortage of government ministers, activists and non-government organisations NGOs trying to address this problem.

The emergency corridor

The latter hopes to increase acceptance and recognition by drawing in celebrity sponsors such as Bollywood star Shah Rukh Khan. Community programmes aim to build 'road safety as a mass movement' especially amongst the youth who tend to suffer disproportionately in accidents.

According to Prince Singhal, these programmes are necessary to help strengthen the core goals of India's road safety programme or the "Four Es" of road safety -- Education, Engineering, Enforcement and Environment. However, initiatives undertaken in the past five years have been unsuccessful according to the International Road Federation IRF.

A lack of "legislative and executive interventions" is largely to blame. With a strong culture in India, is road safety embedded in that?

During congestion: the emergency corridor

Initiatives undertaken in the past five years have been unsuccessful according to the International Road Federation IRF. Piyush Tewari, chief executive and founder of the SaveLIFE Foundation, says, "the report should be an eye-opener for our law makers, as it categorically states that Indian road safety laws do not meet the best practice requirements for four of five risk factors -- enforcing speed limits, prevention of drunk driving, safety of children and use of helmets.

Government ministers insist India is committed to "improving safety, efficiency and sustainability in the transport sector. It is working to increase awareness of road safety, the importance of obeying traffic rules and driving safely.
