Improving Road Safety

December 22, 2011


Towards complete road safety management

India’s highways are increasingly becoming killing fields. The country has one of the highest rates of road accidents in the world with about 500,000 accidents a year. Some 130,000 people lose their lives each year, and another 500,000 or so are injured. In fact, more lives are lost in road accidents in India than in epidemics, natural calamities or wars put together. Within India, Tamil Nadu has recorded one of the fastest increases in the number of vehicles on the roads and the maximum number of fatalities in the country. About 150 accidents take place per day on average, claiming around two lives every hour.

In April 2007, Tamil Nadu became the first state in the country to announce a Road Safety Policy. This was followed, in 2009, by a Road Safety Action Plan. As part of the Action Plan, an easy-to-use bilingual software package - known as the Road Accident Data Management System (RADMS) - was developed, with the help of an international consultant, under the World Bank-supported Tamil Nadu Road Sector Project. The GIS-based RADMS software geographically maps all road accidents that take place on Tamil Nadu’s national and state highways, as well as on urban and district roads. The system identifies the most accident-prone spots and displays crash trends and other information at the click of a mouse. The RADMS software, developed after detailed consultations between the police, transport and highways departments, has been helping the authorities analyze the ‘how’, ‘where’ and ‘why’ of road accidents, and enabling them to plan and implement remedial measures. In the two years since the system has been operational,
nearly 3000 accident-prone spots have been identified. The implementation of road safety measures based on this analytical data has brought down the number of accident fatalities in Tamil Nadu from 13.39 for every 10,000 vehicles in 2006 to 10.09 in 2010, exceeding the targets set by the state.

The RADMS software, developed at a cost of Rs. 2.20 crores (about $500,000), has been deployed at all the state’s 1,400 police stations and personnel at each station have been trained in its use. While similar software was first used in Kerala, Tamil Nadu is the first state to deploy it extensively. The software is constantly being improved. It is planned to provide each police station with a hand-held GPS device to enable personnel to enter the details at the accident site itself. It is also planned to link the system with medical facilities across the state for quick attention to accident victims. The creation of a national road accident database along these lines can help to markedly improve road safety across the country..


In the past five years, the number of registered vehicles on Tamil Nadu’s roads has gone up by almost 40 percent - from 82 lakh in 2007 to 1.3 crore in 2010, or 8.2 million to 13 million. With more vehicles on the streets and little demarcation of lanes for those travelling at different speeds, road accidents in the state were rising. This was compounded by poor road conditions, little driver education, and poor enforcement of traffic rules.

To improve road safety, data was needed on the most frequent causes of accidents and the most accident-prone locations. The paper-based First Information Report process was not effective as it lacked important information, was cumbersome, and generated a heavy backlog of work at police stations. Moreover, actions between the key departments involved in road traffic management - police, highways, transport - were not coordinated, resulting in piece-meal efforts to improve road safety.

The first step to improve road safety was the development of a comprehensive data base on which appropriate road safety measures could be based. Accordingly, as part of its Road Safety Action Plan, the state engaged an international road safety consultant to develop a comprehensive bilingual software package to collect, analyze and generate crucial reports on road accidents on a day to day basis. Major stake holders such as the police, transport and highways departments were involved in the software’s development.


Accident analysis

RADMS is supported by a powerful analysis engine that enables the authorities to identify high-density accident locations and generate automatic vehicle collision diagrams. This is designed to assist road safety engineers in improving the safety of roads and intersections.

Kilometer Analysis analyses accidents along a selected stretch of road.

Grid Analysis looks at the frequency of accidents in a specified area and identifies accident hotspots.

Cluster Analysis provides an analysis of the density and severity of accidents in selected areas.

Monitor Sites Analysis provides a visual comparison of the severity of accidents on selected sites. It also generates reports and graphs showing the effect of remediation measures.

Collision Diagram Analysis analyses the general pattern of accidents in select locations, usually junctions.

Corridor Analysis locates high-crash concentrations within a corridor. It allows routes to be linked

together so that an analyst can assess the overall safety of a transportation corridor.

Link Node Analysis analyses accidents occurring between any two nodes in the road network and is used when no maps are available to enter accident details.

Safety Benefit Evaluations study the effectiveness of remedial measures to reduce accidents.

Stick Analysis gives a pictorial representation of accidents along a number of parameters.


RADMS produces over 60 standard reports andallows users to create their own reports using anyof the fields entered in the Accident Report Form.Accordingly, road traffic accident reports can begenerated district-wise on an hourly, daily, monthlyand yearly basis, identifying the times and days ofthe week when most accidents take place, the mostfrequent types of crashes at these sites, the kind ofvehicles most frequently involved, the most commoncauses of the accidents such as road and weatherconditions, alcohol use, etc. The broad range ofanalytical data generated enables the authorities toplan and implement appropriate remedial measures.


The RADMS system has been deployed at all the state’s 1,400 police stations. It has helped identify nearly 3,000 accidentprone black spots. This has led to a number of interventions that have reduced road accident fatalities in the state from 13.39 for every 10,000 vehicles in 2006 to 10.09 in 2010. It has also resulted in:

Better traffic management

With accurate and real time accident data replacing the voluminous FIR data, the police department has been able to effectively post personnel at critical traffic junctions, deploy radar at appropriate places to detect and prevent speeding, provide speed breakers at relevant spots, upgrade traffic lights, and enforce rules for the use of seat belt and helmets etc.

Better roads

The highways department has been able to improve road conditions where they are most needed such as by creating dividers in areas which have a high frequency of head-on collisions, upgrading unsafe road junctions, providing better street lighting, installing road signs, trimming trees and so on. Increased road safety awareness The transport department has been able to target road safety awareness programs for appropriate groups, such as providing compulsory refresher classes for drivers of heavy vehicles.

Better allocation of budget resources

The availability of accurate information has enabled the authorities to provide financial and economic justification for the allocation of budgetary resources to improve road conditions.

Road safety now high on state agenda

The provision of regular reports to the highest authorities in the state has raised the profile of road safety in Tamil Nadu. Moreover, each department now has ownership of road safety issues, and the people have access to accurate information empowering them to ask questions about the implementation of road safety measures.

Road Ahead

The RADMS software is constantly being improved. It is soon planned to provide a hand-held GPS devise to each police station, enabling personnel to enter details at the accident spot itself. The device will automatically pick up the date, time, and spot where the accident happened. Efforts are also on to link the system with medical facilities for quick attention to accident victims.
