Effectively tackle vehicle pollution

In 2008, Italy's first traffic charge named 'Ecopass' was launched in Milan in an attempt to reduce road congestion and pollution levels as well as to boost public transport through the re-investment of the pollution charge revenues. Transport economist Cosimo Chiffi outlines the success of the project.

Background

The metropolitan area of Milan comprises around 4 million inhabitants and is the centre of the polycentric Lombardy region. Milan also has one of the highest rates of car ownership in the world, with 550 cars recorded per 1,000 citizens at the end of 2009. The high reliance on car use for travel in Milan, together with adverse geoclimatic conditions, results in high pollution levels.

In January 2008 the Mayor of Milan, Letizia Moratti, launched the Ecopass programme, a traffic pollution charge implemented as an urban toll for certain motorists travelling within a designated traffic restricted zone corresponding to the historic central area called Cerchia dei Bastioni, which covers around 8.2 km2.

The charging scheme is controlled by 43 toll gates, from 7.30am to 7.30pm, Monday to Friday. Ecopass is not a congestion pricing programme, like those implemented in London and Stockholm, but rather a variation of these: it was designed with the aim of targeting and charging the most polluting vehicles only, while drivers of green vehicles (cng, lpg, electric and hybrid) pay nothing and residents have some special rates.

Tariffs depend on the engine emission class by type of vehicle. For instance, car drivers pay 10 for a day ticket if they own an Euro 0 diesel car; but only €2 for Euro 1, 2 gasoline cars. The system is based on Automatic Number Plate Recognition (ANPR) technology. Cameras installed at each gate read plates so that the corresponding pollution standard is recorded and the charge is calculated.

Costs and benefits 2008-2009

The operating costs involved in implementing the Ecopass programme in the first year were around €6.5 million, while revenues were around €11.5 million, made up of Ecopass payments only. However, the real benefits to Milan were derived from reducing congestion and pollution through the program.

On average, car trips entering the city centre decreased by 14.4%, in the first year after the introduction of Ecopass. This was clearly reflected in a reduction of PM10 (-23%) and CO2 (-15%) inside the charging area. Car traffic outside of the central area also decreased, by 3.4%. There was a societal benefit through better takeup of public transport in the city: the Milanese public transport company registered a pronounced increase in passengers using the Metro (+6.2%) but also in total on the whole network in the area (+5.7%).

Project:
Cut traffic pollution and congestion in Milan, Italy

Operating Cost 2008-2009:
€6.5 million approx

Benefits:(first year)
•Toll revenues €11.5 million in 2008
•14.4% fewer car trips in target area
•Pollution cut by 23% PM10 and 15% CO2
•Increased use of public transport
•Dramatic increase in green vehicle useIn 2010 the pollution charging system started to lose its benefit over time because of the renewal of the vehicle fleet. Now, 80 per cent of the vehicles entering the traffic restricted zone do not have to pay any charge because they meet the required air quality standard. This has reduced the toll revenues to €10 million in 2009 and around €8 million in 2010, and the level of congestion has therefore increased by 1.8 per cent during the first 6 months of 2010 compared to the previous period in 2009.

The real benefit of the Ecopass programme was that it directly caused traffic composition to be modified. As expected, there has been a dramatic shift in the number of vehicles entering the charging area from tolled to toll-exempted vehicles: the most polluting vehicles now account for only 17 per cent, as against 47 per cent in 2008.

Looking to the future

In November 2010, an Advisory Committee nominated by the Municipality has suggested to follow the example of London: all vehicles entering the charging zone should have to pay a charge of €4 or even more.

    Although urban traffic control and parking management are inextricably linked in so many ways, there remain fundamental differences which undermine closer integration. Car parking guidance systems can have a significant, positive impact on congestion in town and city centres, however conflicting business models still stand in the way of the more profound integration of car parking management and Urban Traffic Control (UTC) systems.

The coalition government will provide 75 per cent of the cost of installing new charge points. This can be claimed by: people installing charge points where they live; local authorities installing rapid charge points to facilitate longer journeys, or providing on-street charging on request from residents
