<s>[INST] The next text is a question of a member of the European parliament:"According to a study published recently, traffic in Austria has grown much more than the population since the country joined the EU. The number of heavy goods vehicles alone is up 49%, due in part to the system of EU support. A good deal is already known about the negative impact of this gathering avalanche of traffic, particularly on the vulnerable Alpine region.   Whilst efforts are being made throughout Europe to cut emissions of pollutants by individual vehicles, technical advances are then wiped out by the increase in the number of cars and additional journeys made. The blame for this greater dependence on cars can be laid not just on poorly developed or poorly coordinated public transport networks, but also on urban planning developments such as the explosion in shopping centres located on the outskirts of town accompanied by the decline in local shops. Add to this longer journeys to work as a result of urban sprawl and greater flexibility in working hours and conditions and the car becomes a precondition for employment.   1.What successful measures have been taken in the EU to improve the public transport network?  2.Do any town planning concepts exist to check these developments or are there plans for strategies in this field?  3.How much thought has been given to a review of EU funding in this area, in order to prevent any further explosion in the number of heavy goods vehicles and cars?  4.What is the current status with negotiations on the Alpine Convention and are any fresh attempts being made to implement it?"
