Das Bundesministerium für Verkehr, Bau und Stadtentwicklung lässt im Rahmen des Nationalen Radverkehrsplans ein Verfahren entwickeln, mit dem Maßnahmen für den Radverkehr quantitativ bewertet werden können. Praxispartner sind die Städte Berlin und Hamburg.

Die Konkurrenz um die knappen kommunalen Mittel verlangt immer häufiger Nachweise über die Wirksamkeit der zur Durchführung vorgesehenen Maßnahmen. Aufgrund der schwierigen Nachweisbarkeit des Nutzens von Radverkehrsmaßnahmen werden diese häufig zugunsten anderer Projekte hinten angestellt.

Vor diesem Hintergrund initiierte das Bundesministerium für Verkehr, Bau und Stadtentwicklung das Forschungsprojekt "Kosten-Nutzen Analyse zur Bewertung der Effizienz von Radverkehrsmaßnahmen", das von der Arbeitsgemeinschaft TCI Röhling - Transport Consulting International- / PTV AG bearbeitet wird. "Fahrradmaßnahmen bewertbar machen" ist das Ziel der Arbeiten. Bis heute sehen Systeme zur Bewertung von Infrastrukturmaßnahmen, wie z.B. das Bewertungssystem zur Bundesverkehrswegeplanung, keine geeigneten Ansätze für die Bewertung von Radverkehrsmaßnahmen vor. Bewertung bedeutet dabei, dass die Kosten von Maßnahme den erzielbaren Nutzen gegenübergestellt werden. Durch das Forschungsprojekt sollen spezifische Indikatoren, die die Kosten und Nutzen von Radverkehrsmaßnahmen quantifizierbar machen, entwickelt werden, die dann später auch Eingang finden können in die gängigen Bewertungsverfahren.

Als Praxispartner konnten die Städte Berlin und Hamburg gewonnen werden, die durch ihre Mitarbeit das Projekt unterstützen und die praktische Umsetzung der Konzepte begleiten.

The report quantifies-for the first time-the national benefits of bicycling and walking.

‘In anticipation of expensive changes in our energy supply system and the challenges of reducing CO2 emissions, active transportation offers a welcome contribution to greenhouse gas reductions at a net cost savings. On a human scale, the health benefits from increased investments in safe and convenient infrastructure for bicycling and walking may very well turn out to be the most valuable "side-effect" of shifting our transportation policies. By accommodating bicycling and walking, federal transportation policy can help reverse the devastating trends in obesity that were aggravated by development patterns tailored to the automobile.
In times of economic hardship and fiscal constraint, investing in infrastructure for active transportation offers a highly affordable opportunity to create an immediate and long-lasting stimulus for our economy. Savings at the gas pump and reduced oil dependence, higher productivity of healthier workers and lower health care expenses, flourishing businesses and more valuable real estate, shorter commutes and reduced needs for road expansions are among the many economic benefits for us individually and as a nation.'
Investment in Bicycling and Walking Will Save Billions:
The report quantifies-for the first time-the national benefits of bicycling and walking.

Putting figures to facts, the report documents the transportation, energy, climate, public health, and economic benefits of bicycling and walking. Never before has the case been made so clearly that relatively modest federal investment in bicycling and walking can save Americans tens of billions of dollars each year. The report compiles success stories from communities across America to show the potential to realize these benefits.

The report reveals that the missing piece in America's transportation policy puzzle is active transportation: bicycling and walking. Although some may view active transportation as marginal, bicycling and walking currently account for 10 percent of all trips in America, and could play a much larger role if the federal government were to invest adequately in providing safe and convenient places to bicycle and walk.

"The report shows that modest increases in individuals bicycling and walking could lead to an annual reduction of 70 billion miles of driving, and more substantial increases could avoid 200 billion miles each year," says Thomas Gotschi, research director for Rails-to-Trails Conservancy. This could cut oil dependence and climate pollution from passenger vehicles by 3 to 8 percent, out-performing the historic contribution of other prominent solutions such as gas-electric hybrid vehicles.

"When communities invest in safe and convenient bicycling and walking facilities and connect them to public transit, good things happen," says Tim Blumenthal, executive director of Bikes Belong. "Beyond the crucial health and community benefits, bike sales increase and the bike repair business grows. This has been an outstanding year for sales of bikes used primarily for commuting and short trips, but it is just the beginning. This report clearly shows what is possible if we continue to invest in safe, convenient places to ride."

Authored and produced by RTC with funding support from Bikes Belong, the "Active Transportation for America" report's intent is to raise awareness about the contribution bicycling and walking can make to our transportation system with increased investment.
