Positive effects for individuals

and urban societies

Which factors make cities

bicycle friendly?

Hovenring, Eindhoven (Netherlands)

Problem Statement

Many highly frequented institutions (main station,

university etc.) provide adequate bicycle

infrastructure.

Problem Statement

Many cities and regions invest in bicycle infrastructure

in order to increase the modal split.

Problem Statement

Despite these efforts, the potential of the bicycle can

not be used in the most effective way

Lack of connectivity

Poor accessibility

Obstacles

Thus accessibility and safety needs to be taken into

acount in planning for bicycle traffic!
