This document discusses methods for measuring progress towards goals for increasing cycling rates. It outlines goals set by various cities and countries to increase the modal share of cycling. Household travel surveys are identified as an essential data source for understanding transport demand, monitoring progress towards goals, and informing strategic planning. The document describes a household survey conducted in Dresden, Germany, which collects data on trips made by residents over a single reporting day. It notes some potential errors in travel surveys and also discusses other data sources like traffic counts. A variety of options for implementing surveys are presented.

Goals for cycling
• National Cycling Strategy: “Increase of the modal
share of all trips from 10 % in 2012 to 15 % in 2020”
• Leipzig: “The environmentally friendly modes shall
increase from 60 % to 70 % in 2025 (bike: 14 %  20
%)
• Berlin: “Noticeable increase of the modal split of
cycling within the city limits”
• Munich: 17 % modal split of cycling by 2015; result:
17,4 %
