EXPLORING THE BICYCLE TRANSPORT MODEL
@Herbert_Tiemens Velo-City 2017 CROW-session
WHY DEVELOPING CYCLING MODELING IN NETHERLANDS Lack of data about cyclists ! not well represented in decision making process Cost-/Benefit analysis Cycling taken for granted in existing models (2012 situation)
Take cycling seriously!

GOAL OF MODEL
Rough insight in numbers of utility cyclists Missing link calculation Road/ network improvements
BICYCLE TRANSPORT MODEL
BRUTUS: AGENT BASED MODELING Modeling individuals “Monte Carlo” engine for:
Activities Mode choice Route choice
Sample expanding to whole population

ROUTE CHOICE MODEL
Example
No deterministic value, but reflect route choice of 100 cyclists between A and B

MY QUESTIONS
Other ways to calculate “Bikeability”? Better sources for diary data (privacy!)? Calibration by open source data (countings, GPS-logs, parking data) Peak-hour / Daytime / Evening?
