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 CHOICES

  Gravity model doesn’t apply for cyclists   “Bikeability” of streets, based upon different parameters   Satisfiers   Dissatisfiers

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?
