Editing Route assignment (section)

== Empirical Studies of Route Choice ==
Route assignment models are based at least to some extent on empirical studies of how people choose routes in a [[Transport network|network]]. Such studies are generally focused on a particular [[Transport mode|mode]], and make use of either [[Stated Preference Discrete Choice Modelling|stated preference]] or [[revealed preference]] models.

=== Bicycle ===
[[Cycling|Cyclists]] have been found to prefer designated [[bike lane]]s and avoid steep hills.<ref>{{Cite journal|last1=Hood|first1=Jeffrey|last2=Sall|first2=Elizabeth|last3=Charlton|first3=Billy|date=2011|title=A GPS-based bicycle route choice model for San Francisco, California|journal=Transportation Letters|volume=3|issue=1|pages=63–75|doi=10.3328/TL.2011.03.01.63-75}}</ref>

===Public Transport===
[[Public transport]] has long been considered in the context of route assignment<ref>{{Cite journal|last1=Liu|first1=Yulin|last2=Bunker|first2=Jonathan|last3=Ferreira|first3=Luis|date=2010|title=Transit Users' Route‐Choice Modelling in Transit Assignment: A Review|url=https://eprints.qut.edu.au/38115/1/c38115.pdf|journal=Transport Reviews|volume=30|issue=6|pages=753–769|doi=10.1080/01441641003744261|via=Taylor and Francis Online}}</ref> and many studies have been conducted on transit route choice. Among other factors, transit users attempt to minimize total travel time, time or distance walking, and number of transfers.<ref>{{Cite journal|last1=Janosikova|first1=Ludmila|last2=Slavik|first2=Jiri|last3=Kohani|first3=Michal|date=2014|title=Estimation of a route choice model for urban public transport using smart card data|journal=Transportation Planning and Technology|volume=37|issue=7|pages=638–648|doi=10.1080/03081060.2014.935570}}</ref>
