Trip generation rates are usually assigned to various specific land uses.
Surveys are undertaken by either manual observation or data logger technique for determination of generation rates at specific land uses.
These surveys can range from single small stores to very large regional shopping centers.
The basic form of this survey type is the recording of mere count data ingressing and/or egressing a land use.
Land use surveys may entail more complex interview techniques to determine mode choice and stated preferences including parking proximity and trip purpose.
