Residential Geolocation of Households in a Large-Scale Activity-based Microsimulation Model and Development of a High Definition Spatial Distribution of Vehicle Miles Traveled

摘要

This paper presents a methodology to distribute the Traffic Analysis Zone (TAZ) levelsynthesized households and their members to parcels according to the household andparcel attributes. Three Multinomial Logit (MNL) models are estimated to represent theresidence location association of households and land parcels, one each for single person,two persons or more without children, and two persons or more with children householdtypes. The estimated models are then used in an algorithm that assigns households tolocations in the Los Angeles County. Daily Vehicle Miles Traveled (VMT) of eachhousehold are assigned in this way to the parcel the household is assigned using thealgorithm. The method illustrated here shows the feasibility of doing this assignmentusing millions of parcels and households. It also shows that the results are reasonableand that it is possible to estimate VMT at specific locations and for spatially disaggregatejurisdictions, enabling the assessment of VMT responsibility and associated policies atvery fine levels of resolution. In addition, our findings and related maps challenge theclaim that central city residents travel less miles and suburban residents travel more.
