I demonstrate that correctly accounting for spatial diffusion and aggregation weights is important for accurately measuring the inequality of access to consumption amenities. The question wording in the 2001 NHTS (see Table 9) should suffice. The model can be disciplined by the empirical patterns of people's time use interacting with the amenities. 2009 NHTS Household File - Public Use Codebook, Version 2.1 B-5. I present a model of amenity choice that provides the micro-foundation for accounting for spatial diffusion and aggregation weights. Second, to evaluate how much the access to consumption amenities contributes to the overall value of local amenity profiles, researchers must identify the proper aggregation weights. This is an extract of the official NHTS data ( which only contains survey responses from Chicago. Schedule for morning commute from National Household Travel Survey (NHTS). #Nhts codebook driverFirst, because consumption amenities, such as restaurants, often benefit residents living beyond the immediate vicinity of the amenities, researchers must account for how the amenity benefits diffuse through space. At each time step, we also have the link (road segment) ID, driver ID, and vehicle speed. 2001 NHTS Add - On Program : Final Report and Data Codebook. However, quantifying the inequality of access to consumption amenities is often faced with two challenges. Sources : Calculations based on data from 2001 NHTS national sample and Kentucky add - on. Access to consumption amenities, in particular, is often highlighted as an important driver of local amenity profile. led to increasing inequality of amenity access. Existing studies show that the rising spatial segregation between skill groups in the U.S.
