2 Abstract Highway-based accessibility measures to jobs and labor for the Twin Cities region were previous computed. The objective of the proposed work is to compute the auto accessibility measures (TAZ level) to other destination types such as retail, entertainment, food/restaurant and recreation for the period of 1995, 2000 and The resulting access measures to different destinations will provide a comprehensive evaluation of accessibility in the Twin Cities region, which can help in operational planning and in public involvement activities of transportation agencies to ascertain how investments, transportation strategies, market conditions, and land use policies affect the performance of the transportation-land use system. Introduction Accessibility measures for walking biking and transit to different types of destinations for the entire seven counties of the Twin Cities were computed by Krizek et al. (2009). Highway-based accessibility measures to jobs and labor for the Twin Cities region were also computed by Levinson et al. (2010). A set of cumulative opportunity measures are computed with transportation analysis zones (TAZs) as the unit of analysis for the years 1995, 2000 and Proposed effort will compute the highway accessibility to other destination types at TAZ level. Reclassified destination cateries and specific destinations are listed in Appendix B. Data Process Methodology The data processing is divided in 2 stages. The first step is to aggregate the land use data from block level to TAZ level. The land use data was obtained from previous non-auto mode accessibility measures project (Krizek et al., 2009). Seven destination types (big box, food, clothing, capital, restaurant, entertainment, and recreation) are processed for AM, PM and off-peak hours in 1995, 2000, and Land use data of seven destination types of each year are loaded in a SQL database as inputs. The aggregated results will be created in separate table in the database after executing the taz_opportunity_xxxx.sql script as illustrated in Figure 1. Sample source code of the taz_opportunity_xxxx.sql script is listed in Appendix. Opportunity7_1995 Opportunity7_2000 Opportunity7_2005 Aggregate Land Use Data from Census Block to TAZ Level taz_opportunity_xxxx.sql e.g., Taz_opportunity_2000.sql Figure 1 Aggregate Land Use Data to TAZ Level Opportunity7_taz_1995 Opportunity7_taz_2000 Opportunity7_taz_2005 Highway travel time between TAZ zones for all 3 years were obtain from Levinson et al. (2010). The accessibility computation script (access_year_period_type.sql) was created to process 63 resulting access tables (3 years [95, 00, 05] x 3 periods [AM, PM, OFF peak] x 7 destination types [big box, food, clothing, capital, restaurant, entertainment, recreation] = 63). The processing flowchart is illustrated in Figure 2. 2

3 TAZ to TAZ Auto Travel Time 95, 00, 05 (Auto_TT) Figure 2 Compute Access Measures Results First 20 records of the 2005 PM peak hour access measures to restaurants were listed in Table 1 as an example. Each record indicates number of restaurants a person from a TAZ zone can reach within 10, 20, 30, 40, 50, 60, 90, or 120 ute of travel via auto mode through highway network. For example, a person in TAZ #1 can access 8 restaurants with 10-ute of auto travel while another person in TAZ #10 can reach 15 restaurants within 10-ute of travel. Map of auto accessibility up to 60- through highway network to restaurants in 2005 PM peak hours is shown in Figure 3. Figure 4 illustrates the map of auto accessibility up to 30- through highway network to foods in 2005 off-peak hours. Processed results are compressed in a zip file (auto_access_to7_dests.zip) which will be sent to CTS electronically.
