Chart shows changes in emissions relative to baseline. First row confirms: Technology penetration and fuel type help somewhat, but dividends come from fleet renewal, offset by VMT growth Scenario HC CO NOx CO2 Present: Alternative -7.7 -13.8 -3.1 -3.6 Future, No Growth: Baseline -82.0 -71.9 -91.5 -12.8 Future, No Growth: Alternative -82.7 -75.8 -92.1 -15.3 Future, Growth: Baseline -71.4 -58.0 -87.0 34.4 Future, Growth: Alternative -72.3 -63.6 -87.9 29.3 Form Multi-dimensional Policy-relevant Trend-revealing Function Residents Jobs Investments * * 规划的实施应包含比落实各种公共设施更多的内容。 ? * 将目标细化、落实到可以实施的行动： 例如，纽约市关于管理、提高水质量的目标，就制定了十项政策行动计划； * “绿色纽约“有150多项行动计划 如何应用这些研究成果？ 城市空间管理的范畴—公共政策 New directions 新方向—更跨领域 Market forces 市场因素 Taxation Land use regulation Infrastructure 各种公共政策 Outcome Evaluation 城市空间管理是否达到目标 Urban Development 城市空间 Observation Evaluation 了解城市空间 (1) (2) (3) (4) Conclusions 结语 Empirically, through different methods, confirmed relevance of spatial development 城市空间管理的相关性 Comprehensiveness of urban management 城市空间管理的广泛性 Thank you very much! * Form Multi-dimensional Policy-relevant Trend-revealing Function Residents Jobs Investments * Form Multi-dimensional Policy-relevant Trend-revealing Function Residents Jobs Investments * Backward mapping * * Remove parcels less than 2 acres (subdivision ordinance) Remove parcels under public ownership, floodplain, etc. At least 0.5 of “successor” parcels under residential use at end of study period Highland Meadows parcel before (2001) and after (2002) subdivision. 18 acres, 72 lots Used Python scripting to automate process according to following algorithm: Step 1: Loop through each parcel in the sample at the current time period and using the unique parcel identifier, select the corresponding parcel identifier from the subsequent time period shapefile. Step 2: If the total acreage of the parcel changed by more than 10% (to account for rounding error and small variations in the topology of the polygons th
