Critical Issues Draft—Planning
Lead: Ed Granzow, Elizabeth Harper, Bruce Spear
Current Critical Issues in Transportation, as identified in the recent TRB flier by the same name, present ever more difficult challenges for transportation planners who are charged with envisioning, planning, and developing systems that address all of these issues, while remaining realistically attainable. The vision of the Spatial Data and Information Systems Committee is to enable planners to effectively utilize the rapidly growing wealth of geo-spatial data and information technologies in order to better adddress these critical transportation issues.
Planning tools and methods must be developed and enhanced with the primary objective of addressing the Critical Transportation Issues. To that end, the Planning/Modeling vision for the Spatial Data and Information Systems Committee is to support spatial data research with the following objectives:
1. Develop tools and methods that can help to effectively prioritize future transportation investments; weighing future safety, environmental integrity, aging infrastructure investments, and equity considerations.
2. Enhance financial planning through demand-based revenue forecasting.
3. Improve congestion management through better understanding of the relationships between land use, transportation infrastructure, and traffic operations .
4. Improve public involvement and equity considerations through interactive visualization tools
5. Improve emergency response through evacuation planning.
Topics of Interest to the Committee
1. Develop methods for enhancing public involvement in the planning process using GIS technology for visualization and interactive scenario planning.
2. Identify and resolve the pitfalls of using maps to visualize travel demand and environmental impacts of alternative modes and alignments.
3. Test the feasibility of interactive, map-based scenario planning.
4. Test the feasibility of forecasting safety implications of future plan scenarios.
5. Develop methods to improve the planner’s ability to analyze activity-based and tour-based spatial relationships through interactive map-based tools.
6. Integrate various planning models through their spatial components to enable a clearer understanding of relationships between land use, travel demand and traffic operations.
7. Identify methods for streamlining spatial data capture and integration. This might include such things as improvements to geocoding methods, improved links between models and parcel level data, improved links between local land use data and census geography, or dynamic links between planning model data and various sources of roadway and transit data.
8. Develop performance measures and methods for visualization of equity impacts in transportation planning forecasts.
9. Identify positional accuracy requirements for spatial data that supports transportation planning applications.
10. Identify the additional requirements to create transportation networks from spatial data, including positional accuracy, network topology, and supplemental attributes, and develop procedures to facilitate this process.
11. Develop efficient methods for extracting planning model data from remotely sensed imagery.
12. Develop efficient methods for mining the enormous amounts of traffic monitoring data that are becoming available to validate current planning models and to better understand the phenomenon of traffic congestion.
