Project planning is the stage in planning processes at which facility and service alternatives are analyzed in sufficient detail to make firm implementation decisions. Project planning is (1) multimodal (highway and transit); (2) applicable in urban and rural contexts; (3) involves consideration of capital-intensive alternatives; and (4) focuses on corridors or subareas. Two fundamental approaches to demand analysis in project planning are identified as survey-based approaches, and four-step model-based approaches. The four-step model approach has been used most often in urban areas on project-planning studies for major transit or highway capital projects. The survey-based approach is associated primarily with highway and toll-road projects but is also used in operational and short-range transit planning. Key findings of the workshop were that (1) survey-based approaches are becoming more desirable; (2) integrated forecasting approaches are particularly promising; (3) existing forecasting methods handle unconventional alternatives with difficulty; (4) project planning methods should be consistent with systems-planning methods; (5) demand estimates should be expressed as ranges; (6) need for quick-response techniques in project planning is increasing; (7) basic issues must be faced in maintaining urban travel data bases. The planning process must respond adequately to information needs of decision makers, not being just a facility-improvement plan but have information useful to investment and priority-setting processes.
