| dc.description.abstract | The equilibrium analysis of trip assignment, the contemporary approach, requires individual level origin-destination (O-D) trip surveys that are cost intensive and time consuming. On the other hand, the axial analysis of space syntax, an alternative approach, is less cost intensive and time efficient, but it does not estimate vehicular travel demands with accuracy for a grid-type road layout. This dissertation research integrates both approaches and proposes a new vehicular travel demand model: unit segment analysis. Using the road layouts of a small residential neighborhood and then a typical North American urban settlement, this research shows that unit segment analysis estimates vehicular travel demands with higher accuracy than both equilibrium analysis and axial analysis for the city of Lubbock where road layout is gridded. The findings of this research suggest that along with travel times of O-D routes, flow characteristics of routes also influence the trip makers’ decision of route choice and consequently impact vehicular travel demands of settlement roads. This study discusses several other factors, like land-use influence and edge effect that influence an area's traffic flow, and it delineates a methodology to address these parameters into the proposed unit segment analysis. This research contributes to the planning field by developing a robust planning tool that will guide planners in justifying their planning decisions with data-based evidence in designing transportation policies for infrastructure developments of urban settlements, including development of evacuation plans for emergencies. | |
