Evaluating Locational Preference of Urban Activities with the Time-Dependent Accessibility Using Integrated Spatial...

Area of Science:

• Urban Planning
• Transportation Geography
• Spatial Economics

Background:

• Accessibility is crucial for sustainable transportation and quality of life, influenced by land use and infrastructure.
• Traditional urban planning uses static accessibility measures, potentially overlooking dynamic travel conditions.
• Understanding location choice behavior is key to shaping urban forms and land use patterns.

Purpose of the Study:

• To investigate the relationship between dynamic, Time-Dependent Accessibility (TDA) and the location choice behavior of urban activities.
• To analyze the impact of TDA on household and commercial location decisions in Wuhan, China.
• To compare the influence of dynamic TDA versus static accessibility in urban transport planning.

Main Methods:

• Development of Integrated Spatial Economic (ISE) models, specifically PECAS (Production, Exchange, Consumption, Allocation, System) models.
• Application of ISE models to study the impact of dynamic/disaggregate short-term TDA on urban activities.
• Analysis of household and commercial location choices in relation to TDA in Wuhan.

Main Results:

• Urban households in Wuhan's downtown are sensitive to TDA to employment centers, particularly during morning peak hours.
• Commercial services tend to favor locations with high accessibility during off-peak times.
• ISE models demonstrated the distinct impacts of dynamic TDA on different urban activities.

Conclusions:

• Dynamic, short-term TDA is essential for daily urban activities and should be prioritized in urban planning.
• Zoning and facility allocation should consider TDA to better align with actual location choice behaviors.
• Shifting from static to dynamic accessibility measures can enhance the effectiveness of urban transport planning.
