Summary
Street connectivity influences active transportation (AT), but its duration is more spatially correlated at finer scales. Understanding these built environment factors is key for promoting physical activity.
Area of Science:
- Environmental Science
- Public Health
- Urban Planning
Background:
- Previous studies on built environment and active transportation (AT) often overlook spatial autocorrelation and a combined analysis of AT propensity and duration.
- Understanding these relationships is crucial for improving public health through environmental interventions.
Purpose of the Study:
- To analyze the association between street connectivity measures and both the propensity and duration of active transportation.
- To investigate the spatial autocorrelation of active transportation behaviors.
Main Methods:
- Utilized data from the 2001 California Health Interview Survey in Los Angeles and San Diego Counties.
- Employed principal components analysis for street connectivity measures and multivariate analysis to examine AT propensity and duration.
- Assessed spatial autocorrelation at different geographic scales.
Main Results:
- Two principal components explained 85% of the variance in street connectivity, both positively associated with AT.
- While propensity for AT showed no spatial autocorrelation after controls, AT duration exhibited localized correlation, particularly in San Diego.
- A finer spatial scale (0.6 mile diameter) was more appropriate for explaining variations in connectivity and AT duration.
Conclusions:
- Joint analysis of AT propensity and duration using a geographic approach strengthens built environment studies.
- Findings support the need for longitudinal and experimental designs to evaluate environmental interventions for increasing physical activity.

01:28Design Example: Joints in Concrete Pavements
Concrete pavement joints are essential for maintaining the structural integrity and longevity of pavement by controlling where and how the pavement cracks. These joints can be categorized based on their functions, such as contraction or control joints, construction joints, isolation joints, and expansion joints.
Contraction joints are typically formed by sawing a groove into the concrete shortly after it has hardened. This creates a weakened vertical plane, deliberately encouraging cracking at...

01:41Social Traps
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned more cows, the larger...
01:14Active Transport
Active transport is a critical biological process that allows cells to move solutes against an electrochemical gradient. This process requires direct energy input and is characterized by its selectivity, saturability, and susceptibility to competitive inhibition.
Primary active transporters, like Na+, K+ and -ATPase, directly utilize ATP to move ions across the membrane. These transporters play significant roles in various physiological processes. For instance, Na+, K+ and -ATPase maintain...

01:17Design Example: Alignment of a Road Line Using GIS
The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...
01:29Levels of Use of a GIS
Geographic Information Systems (GIS) operate across three levels of application, each representing an increasing degree of complexity: data management, analysis, and prediction. These levels reflect the expanding functionality and versatility of GIS technology in handling spatial data for diverse purposes.Data ManagementAt its foundational level, GIS serves as a tool for data management, enabling the input, storage, retrieval, and organization of spatial data. This level is often employed in...
01:29Electrical Transport
The electrical transport property of a material is defined by its resistance and conductivity. Resistance is the measure of a material's ability to resist the flow of electric current, while conductivity gauges its ability to allow the current to pass through, depending on the geometry of the measurement cell, such as electrode spacing and area. Conductivity is measured in Siemens (S). There are different types of conductance, including specific conductance, equivalent conductance, and molar...
