Literature review of accessibility measures and models used in land use and transportation planning in last 5 years

Abstract

Since its inception accessibility has undergone various changes in the way it is defined, measured, and modeled. The paper reviews the recent advancements made in the accessibility measures along with the models used in different applications of accessibility related to land use and transportation. The measures of accessibility are grouped under infrastructure-based, location-based, and person-based measures. The paper finds that although the person-based measures are statistically robust and theoretically sound, they are less preferred than the location-based measure in the accessibility measurement. The review finds recent development such as web based mapping and use of location based data; image mapping through convolutional neural networks; and activity-time constraints modeling in the measures of accessibility. Further, the paper reviews literature from the last five years that have used accessibility to study travel mode choices and household location choices and finds the use of three types of modeling framework -Statistical, Neural Network, and Agent Based models. Based on the literature review, this paper suggests the inclusion of environmental sustainability and gender equity in the accessibility measurement framework and a shift towards model synthesis to enhance the model accuracy and to reduce the present complexities in model building.

[Retracted] The English Teaching Methods in the Field of Public Health in Colleges and Universities Based on Artificial Intelligence Technology

“…The deepening of public health awareness is also the optimization direction of the English teaching system in colleges and universities. The cultivation of college students' public health awareness is an important part of the improvement of students' comprehensive quality, and it is also the fundamental requirement for the all-round development of colleges and universities [5,6]. At this stage, the proportion of health education in college English teaching courses is relatively high.…”

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

“…Most of the existing models are as follows: Integrated Model of Residential and Employment Location (IMREL) [ 62 ]; Marcial Echenique and Partners (MEPLAN) [ 24 ]; Transportation and Environment Strategy Impact Simulator (TRESIS) [ 63 ]; Microeconomic Land Use Transportation Model (METROSIM) [ 64 ]; Modelo de Uso de Suelo de Santiago (MUSSA) [ 65 ]; Production, Exchange, Consumption, Allocation, System (PECAS) [ 66 ]; Random-Utility URBAN (RURBAN) [ 67 ]; Transport and Land Use Model Integration Program (TLUMIP) [ 10 ]; Transport and Land Use Model (TRANUS) [ 25 ]; Urban Simulation (URBANSIM) [ 10 ]; and DELTA, which is an abbreviation for different five sub-models. The transition and growth model; location and property market model; employment and status and commuting model; development model; and area quality model (DELTA) [ 1 ] have detailed sub-models for metropolitan land and housing. These models use a multi-industry, multi-regional input–output system to forecast production and consumption positions in the urban area, where households of different types are viewed as labor-producing industries and commodity-consuming ones.…”

“…The TDM calibration was carried out at trip generation, distribution, mode choice, and assignment level. After the TDM was fully calibrated and converged, the time-dependent utility-based accessibility measure was calculated using Equation (1).…”

“…A livable city is one where residents enjoy a healthy lifestyle and economic prosperity. Accessibility is an integral part of livable cities, as it significantly influences the various behaviors of activities within the city, such as travel behavior and home location choice [ 1 ]. The significant impact of accessibility on sustainability and urban economics is widely acknowledged [ 2 ].…”

“…Traditional mobility-based planning tends to evaluate transport system performance primarily based on traffic speed and therefore favors automobile-oriented transport improvement [ 11 ]. On the other hand, accessibility-based planning considers additional impacts and options, including improvements to alternative modes, incentives to change travel behavior, and most importantly, more accessible land use patterns [ 1 , 12 ]. Many current planning practices tend to favor mobility over accessibility and automobile travel over alternative modes [ 13 ].…”
