“…To effectively evaluate the proposed transportation system which is the main objective of this paper, a multimodal transport model was developed using Cube Voyager software licensed to Wuhan university of technology. Wuhan PECAS model developed by Zhong et al [13], was first modified to include the proposed new city. The Wuhan PECAS model was then used to simulate and forecast land-use activities for the proposed new city and these activities were then converted into socioeconomic activities as an input to the transport model.…”

“…The TDMs has also been criticized by several researchers for many disadvantages [11,12]. According to Zhong, et al, [13], the conventional TDMs do not consider changes in the transport system of cities undergoing rapid urbanization. Integrated land-use transport interaction models (ILUTIM) were developed to overcome this drawback.…”

“…However, most ILUTIMs developers still use the four-step travel demand model in their integrated models [14] To reduce the negative externalities from land-use and the transportation system interactions, city authorities are emphasizing evaluating land-use and transportation projects. To this effect, integrated land-use and transport models have become the necessary tool for evaluating land-use and transport projects in most developed and some developing countries [13].…”

The effect of traffic congestion, emission, and road accident on cities that depend solely on motor vehicles make them unsustainable. Increased mobility from rapid urbanization has placed great demand on the transport system of such cities. To meet the increasing demand, modelling travel demand based on the transport network has become a necessity for sustainable urban development. In this study, an advanced transport and land-use modelling framework was developed to evaluate a transport system of a proposed new city. Furthermore, transport (road) network connectivity indices were used to measure the level of connectivity of the transport network. The findings show that the proposed transport system may not support the sustainable urban development of the new city due to the low level of network connectivity. The result further revealed that about 52% of the residents will depend on auto modes of transportation making the new city car-dependent rather than transit-dependent. Specifically, all corridor road links showed a high level of traffic congestion problem. The alternative of building more rails or a bus rapid transit (BRT) system connecting the main and a new city is worth considering when proposing an urban transport system. The advanced transport and land-use modelling framework developed in this study to evaluate the performance of the transportation system could serve as a decision-support system (DSS) towards sustainable planning and development of both old and new cities.

“…Several Land Use Transportation Interaction (LUTI) models have been developed over the past decades for location preference and interactions of urban activities, including the Lowry model, IMREL, MEPLAN, TRESSIS, METROSIM, MUSSA, URBANSIM, REURBAN, TLUMIP, TRANUS, DELTA, and PECAS [41][42][43][44][45][46][47][48][49][50][51]. These models estimate production and Land 2022, 11, 1139 6 of 31 consumption positions in the metropolitan area using a multi-industry, multi-regional input-output system, with households of various types regarded as labor-producing industries and commodity-consuming industries.…”

Accessibility is the ease of reaching opportunities (goods, services, activities, and destinations). Accessibility of desirable locations such as households and commercial locations, is typically scaffolded by land use patterns and transportation infrastructure. It can reflect people’s travel convenience, cities’ viability, sustainability, and mitigate the negative effects on the environment and public safety. Consequently, it is recognized as a fundamental principle in urban sustainable development policies worldwide. In the literature, most of the studies have used a static or partially dynamic approach with a single mode such as a car or public transportation by using conventional models. These “static” models assume that household locations are static and that transportation supply and opportunities for social practice activities are fixed in time and space, which can lead to biased or even misleading assumptions in accessibility models. Therefore, the aim of this study is to evaluate the impact of dynamic spatial accessibility through Mode-Dependent Accessibility (MDA) on the location choice behaviors of urban activities such as households and commercialin the City of Wuhan, China. This study employed the Mode-Dependent Travel Demand Model (M-TDM) to measure the impact of short-term MDA on household and commercial activities for the years 2012 and 2015. Additionally, an integrated spatial economic (ISE) model such as PECAS (Production, Exchange, Consumption, Allocation, System) in order to investigate location preferences of urban activities over space and time. Regarding household and commercial location choice, the ISE modeling results revealed that households and commercial activities are sensitive to MDA, especially using transit. The ISE method predicted that the R2 for household and commercial location choice models was 0.84 to 0.90 for transit-based accessibility, whereas the R2 for logsum-based static models was 0.48 to 0.72. In addition, their findings suggest that highly accessible locations that are well served by auto are more appealing for household and commercial activities. The findings of this study will help urban planners, transportation planners, and policymakers take into account the dynamic nature of short-term MDA when zoning and allocating urban activities and public amenities, instead of using static accessibility.

“…The existence of at least three main categories of integrated models, based on previous LUTI modeling reviews [ 25 , 58 , 60 ], are spatial interaction models, econometric models, and disaggregate microsimulation models. The PECAS model was developed for forecasting and policy analysis at urban and regional levels in Caracas Region in Venezuela [ 68 ].…”

In recent years, accessibility has been considered a vital policy objective in the development of a sustainable transportation system. Accessibility can make a significant contribution to quality of life. The accessibility of desirable locations, such as households and commercial locations, is usually underpinned by land use patterns and transportation infrastructure. The accessibility of different activities is largely determined by the spatial distribution of activities and associated transport networks in a metropolitan area. In order to examine how location choice behaviors of urban activities influence urban forms and land use patterns, accessibility has been used extensively to consider the impact of both the spatial distribution of opportunities (e.g., employment or services) and the transport cost of reaching them. However, in most cases, only those static/aggregate accessibility terms that are represented by the “logsum” of all available transport modes have traditionally been used in urban transport planning and modeling analysis. In this study, according to urban activities, several Integrated Spatial Economic (ISE) models i.e., PECAS (Production, Exchange, Consumption, Allocation, System) models were developed to study the relationship between dynamic, Time-Dependent Accessibility (TDA) and the location choice behavior of urban activities in the City of Wuhan, China. The developed models were then used as tools to investigate the impact of dynamic/disaggregate short-term TDA on location choice behaviors of various urban activities such as households and commercial. Regarding the household location choice, the ISE modeling results revealed that urban households living in the downtown area of the City of Wuhan were sensitive to TDA to employment centers, especially during the morning peak time. In addition, commercial services prefer locations that offer a high level of accessibility during off-peak times. Based on the results of this study, it is recommended that planning exercises, such as the development of zoning and the allocation of urban activities and public facilities, pay more attention to dynamic, short-term TDA, which is essential for urban sectors to carry out daily activities, than their static, composite accessibility counterparts.
