The cognitive city transport plays a vital role in setting the targets of monetary similarity and aggressiveness, social harmony, and reasonable significant development. As per the principle of urban development and versatility, the urban communities and their formative experts, which are dynamic in their considerations, are supporting neighborhood governments in handling portability issues, which shape basic examples over all subjective and dynamic populated urban areas. Interest for traveler and cargo transport is continually expanding in urban communities and towns, adding to movement clog, contamination, and car crashes. Understanding the movement clog is a typical test for governments and transport experts in all these urban formative specialists. As per them, putting the current versatility inclines on a maintainable cutting-edge way requires an aggregate rejig of urban portability.

Key findings are provided from NCHRP Study 2-21, which examined how urban traffic congestion imposes economic costs within metropolitan areas. Specifically, the study applied data from Chicago and Philadelphia to examine how various producers of economic goods and services are sensitive to congestion, through its impact on business costs, productivity, and output levels. The data analysis showed that sensitivity to traffic congestion varies by industry sector and is attributable to differences in each industry sector's mix of required inputs and hence its reliance on access to skilled labor, access to specialized inputs, and access to a large, transportation-based market area. Statistical analysis models were applied with the local data to demonstrate how congestion effectively shrinks business market areas and reduces the "agglomeration economies" of businesses operating in large urban areas, thus raising production costs. Overall, this research illustrates how it is possible to estimate the economic implications of congestion, an approach that may be applied in the future for benefit-cost analysis of urban congestion-reduction strategies or for development of congestion pricing strategies. The analysis also shows how congestion-reduction strategies can induce additional traffic as a result of economic benefits.

Transit vehicles create special challenges for urban traffic signal control. Signal timing plans are typically designed for the flow of passenger vehicles, but transit vehicles—with frequent stops and uncertain dwell times—may have different flow patterns that fail to match those plans. Transit vehicles stopping on urban streets can also restrict or block other traffic on the road. This situation results in increased overall wait times and delays throughout the system for transit vehicles and other traffic. Transit signal priority (TSP) systems are often used to mitigate some of these issues, primarily by addressing delay to the transit vehicles. However, existing TSP strategies give unconditional priority to transit vehicles, exacerbating quality of service for other modes. In networks for which transit vehicles have significant effects on traffic congestion, particularly urban areas, the use of more-realistic models of transit behavior in adaptive traffic signal control could reduce delay for all modes. Estimating the arrival time of a transit vehicle at an intersection requires an accurate model of dwell times at transit stops. As a first step toward developing a model for predicting bus arrival times, this paper analyzes trends in automatic vehicle location data collected over 2 years and allows several inferences to be drawn about the statistical nature of dwell times, particularly for use in real-time control and TSP. On the basis of this trend analysis, the authors argue that an effective predictive dwell time distribution model must treat independent variables as random or stochastic regressors.

Like many countries in sub-Saharan Africa, Ghana has witnessed an increase in the use of motorcycles for both commercial transport and private transport of people and goods. The rapid rise in commercial motorcycle activities has been attributed to the problem of urban traffic congestion and the general lack of reliable and affordable public transport in rural areas. This study investigates and compares factors that are associated with motorcycle crash injury outcomes in rural and urban areas of Ghana. This comparison is particularly important because the commercial use of motorcycles and their rapid growth in urban areas are a new phenomenon, in contrast to rural areas where people have long relied on motorcycles for their transportation needs. Preliminary analysis of the crash data revealed that more of the rural area crashes occurred under dark and unlit roadway conditions, while urban areas recorded more intersection-related crashes. Additionally, it was found that more pedestrian collisions happened in urban areas, while head-on collisions happened more in rural areas. The model estimation results show that collisions with a pedestrian, run-off-road, and collisions that occur under dark and unlit roadway conditions were more likely to result in fatal injury. Findings from this study are expected to help in crafting and targeting appropriate countermeasures to effectively reduce the occurrence and severity of motorcycle crashes throughout the country and, indeed, sub-Saharan Africa.

Organization Models

This paper presents a self-organizing model to design effective traffic signaling strategies in order to reduce traffic congestion in urban areas. The proposed traffic signaling system is based on a pattern model of self-organization, i.e., digital infochemicals (DIs), which are analogous to chemical substances that convey information between interactive elements mediated via the environment. In the context of traffic systems, the DIs refer to information generated by vehicles and dissipated by the urban transportation infrastructure. Based on the exploratory analysis with one single intersection, we demonstrate that the DI-based strategy performs significantly better than both the fixed and trigger-based scheduling strategies in terms of queue length and waiting time under both fixed and dynamic traffic demands.

AbstractThe development of urbanization and urbanism in Iran has created a wide socioeconomic gap in urban areas. Rapid population growth along with the lack of socioeconomic growth programs and urban development strategies have deteriorated unemployment, inflation, housing price, traffic congestion, and marginalization in cities, particularly in metropolises of Iran. This paper, using a descriptive-analytic research method and a meta-analysis technique, addresses the urbanization and urbanism changes in Iran. Using GIS technique and CV formula, the spatial distribution of urbanization and its rapid growth in Iran are depicted. The research data was derived from a systematic review of documents and techniques over 40 years. The results of the study demonstrated that Iranian cities have undergone an unsustainable growth trend and urbanization has overtaken urbanism. Over the past 4 decades, cities have been struggling with rapid growth and development. In this regard, development-oriented governments can play a significant role in tackling growth and urbanization problems. These problems are especially evident in the socio-economic, urban planning and urban ecology. The rapid growth of urbanization (74% in 2016) has resulted in the emergence of metropolitan areas in an unstable process. Also, in metropolitan areas of Iran, environmental and ecological threats, rural–urban migration and marginalization have posed serious national–regional and local challenges. The structural–functional reforms in Iran, along with skeletal–spatial and socio-economic changes in cities, have given rise to a new social class (low-income people), which is characterized with non-formal businesses and informal settlements in the outskirts of cities, especially metropolitan areas. This has prompted unsustainability in main indicators of urban development such as security, building density, environmental threats, and centralization, among other things. This analysis is based on indicators such as density and centralization, informal settlement, and urban security.

Small cities and towns in Indonesia have experienced a significant development during the period of 2000-2010. However, the development of small cities and towns has not been in line with the way the urban areas are governed and managed. There is a tendency that the governments pay a little attention to the governance of smaller urban areas, especially those which do not municipal status or the urban areas which is part of regency administrative boundary. This research analyzes the governance and planning of small towns in Central Java taken four small towns in Joglosemar region (Yogyakarta-Surakarta-Semarang). The research applied some qualitative methods combining document analysis, interview and regulation analysis. It is found that there is a significant gap between the urban development and its planning and governance. Urban development policies seem to be lacking in providing guidelines to drive the development of the small towns so that they can perform their functions within their respective regional urban system as well as solve their internal problems. The governance has mostly relied on the role of local government despite continuing lack of institutional capacity in managing urban development.

Public transport transforms urban communities and the lives of citizens living in them by stimulating economic growth, promoting sustainable lifestyles and providing a greater quality of life. Globally, the healthiest cities have one thing in common, a public and active transport network that does not depend on each person owning a personal motorised vehicle. Growing dependence on the automobile has created a multitude of problems, some of which public transport can help solve. Adverse social, environmental and health effects related to automobile emissions and car-dependency suggest that using public transport will result in a decrease in an individual’s carbon footprint, will lessen overall CO2 emissions, and will help to ease urban traffic congestion as well as encourage more effective and efficient land use. With many urban areas experiencing ongoing traffic problems, it is acknowledged that any sustainable long-term solution must entail a significant public transport element. The aim of this research study, conducted in November and December 2017, was to obtain essential baseline information on service user satisfaction levels with the existing public bus services in Galway City, Ireland. By measuring levels of satisfaction, it is possible to build our overall knowledge of the public transport network and thus identify improvements in the service that would lead to an increase in bus passenger numbers and result in reductions in the amount of cars on the roads. Results suggest deficiencies in public transport infrastructure, such as Dedicated Bus Lanes, and the lack of attention to customer services are hindering improvements in the public bus service.

The dynamic development of urban areas poses increasingly more challenges for the provision of transport services for the population. The concentration of the economic potential and population in the metropolitan areas results in the occurrence of large transport needs, and when these needs are met at the same time, the phenomenon of congestion occurs. The purpose of the article is to research the relationship between various factors contributing to congestion in urban traffic and the level of congestion in Polish cities. The authors have used statistical methods such as correlation and regression analysis. The research has shown that the most statistically significant relationships have occurred in the case of the number of business entities and the number of passenger cars. It can be concluded that the demand side factors are more important in Polish cities than the supply side factors or perhaps the current transport policy is ineffective. When effectively applied, transport policy instruments can play a special role. These instruments can contribute to reducing congestion in various ways, i.e. by implementing various sub-objectives, which include reducing the need to travel, reducing the use of passenger cars, improving the functioning of public transport and use of the infrastructure. The results of this study can be useful for transport policy makers at central, regional and local levels.
