Exploratory Spatial Data Analysis of Traffic Forecasting: A Case Study

Transportation planning has historically relied on statistical models to analyze travel patterns across space and time. Recently, an urgency has developed in the United States to address outdated policies and approaches to infrastructure planning, design, and construction. Policymakers at the federal, state, and local levels are expressing greater interest in promoting and funding sustainable transportation infrastructure systems to reduce the damaging effects of pollutive emissions. Consequently, there is a growing trend of local agencies transitioning away from the traditional level-of-service measures to vehicle miles of travel (VMT) measures. However, planners are finding it difficult to leverage their investments in their regional travel demand network models and datasets in the transition. This paper evaluates the applicability of VMT forecasting and impact assessment using the current travel demand model for Dane County, Wisconsin. The main finding is that exploratory spatial data analysis of the derived data uncovered statistically significant spatial relationships and interactions that planners cannot sufficiently visualize using other methods. Planners can apply these techniques to identify places where focused VMT remediation measures for sustainable networks and environments can be most cost-effective.

Implementing Design and Operational Measures for Sustainable Mobility: Lessons from Zurich

Increasing mobility and urbanization is important for economic prosperity but leads to higher urban traffic congestion, which is associated with many negative externalities. Therefore, cities are in need of integrative solutions that reduce their transportation network’s spatial and environmental footprint, while maintaining the highest transportation efficiency possible. Focusing on a nontraditional and more sustainable cycle of urban transportation, this paper covers an integrated perspective by describing a combination of individual design and operational measures. To do so, a case study of the city of Zurich is presented, which consistently ranks highly across different indicators, from smart city to sustainability. This paper is therefore a qualitative review of different measures that the city has implemented to become more sustainable. The measures are compared with indicators from the existing literature and classify them into three clusters: (i) measures discouraging private motorized transport, (ii) measures encouraging public transport, and (iii) measures encouraging human-powered mobility. The discussion thereof allows us to integrate the different measures to define a sustainable transportation cycle, which potentially serves as a best-practice example.

A Priority in Land Supply for Sustainable Transportation of Chinese Cities: An Empirical Study from Perception, Discrimination, Linkage to Decision

With the rapid development of China’s economy, alleviating the shortage of land resources has become a significant challenge. Transportation infrastructure is a channel connecting cities, which carries the flow of population and material circulation. The efficient allocation of land used for transportation is closely related to production and life. By investigating the main factors affecting the priority of the supply of land used for transportation, this paper evaluates the transportation condition of all cities in China from five aspects: dominance, dependence, coordination, accessibility, and land demand for transportation. Furthermore, this paper constructs a multi-objective decision support system for land supply, which aims to find out which cities are in urgent need of the supply of land for transportation and what types of transportation infrastructure need to be focused on. The results of this paper show that most of the cities with high land supply priority are non-provincial capital cities and are important growth poles of regional economic development. The construction of a comprehensive transportation system is the short-term goal of these cities. Most cities with low land supply priority are sparsely populated, in good ecological condition, and far away from the core areas of economic development. The preferred transportation mode of these cities is generally land transportation. The main contribution of this paper is to provide a comprehensive decision support system for the land management department to determine land supply priorities and achieve the sustainable use of land.

Assessment Method on United Nation Sustainable Development Goals, Applied for a Sustainable City, with a Focus on Greater Khartoum Services

The first approach for environmentally sustainable development to the global community was introduced in 1992 in the United Nations conference on environment and development, the "Earth Summit", which took place in Rio de Janeiro, Brazil.(genda21). Defining Sustainable development as the one that meets the needs of the present generation without compromising the ability of future generations to meet their own needs. Therefore, the study will focus on the United Nations Sustainable Development Goals UN-SDGs and the making of Sustainable cities. The aim of the research is to propose a framework to transform Greater Khartoum into a Sustainable city and to find out criteria for an Assessment Method that is applicable for Greater Khartoum. Which including providing Safe affordable housing and basic services, Sustainable transportation, Sustainable home settlements in the three towns, protect culture and Natural Heritage, Reduce Waste including water, air and solid waste, public access, Green-space, Support positive economic, social, and environmental links between urban and rural areas, National and local disaster risk reduction strategies, Interlinkages and implications for policy-making In addition, the methodology of the research focuses on defining, identifying, and measuring the indicators and sub-items. The measurement applied through survey and questionnaire. Distributed and distribute to all engineers specialized in architecture, urban, civil, electrical, and mechanical engineers in the three cities (Khartoum-Khartoum North-Omdurman). Finally, the outcomes of the research, applying the criteria of SDGs to evaluate the present situation in sustainable development criteria in Greater Khartoum; most of the indicator record results the research recorded results show that the goals were not achieved in most of the situations, between (20-30) especially in services (Table 1), waste management and open spaces are average (40-49). Will provide valuable recommendations towards improving the future and urban planning and sustainable development for the Capital city.

The Role of Transport in Reverse Distribution Chains

Reverse distribution operations have become significant to the manufacturers in supporting the firms to achieve the circularity of products in the reverse flow chains. There are four main components of the reverse distribution chains; inbound and outbound transportation, collection of returns, centralised returns centres, and recovery process. Transport is essential by reducing the lead time and transportation cost of the used and the recovered products. Therefore, it is pertinent that the manufacturers continue endeavouring for the sustainable transportation process in each of the components to ensure the success of the reverse distribution chains.

TRAVEL MODE CHOICE INTENTION IN REDUCING TRAFFIC CONGESTION IN KAJANG, SELANGOR

The intentions behind a person’s choice of transportation mode is vital information to have in strategic planning for a sustainable transportation system, and is very useful in predicting the behaviours of people. This paper was conducted to identify people's preferences of public transport. Using the Theory of Planned Behaviour (TPB) as the psychological determinant, three main indicators, attitude, subjective norm and perceived behavioural control (PBC), were explored to identify the mode choice of public transportation among the residents of Kajang. The data was obtained through questionnaires by employing a multistage sampling technique, where 348 respondents were approached. Partial Least Square (PLS) analysis showed that attitude was the dominant indicator among residents of Kajang for modes of public transport. This paper will contribute to the advancement of knowledge in the theory of mobility and travel behaviour, as well as act as baseline data for predicting people’s travel behaviour in future mode shift strategies dealing with everyday issues of traffic, such as congestion.
