- Multifaceted Analysis of Multiple Vehicle Collisions on Motorways
Abstract: Publication year: 2023Source: International Journal of Traffic and Transportation Engineering, Volume 12, Number 2Anastasios MouratidisMultiple-Vehicle Collisions (MVC) are chain-reaction road accidents involving three or more vehicles. They are a rare type of severe traffic incidents and, usually, occur on major roads, such as, motorways and national arteries, under high traffic volume. Successive vehicle crashes, on these major transport links, produce not only road closures, but also, very often, injuries and fatalities. Due to their nature, severity and extent, multiple-vehicle collisions are one of the most disastrous and fatal types of road accidents. The hereby research focuses on the features of severe multiple-vehicle collisions and attempts to identify the most recurring causes of these accidents. Low visibility, pavement slipperiness and inconsiderate driving are recognized as common major causes, while tailgating, high speed and road works are also pointed out as factors susceptible to generate multiple crashes. Based on data available from journal reports, a concise interpretation of the causes of these MVC’s was conducted and is hereby presented. Moreover, a statistical analysis on the distribution of multiple vehicle collisions by crash cause and impact has also been carried out, meant to explore and to identify the most adverse conditions for traffic safety. The research concludes with a list of proposed proactive measures, adequate to motorways, which may prove to be beneficial in the case of uncertain safety conditions, as well as, with remedies to be applied after an incident, to alleviate a stressful situation and to mitigate the risk for secondary crashes.
- Use of a Social Vulnerability Index in Investigating Transit Deserts in
Alabama
Abstract: Publication year: 2023Source: International Journal of Traffic and Transportation Engineering, Volume 12, Number 1Mehrnaz Doustmohammadi, Eric Merschman, Michael Anderson, Sharareh BiglariAccurately predicting the true demand of transit is one of the most challenging and crucial matters that various departments of transportation are attempting to solve. One of the tools for predicting the demand and creating the proper infrastructures and facilities, is using a social vulnerability index (SVI). This index is developed using the vulnerability demographics of old age, poverty, vehicle ownership, crowded housing, and disability. The value of estimating demand using social vulnerability is to attempt to focus on individuals who are more likely to rely on transit for their means of transportation, as such, socially vulnerable demographics which limit an individual’s ability to traverse the network may be used by a decision-maker when attempting to allocate resources or investment towards underrepresented areas. The index is then used to identify potential transit deserts or areas in which demand exists but has no transit service. In this study, the index uses U.S. Census data to identify the most vulnerable counties for the state of Alabama. The areas designated as most vulnerable are areas with historic economic deficiency and tend to be more rural counties. Future research is required however to relate transit ridership to the vulnerability attributes selected. To this end, cooperation with state transit agencies is required to have a more in-depth understanding of the results.
- Prediction of Electric Vehicle Charging Stations Distribution in Kuwait
Abstract: Publication year: 2023Source: International Journal of Traffic and Transportation Engineering, Volume 12, Number 1Alrajhi J. M., Alardhi M., Alhaifi K. K., Alkhulaifi K., Khalfan A., Alhaifi N. A., Alazemi J.Kuwait has an area of 17,818 sq. km and a population of 4.3 million residents most of whom live in its urban centers, with a dry desert climate and poor agricultural cover. Demand for electric vehicles (EVs) in Kuwait is currently low. Between January and October 2021, only 88 EVs were sold in Kuwait. However, EV sales in Kuwait are expected to grow exponentially in the future. More than 50% of drivers in the country have positive attitudes toward EVs. In addition, Kuwait aims to reduce greenhouse gas (GHG) emissions and build a sustainable economy. Comparative statistical data reveals that, in 2021, Trends in oil-dependent economies related to EV adoption reflect the future of the EV market in Kuwait. The multi-criteria decision analysis approach is the method Kuwait is currently applying to optimize the infrastructure and distribution of electric vehicle charging stations (EVCS). It is an analytical hierarchy process (AHP) for establishing the sites of EVCS and enhancing their spatial distribution. Kuwait will likely integrate AHP algorithms with the geographical information system (GIS) to optimize the distribution of EV chargers, including within on-road parking spaces and off-road charging sites. Its EVCS network could include level 1-3 charging modes. Furthermore, Kuwait could leverage an EVCS management system to enhance the efficiency of EVCS operations. This research is aimed at predicting the distribution of electric vehicle charging stations in Kuwait.
- The Future and the Effect of Using Electric Vehicles in Kuwait and UAE
Abstract: Publication year: 2023Source: International Journal of Traffic and Transportation Engineering, Volume 12, Number 1Alhaifi N. A., Alazemi J., Alrajhi J. M., Alhaifi K. K., Alardhi M., Alkhulaifi K., Ahmed KhalfanThis research is to review records and archival data to determine the status of electric vehicles (EVs) and their impact in Kuwait, the United Arab Emirates (UAE), and other developing countries. According to the findings, Kuwait lags behind the UAE in manufacturing and using EVs because it has yet to establish the necessary infrastructure, such as charging stations and manufacturing centers. However, it has laid programs to steer the manufacturing of EVs to gain the positive impacts of these vehicles, such as reduced emission of greenhouse gases (GHGs), reduced energy and maintenance costs, and increased efficiency. Indeed, EVs will be the main driver of the zero-emission goal, especially considering that Kuwait and other countries in the Gulf Cooperation Council (GCC) rely heavily on petroleum products in transportation.
- Using the Minimize Distance Method to Find the Best Compromise Solution of
Multi-objective Transportation Problem with Case Study
Abstract: Publication year: 2022Source: International Journal of Traffic and Transportation Engineering, Volume 11, Number 2Mohsen Alardhi, Hilal A. Abdelwali, Ahmad M. Khalfan, Mohamed H. AbdelatiThe classical transportation problem aims at finding the optimal distribution of a certain product from different sources to different destinations. The objective of this optimal distribution could be minimizing the total transportation cost, time, distance or any other related single objective. In real world applications there are more than one objective function to be studied while transporting products for companies. Therefore, the multi-objective techniques should be implemented on such problems. The minimize distance method is a proofed method to find the best compromise solution of multi-objective linear programming problems. In this paper we applied the minimize distance method on a real two objective transportation problem. Two LINGO codes are prepared to find the best compromise solution and more other efficient solutions to be ready for the decision maker to choose from. The model, the solution algorithm, the collected data and the output results are included in this paper as a case study.

- Effect of Traffic Congestion on Productivity in Ghana: Evidence from
Atwimah-Nwabiagya Municipality, Ashanti Region-Ghana
Abstract: Publication year: 2022Source: International Journal of Traffic and Transportation Engineering, Volume 11, Number 1Prince Owusu-Ansah, Abena Agyeiwaa Obiri-Yeboah, A. R. Abdul-Aziz, Emmanuel Kwesi Nyantakyi, Saviour Kwame Woangbah, Jack Nti Asamoah, Nana Osei Bonsu Ackerson, Ebenezer AduseiImplementation of decentralization policies by successive governments in Ghana has contributed to an upsurge in economic activities in all district capitals and major cities leading to increased productivity, standard of living and social life. Undoubtedly, positive economic growth is directly related to road traffic congestion, a menace in district capitals and metropolitan areas in Ghana. To this end, the study examined the effects of traffic congestion on productivity and its related impacts on inhabitants of Atwima Nwabiagya municipality in the Ashanti Region. Data collected from an online structured questionnaire sourced and completed by 160 respondents were obtained through cluster and systemic random sampling from the municipality and was analysed in SPSS v. 26 and R v. 4.0.4. The study found that the people of Atwima Nwabiagya are tolerant with congestion and that on-going construction, faulty traffic signals, poor driver attitude, unauthorized parking, vehicle breakdown, volume of traffic, and poor road design are significantly contributing factors affecting productivity in the Atwima Nwabiagya municipality rather than the poor pedestrian attitude and provision of inadequate routes. The authors recommend the provision of adequate parking facilities with dedicated designated bus-stops as a measure to ease the congestion menace and suggests for further study, an investigation into why traffic congestion must be tolerated.

Alhaifi, Mohammad AlbannaqOwing to consumer demand and government initiatives focused on combating climate change the electric vehicles adoption is expanding around the globe. In 2030, more than 100 million such vehicles are expected to be on the road, compared to about seven million currently. There is obviously an electric future in transport, as a result there will be a natural increase of accidents involving electric vehicles & various risks associated with these vehicles. Currently there are not many cases of accidents therefore the rescue services & preparedness to deal with such accidents are still partially open point for discussion. This paper presents the potential risk exposures and need for preparedness to deal with these risks & road accidents related to Electric vehicles in Kuwait.
- Prediction of Road Accidents Trend in Tanzania Using ARIMA Model: The Road
Safety Implication by 2021-2030
Abstract: Publication year: 2022Source: International Journal of Traffic and Transportation Engineering, Volume 11, Number 1Vitalis Agati Ndume, Edwin C. Rutalebwa, Angela-Aida K. RunyoroThe purpose of this study is to predict the road accidents and justify whether Tanzania can reach the target of the global Second Decade of Action for Road Safety 2021-2030 calls. The study applied time-series modeling to determine and predict road traffic accidents patterns in the selected regions in Tanzania. Regions selection was based on those with the high rate of accidents. The secondary data obtained from Tanzania Road Safety Squad were used in analysis. Data were then loaded on R- packages for analysis. A time-series analysis using ARIMA Model was conducted to characterize and predict the frequency of road traffic accidents that lead to injury. The traffic accidents were categorized into four separate groups; these are accidents related to the car driver's behavior, motorcyclists, bicyclists and pedestrian. ARIMA model was used to model time series in each group from 2013 to 2021 and to predict the accidents up to 10 years later (2030). The analysis was carried out using R-4.1.1 statistical software package. The main contribution of our study in the field of road safety is estimation of number of death that can occur due to road accidents by 2030 which is estimated to decrease by 97%.
- Assessment of Road Traffic Noise in the Greater Kampala Metropolitan Area,
Case Study of Namulanda-Kisubi Stretch, Entebbe Road
Abstract: Publication year: 2021Source: International Journal of Traffic and Transportation Engineering, Volume 10, Number 2Mubiru Joel, Angurini Manaseh, Kirabo Enock, Nandugwa HarrietRoad traffic noise is one of the environmental pollutants that people in Uganda tend to ignore. This maybe because they tend to grow fond of it as a result of its continuous prevalence. Some even go to the extent of purchasing plots of land in close proximity to highways and other roads for residential purposes for ease of access to the Central Business District. This paper however, entails an assessment of road traffic noise particularly in the Greater Kampala Metropolitan Area and its impacts to the people settling or working in close proximity to the road network. It shows the main impacts of the traffic noise according to respondents’ questionnaire surveys, the greatest of which was found to be sleep disturbance (with over 40% of the respondents in concurrence). The magnitude to which the prevailing traffic noise exceeded the noise criteria in Uganda was undertaken by carrying out noise measurement procedures using the sound level metre which gave results between 19-33dB (A) in excess of the criteria. Its root causes and the factors affecting the road traffic noise are exhaustively brought to light in this document. This gives rise to how best this menace can be wiped off the face of Uganda by proposing effective mitigation measures through the design of suitable noise barriers and introduction of autonomous vehicles. This only means that the government of Uganda should take the issue of traffic as a serious one and should not be left out in urban planning. However, this can only happen after traffic noise is fully assessed hence the reason for this documentation.
