Smooth movement is an essential function and an indicator of a healthy city. Cities being engines of growth, congestion is a real cancer for the country’s economy. In this sense, linking travel habits and the increase in the level of congestion in a city is very important. The objective of this work is to diagnose, using a statistical approach, the dynamics of urban mobility influenced by the traffic congestion situation in the city of Douala. For this, the study focuses on two aspects; the first aspect concerns the multivariate descriptive analysis of motorists’ travel habits. The methods used involve first submitting surveys to motorists in vehicle technical inspection centers and processing the data in IBM SPSS statistical software. Follow-up of the analysis of the correlation between the congestion level and some required solutions. The second aspect focuses on the principal component analysis (PCA) that is performed. The determination of Kaiser-Meyer-Olkin (KMO) indices, the Bartlett significances, and the Pearson correlation coefficients are also done. The results show that the travel habits of motorists create a massive use of roads at certain specific time slots, in addition to extra-municipal trips mainly oriented towards the city center and the administrative district due to the monocentric situation of the city, which contributes to the increase in the level of congestion in the city. The correlation shows that there is significance between the level of congestion and the solutions considered, but this correlation is more or less moderate, which shows that the solutions considered can be used in the short term to alleviate congestion in the city.

Energy-optimizing machine learning-driven smart traffic control system for urban mobility and the implications for insurance and risk management

Heavy traffic during peak hours, such as early mornings and late evenings, is a significant cause of delays for commuters. To address this issue, the prototype of a dual smart traffic light control system is constructed, capable of dynamically adjusting traffic signal duration based on real-time vehicle density at intersections, as well as the brightness of the streetlights. The system uses a pre-trained Haar Cascade machine learning classifier model to detect and count vehicles through a live video feed. Detected cars are highlighted with red squares, and their count is extracted. The vehicle data is then transmitted to an Arduino microcontroller via serial communication, facilitated by the pySerial library. The Arduino processes this information and adjusts the timing of the traffic lights accordingly, optimizing traffic flow based on current road conditions. A novel approach involves optimizing energy usage through real-time data integration with the power grid. Street lighting is then dynamically adjusted at night times—brightening during high-traffic periods and dimming during low-traffic times. The brightness levels are set at 30%, 50%, 75%, and 100% based on the number of cars detected, with above 50% indicating the presence of cars. This adaptive control enhances energy efficiency by reducing energy consumption while maintaining road safety. The simulated and experimental results are provided. The former demonstrated a lower accuracy compared to the latter, particularly during the transition to the green light, across all traffic density levels. Additionally, the simulation was only capable of representing discrete lamp brightness levels of 0%, 50%, and 100%, in contrast to the experimental results, which showed a clear differentiation between 50%, 75%, and 100% brightness levels. Details of the model limitations are outlined with proposed solutions. The implications of the optimized system for auto insurance, liability coverage, and risk management are explored. These are areas that are rarely addressed in current research.

Information System and Smart City, Vol.4, No.1, 2024;

Urban traffic poses persistent challenges, necessitating innovative approaches for effective traffic flow analysis and management. This research adopts a data-driven methodology, employing different algorithms such as K-Means clustering, multiple linear regression to analyse real-world traffic flow. The study utilizes road traffic data collected over seven days, spanning seven hours each day, comprising traffic count, vehicle speed, and categorization by vehicle type. Through rigorous data preprocessing and K-Means clustering, the research identifies distinct traffic clusters, revealing patterns beyond average counts and speeds. Notably, the differentiation of vehicle types within clusters provides nuanced insights into transport mode interactions. The findings contribute to the traffic flow analysis field and offer practical implications for informed urban traffic management strategies. Understanding traffic dynamics aids in developing effective congestion mitigation measures. The study concludes by highlighting potential areas for future research and improvements in optimizing traffic dynamics, emphasizing the importance of data-driven approaches in addressing urban traffic challenges.

Study on traffic efficiency of driver groups at different green light time based on entropy change model

by Xiaojuan Li, Xinliang Guo, Jingwen Zhu, Aijuan Li, Yicheng Mao, Zilin Zhang

Information System and Smart City, Vol.4, No.1, 2024;

The difference in psychological behavior when drivers cross the road has a certain impact on the efficiency of crossing the road. On the basis of analyzing the subjective and objective factors of drivers, the entropy change model of green light time is established and verified. The model can simply judge the time when the driver faces different traffic lights, so as to effectively calculate the drivers driving speed, analyze the traffic situation, and improve the traffic efficiency.

WebGIS map for smart city development and decision support system: A case study of Dehradun Smart City, Uttarakhand, India

by Rakesh Kumar

Information System and Smart City, Vol.4, No.1, 2024;

India is one of the countries in the world which has made continuous progress in the technological revolution. The development of Smart Cities has led to a revolution in e-governance and the citizen-centric approach. The Geographical Indicators and Location-based assets can provide quick action and decision-making approaches to City Administrators. All Smart City GIS Layers on a single platform are beneficial for Smart City and Urban Planners and Administrators to find common solutions for retrofitting the environment. The common GIS Layer helps in utility services planning and drainage mapping which allows for the underground laying of all utility pipes and cables. This research is about the mapping of the common GIS Layer of a Smart City of India on a single WebGIS map to its core. The common GIS Layer will help in decision support and quick action redressal in emergency scenarios as well.

Delivering development to the urban poor through slum dwellers association: The case of Bhubaneswar smart city, India

by Sthitapragyan Ray, Sramana Mukherjee

Information System and Smart City, Vol.4, No.1, 2024;

As cities become hubs of technological innovation and drivers of development, they are also faced with the challenges of the mushrooming growth of slums. Exposed to crowded living conditions, unsafe and hazardous surroundings and lacking in basic amenities of housing, water and sanitation, the urban poor live a life of deprivation in these settlements. Smart cities are expected to provide novel solutions to the persistent challenges of slums. This research explores Bhubaneswar Smart City, capital of the eastern Indian state of Odisha with respect to the implementation of the government’s flagship urban renewal program—JAGA Mission (Livable Habitat Mission). The paper examines the contributions of Slum Dwellers Associations created under the JAGA Mission for development of poor neighborhoods in Bhubaneswar Smart City. The study findings reveal that despite their capacity and financial shortfalls and the potential for politicization, these grassroots associations of the urban poor contributed to the slum up-gradation initiatives of the state.
