1.0 Introduction
1.1 Background of Study
Traffic congestion has become one of the most pressing challenges in urban areas globally. As cities continue to grow in population and economic activity, the demand for transportation infrastructure increases, often outpacing the development of efficient road networks. This imbalance has led to frequent bottlenecks, reduced traffic flow, and prolonged travel times, negatively impacting the quality of life and the environment. According to a report by the International Transport Forum (2018), traffic congestion costs cities billions of dollars annually due to lost productivity, increased fuel consumption, and environmental degradation.
In recent years, advancements in technology have enabled more accurate data collection methods, such as traffic sensors, GPS tracking, and real-time monitoring systems. These technologies provide vast amounts of data that can be analyzed to gain deeper insights into traffic congestion dynamics. Moreover, Chien, Ding, & Wei, (2021) stated that the use of statistical models, such as regression analysis and machine learning algorithms, has significantly enhanced the ability to predict congestion patterns and identify potential solutions (Chien, Ding, & Wei, 2021).
Traffic Congestion according to Litman (2020) refers to the condition in which the volume of traffic on a road exceeds its capacity, resulting in slower speeds, longer trip times, and increased vehicle queue lengths. It is a significant issue in urban areas, leading to increased fuel consumption, air pollution, and economic losses. Traffic congestion can be influenced by several factors, including road design, traffic volume, weather conditions, and public transportation infrastructure (Litman, 2020).
The statistical analysis of traffic congestion involves the collection, interpretation, and modeling of data related to traffic flow and patterns (Miller & Hadi, 2019). The goal of this project is to explore and apply statistical techniques to analyze traffic congestion in a specific urban area, identify the primary causes, and recommend improvements for reducing congestion. The analysis will focus on factors such as traffic volume, road network characteristics, peak hours, and the role of public transportation. Therefore, this research study aims to apply statistical techniques to the analysis of traffic congestion in urban areas.
1.2 Statement of Problems
Investigation revealed that traffic congestion has become a pervasive issue in urban areas, leading to numerous challenges that affect daily life, the economy, and the environment. One of the most significant problems associated with congestion is the increased travel time, which results in lost productivity and higher transportation costs. As urban populations continue to grow, the demand for road space is consistently exceeding supply, leading to gridlocks that strain existing infrastructure.
In many urban centers, policymakers and urban planners struggle to make data-driven decisions due to the sheer volume of data and the complexity of traffic systems. Even though real-time traffic monitoring systems are in place, traffic congestion often remains unpredictable, especially during peak hours. The problem is compounded by the underutilization of available statistical models, which could provide deeper insights into the dynamic interactions between traffic-related variables and help forecast congestion more accurately.
Furthermore, while there are studies on congestion, they tend to focus primarily on either short-term solutions or specific urban areas, leaving a gap in long-term, city-wide strategies. Urban mobility requires a more holistic approach that takes into account the broader system of transportation and the interconnections between various factors that influence traffic flow. It is against the backdrop that this study seeks to identify key factors contributing to congestion and to develop actionable insights that can inform urban planning and traffic management policies.
1.3 Aim and Objectives of Study
The aim of the study is to statistically analyze the level of traffic congestion in the study area. The objectives of the study are as follows:
- To evaluate the effectiveness of existing traffic management strategies and their role in mitigating congestion, based on statistical modeling and simulations.
- To assess the relationship between traffic volume, road infrastructure, and peak-hour congestion, using real-time data and historical traffic records.
- To identify major factors that contribute to congestion in urban areas, and analyze traffic flow patterns using statistical techniques.
- To forecast traffic congestion patterns under different scenarios using predictive statistical models, aiding in the development of more responsive traffic management plans.
- To provide recommendations for improving urban transportation systems by optimizing road usage, public transport integration, and infrastructure development based on statistical findings.
1.4 Research Questions
Based on the objectives of the study, the following research questions are formulated to guide the investigation into traffic congestion in urban areas:
- What are the primary factors contributing to traffic congestion in urban areas, and how do these factors interact with each other?
- How do traffic volume and road infrastructure influence congestion patterns, especially during peak hours?
- What is the effectiveness of current traffic management strategies in reducing congestion, and what improvements can be made based on statistical analysis?
- How can statistical models predict future traffic congestion patterns under different scenarios, and how reliable are these predictions for urban planning purposes?
- What recommendations can be derived from statistical analysis to optimize urban transportation systems, including road usage, public transportation, and infrastructure development?
1.5 Research Hypothesis
Based on the objectives of this research study, the following hypotheses are proposed:
- H0: There is no significant relationship between traffic volume, road infrastructure, and peak-hour congestion, implying that changes in these factors do not influence the severity of congestion in urban areas.
- H1: There is a significant relationship between traffic volume, road infrastructure, and peak-hour congestion, such that changes in one of these factors influence the severity of congestion in urban areas.
1.6 Significance of Study
The outcome of this research will enable them to design more effective traffic management strategies and optimize infrastructure development, contributing to the smooth flow of traffic and the improvement of urban mobility.
For city commuters, the findings will highlight the primary factors contributing to congestion, which will help inform public awareness and encourage the adoption of alternative transport options.
Lastly, the study will be valuable for local government authorities, as it will enable them to better allocate resources and plan for future urban growth.

1.8 Limitations of the Study
A study of this nature is bound to experience certain problems as such the constraints imposed on the research include:
- Time: A study of this nature needs relatively long time during which information for accurate or at least near accurate inference could be drawn. The period of the study was short, time posed as constraints to the research.
- Cost: The research would have extended the survey to other area at the empirical level, but limitation as included cost of transportation to the source of material and the cost of time setting of the already completed work.

1.9 Definition of Terms
Traffic Congestion:
Traffic congestion refers to the situation where demand for road space exceeds available capacity, resulting in slower speeds, longer trip times, and increased vehicle queue lengths (Ewing & Cervero, 2010).
Traffic Flow:
Traffic flow is a term used to describe the movement of vehicles and people on a roadway. It is generally measured in vehicles per unit of time, such as vehicles per hour, and is influenced by factors such as road capacity, traffic signals, and the volume of traffic. Understanding traffic flow is essential for analyzing congestion and optimizing traffic management systems (Daganzo, 2005).
