Statistical Analysis of Road Traffic Accidents in Port Harcourt, Rivers State: Causes, Times, Locations, and Outcomes

ABSTRACT

Road traffic accidents (RTAs) represent one of the leading causes of injuries and deaths in Nigeria. This study statistically analyzes the causes, times, locations, and outcomes of road traffic accidents in Port Harcourt, Rivers State, using official data from the Federal Road Safety Corps (FRSC) and hospital records covering a five-year period (2019–2023).

Through descriptive and inferential statistical methods, including frequency distribution, chi-square tests, and trend analysis, the study identifies major accident determinants. The findings reveal that human factors—such as speeding, reckless driving, and use of mobile phones while driving—contribute more to accidents than mechanical or environmental causes. Moreover, accidents occur most frequently during weekends and evening hours, particularly along major highways like Aba Road and East-West Road.

The study concludes that effective enforcement of traffic laws, public awareness campaigns, and proper road maintenance are essential for reducing accident rates. Consequently, it recommends stronger collaboration between the FRSC, transport unions, and local authorities to promote safer driving behavior in Port Harcourt.

CHAPTER ONE: INTRODUCTION

1.1 Background of the Study

Transportation plays a vital role in the economic and social development of every nation. In Nigeria, road transport remains the most common means of movement for people and goods due to its flexibility and accessibility. However, the rising number of road traffic accidents has become a serious public health and economic challenge.

In Port Harcourt, the capital of Rivers State, road traffic accidents occur almost daily. The city’s rapid urbanization, population growth, and increasing vehicle ownership have all contributed to traffic congestion and frequent collisions. Unfortunately, these incidents result in significant loss of life, injuries, and property damage.

Several factors influence the occurrence of road accidents. They include human errors, poor road design, inadequate signage, bad weather conditions, and vehicle defects. Although the Federal Road Safety Corps (FRSC) and state agencies record accident data, detailed statistical analysis is often lacking. Therefore, this study employs statistical techniques to examine the patterns and determinants of RTAs in Port Harcourt. By doing so, it provides empirical insights that can guide road safety policies and accident prevention strategies.

1.2 Statement of the Problem

Despite continuous road safety campaigns, accident rates in Port Harcourt remain high. Many studies focus on general national statistics without addressing local patterns of causes, times, or accident-prone locations. As a result, policymakers lack accurate and city-specific information for targeted interventions.

Additionally, most accident reports provide raw figures without deeper statistical interpretation. Consequently, the underlying trends and causal relationships remain poorly understood. To fill this gap, this study conducts a comprehensive statistical analysis of accident data in Port Harcourt, identifying the main causes, times of occurrence, critical locations, and likely outcomes.

1.3 Objectives of the Study

The main objective of this study is to analyze road traffic accidents in Port Harcourt using statistical methods to determine their causes, timing, locations, and outcomes.

Specifically, the study aims to:

1. Identify the major causes of road traffic accidents in Port Harcourt.

2. Examine the distribution of accidents across different times and days.

3. Analyze the most accident-prone locations within the metropolis.

4. Assess the severity and outcomes (fatal, serious, or minor injuries) of reported accidents.

5. Suggest practical recommendations for reducing accident frequency and severity.

1.4 Research Questions

1. What are the main causes of road traffic accidents in Port Harcourt?

2. At what times or days do accidents most frequently occur?

3. Which locations record the highest number of accidents?

4. What are the typical outcomes of road accidents in the city?

5. How can statistical insights help design more effective safety interventions?

1.5 Research Hypotheses

Null Hypothesis (H₀):
There is no significant relationship between accident causes, time of occurrence, and severity in Port Harcourt.

Alternative Hypothesis (H₁):
There is a significant relationship between accident causes, time of occurrence, and severity in Port Harcourt.

1.6 Significance of the Study

This study is important because it provides data-driven insights into one of Nigeria’s most pressing safety challenges. Firstly, it helps government agencies and policymakers understand the real patterns and causes of RTAs in Port Harcourt. Secondly, it supports the FRSC and local traffic management authorities in improving road safety planning.

Moreover, the study contributes to academic knowledge by applying statistical models to real-world transportation data. It also informs non-governmental organizations and the general public about accident risks, thereby encouraging safer driving behavior. Ultimately, the results may lead to a reduction in accident rates and associated socio-economic costs.

1.7 Scope of the Study

The study covers road traffic accidents that occurred in Port Harcourt Metropolis between 2019 and 2023. It focuses on identifying accident causes, times, locations, and outcomes using data obtained from FRSC, Rivers State Traffic Management Authority (TIMARIV), and selected hospital records. The research excludes minor incidents not officially reported to authorities.

1.8 Limitations of the Study

The study relies on secondary data, which may contain missing or inconsistent records. Some accidents, especially minor ones, may go unreported. Additionally, external factors such as weather and alcohol use are not always properly documented. Despite these limitations, statistical techniques like data cleaning and smoothing were used to ensure credible and accurate results.

1.9 Definition of Key Terms

• Road Traffic Accident (RTA): Any incident on a public road involving one or more vehicles that results in injury, death, or property damage.

• Severity: The extent of damage or injury resulting from an accident, categorized as fatal, serious, or minor.

• Accident Frequency: The number of accidents occurring within a given period.

• Descriptive Statistics: Statistical tools used to summarize data characteristics, such as frequency and percentages.

• Trend Analysis: A method used to identify patterns or directions of data changes over time.
