Project – The Relationship between Public Transport Accessibility and Commuting Patterns among Workers in the Lagos Mainland Local Government Area

CHAPTER ONE

INTRODUCTION

1.1 Background to the Study

Public transportation is an important component of urban development because it enables workers, students, businesses and other residents to move between places of residence, employment and essential services. In rapidly urbanising cities, the availability, affordability, reliability and spatial accessibility of public transport can influence how people organise their daily activities and how frequently they travel. Public transport accessibility generally refers to the extent to which people can conveniently reach and use available transportation services in terms of distance to transport facilities, availability of vehicles, frequency of service, affordability, travel time and reliability. The relationship between accessibility and mobility is particularly important for workers because commuting is often a repeated journey that must be undertaken on a daily or near-daily basis. In Lagos, the rapid expansion of the metropolitan area has increased the number and length of commuter trips and has placed pressure on existing transport infrastructure and services. The Lagos Metropolitan Area Transport Authority (LAMATA) identifies increasing travel demand, congestion, high transport costs and inadequate public transport infrastructure among the major transportation challenges confronting the metropolis (LAMATA, 2024).

Lagos presents a particularly important context for examining public transport accessibility because of its large population, spatial expansion and concentration of employment and commercial activities in different parts of the metropolis. The mainland contains several major residential, commercial, industrial and institutional areas and is strongly connected to Lagos Island and other parts of the metropolitan region through road-based and mass-transit networks. Historical and contemporary transport studies show that movement between mainland residential areas and employment centres has long shaped commuting patterns in Lagos. Research on the history of urban transportation in metropolitan Lagos documented the importance of the mainland in housing workers who travelled towards employment areas on the Island, while more recent research continues to identify substantial commuting movements between different parts of the metropolis (IFRA-Nigeria, 2002; Afolabi et al., 2017). The spatial relationship between where workers live and where they work means that the availability of convenient public transportation can affect departure times, route selection, mode choice and the amount of time workers devote to commuting.

The public transport system in Lagos comprises multiple modes, including conventional commercial buses, Bus Rapid Transit (BRT), rail services, taxis and water transportation. The development of an integrated multimodal transport system has been a major component of Lagos State’s transportation strategy because reliance on a single mode or an inadequately connected network can increase congestion and reduce mobility. LAMATA’s Strategic Transport Master Plan identifies the need for integrated bus, rail, waterway and non-motorised transportation systems to respond to the metropolitan area’s changing travel demand. The authority has also implemented bus reforms and BRT services intended to improve the efficiency and accessibility of public transportation. The development of these services is relevant to workers because the availability of alternative modes can affect whether commuters use buses, rail, water transport, private vehicles or combinations of different modes to reach their workplaces. Consequently, public transport accessibility should be considered not merely in terms of whether transport exists, but in terms of the extent to which the available system provides convenient connections between residential locations and employment destinations (LAMATA, 2014; LAMATA, 2024).

Empirical research has demonstrated that characteristics of public transportation can influence commuting experiences and travel behaviour in Lagos. Alade, Olaseni and Adeniji (2019) examined commuters’ travel characteristics, modal choice and the performance of public transport options in Lagos and considered access to modes such as yellow buses, BRT and ferry services. Their study highlighted the importance of travel characteristics and service performance in understanding transport choices among Lagos commuters. Earlier, Olajide and Adebayo (2012) examined commuters’ opinions and experiences in Lagos and found that commercial vehicles were dominant in the city’s transport system, while congestion, passenger loading practices and other operational problems affected commuters’ experiences. The study also found that many respondents sometimes delayed leaving work in order to avoid evening congestion. These findings indicate that the characteristics and accessibility of public transport can shape not only the mode selected by workers but also the timing of their journeys and the ways in which they adjust their daily commuting routines (Alade et al., 2019; Olajide & Adebayo, 2012).

Accessibility also has an important economic and social dimension because transport difficulties can increase the time and financial resources required for workers to reach employment. Poor accessibility may result in longer journeys, multiple transfers, increased waiting time, higher transport expenditure and greater exposure to traffic congestion. In a study of transport poverty in a low-income Lagos community, Allen et al. (2022) found that inadequate public transportation and extended travel times generated significant opportunity costs for residents, with travel-related time costs affecting access to employment and other urban opportunities. Similarly, LAMATA has identified transport expenditure, congestion, inadequate infrastructure and the condition of public transport as significant challenges in Lagos. For workers, these conditions may influence commuting decisions, including when to leave home, which route to take, which transport mode to use and whether to combine different modes. Therefore, examining accessibility provides a useful basis for understanding variations in workers’ commuting patterns (Allen et al., 2022; LAMATA, 2024).

Commuting patterns encompass the regular characteristics of workers’ journeys, including frequency of travel, departure time, arrival time, travel duration, transport mode, route choice, number of transfers and, in some cases, the distance between residential and employment locations. These patterns are not fixed because workers may modify their behaviour in response to congestion, transport availability, fares, service reliability and other circumstances. A large-scale Lagos travel study involving 2,500 households found that more than 95% of residents depended on road transportation, while work and business trips were particularly prominent during weekdays. The study associated heavy reliance on road transportation with peak-period congestion and loss of valuable time. These findings demonstrate the importance of examining commuting as a behavioural response to the characteristics of the transport system rather than viewing travel simply as movement from one location to another (Oyesiku et al., 2015). More recent research on Lagos transport has similarly shown that accessibility and travel conditions can affect the experiences and decisions of commuters (Alade et al., 2019).

The Lagos Mainland Local Government Area provides an appropriate setting for examining the relationship between public transport accessibility and workers’ commuting patterns because it is embedded within a densely connected metropolitan transport environment characterised by substantial daily movement. Recent research specifically conducted in Lagos Mainland found concerns relating to transport service quality, vehicle conditions, operator conduct, fares, infrastructure and commuter satisfaction, demonstrating that transport conditions remain relevant to the experience of people using public transportation in the area (Irinyemi, 2024). In addition, research involving passengers on Mainland and Island bus routes during the COVID-19 period demonstrated that accessibility, route characteristics, boarding frequency and operational conditions influenced commuters’ decisions concerning public bus use (Mogaji et al., 2022). Although Lagos has continued to develop BRT, rail and other transport infrastructure, the existence of transport services does not necessarily mean that every worker has equal or convenient access to them. This creates a need to examine how differences in accessibility relate specifically to workers’ commuting patterns within Lagos Mainland Local Government Area.

1.2 Statement of the Problem

The growing demand for urban transportation in Lagos has created persistent challenges for workers who depend on public transportation for daily commuting. Although the city has developed BRT, rail, water transportation and conventional bus services, congestion, service limitations, transport costs and uneven accessibility continue to affect the commuting experience. LAMATA identifies the rapid growth in commuter trips, congestion, deteriorating road conditions and transport costs as significant challenges within the metropolitan transport system (LAMATA, 2024). For workers, these conditions can translate into long waiting periods, unpredictable journey times, late arrival at workplaces and difficulties in planning daily activities. The problem is therefore not simply the availability of transportation but whether available public transport services are sufficiently accessible, reliable and affordable to support workers’ daily mobility.

A second problem concerns the effects of limited accessibility on workers’ actual commuting behaviour. When public transport services are difficult to access or unreliable, workers may alter departure times, select alternative routes, change transport modes, combine multiple modes or increase the amount of time allocated to commuting. Research on Lagos commuters has documented how congestion and transport-service conditions influence daily travel experiences and decisions. Olajide and Adebayo (2012) found that commuters sometimes stayed late at work to avoid evening congestion, while Allen et al. (2022) demonstrated that long travel times associated with inadequate public transport generated measurable opportunity costs for residents of a Lagos low-income community. These findings indicate that transport conditions can influence how workers organise their journeys, yet there remains a need to examine these relationships within the specific context of workers in Lagos Mainland Local Government Area.

A further problem is that accessibility is not necessarily experienced uniformly by all public transport users. Factors such as proximity to bus stops or terminals, frequency of available vehicles, affordability of fares, reliability, travel time, route connectivity and availability of alternative modes can create different levels of transport accessibility among workers. A study of Lagos public transport users found that travel distance, travel time, cost and modal characteristics were important dimensions of public transport use, while research specifically focused on Lagos Mainland identified problems relating to vehicle quality, operator behaviour, fares and infrastructure (Alade et al., 2019; Irinyemi, 2024). These conditions may produce differences in commuting frequency, departure times, travel duration and modal choice among workers who live or work within the same local government area. Consequently, there is a need for empirical research that examines accessibility as a multidimensional phenomenon and relates it directly to the commuting patterns of workers.

The central problem addressed by this study is therefore the limited empirical evidence on the relationship between public transport accessibility and commuting patterns among workers in Lagos Mainland Local Government Area. Existing studies have examined Lagos transportation generally, public transport user characteristics, commuter experiences, transport poverty and service quality, while other studies have examined specific transport corridors or modes. However, fewer studies have specifically focused on how accessibility dimensions such as availability, affordability, proximity, reliability and travel time relate to the commuting patterns of workers within Lagos Mainland Local Government Area. This gap is important because commuting behaviour provides an observable indication of how workers respond to the transport environment. Understanding the relationship can provide useful evidence for transport planning, service improvement and policies intended to make public transportation more accessible and responsive to workers’ mobility needs (Allen et al., 2022; Irinyemi, 2024; LAMATA, 2024).

1.6 Significance of the Study

Workers

The study will be useful to workers in Lagos Mainland Local Government Area because it will provide evidence concerning the relationship between transportation accessibility and their daily commuting experiences. The findings may help identify the accessibility conditions that are most strongly associated with travel frequency, journey duration, departure times and mode choice.

Lagos State Government

The findings may assist the Lagos State Government in understanding how workers experience public transportation at the local-government level. Evidence from the study could contribute to transport planning, infrastructure development and policies aimed at improving the accessibility and efficiency of public transportation.

Lagos Metropolitan Area Transport Authority

The study may provide useful information for LAMATA in relation to route planning, service frequency, accessibility and integration of different public transport modes. LAMATA’s mandate includes planning, coordinating and developing an integrated multimodal transport system for Lagos, making evidence on commuter accessibility relevant to its planning responsibilities (LAMATA, 2024).

Transport Operators

Commercial bus operators and other public transport providers may benefit from information concerning the factors that influence workers’ commuting choices. The findings may help operators better understand the importance of reliability, affordability, accessibility and travel-time efficiency to regular commuters.

Urban Planners

The findings may assist urban and transport planners in understanding the connection between land-use patterns, employment locations and public transport accessibility. This may support planning approaches that reduce unnecessary travel burdens and improve connections between residential areas and employment centres.

Employers

Employers may benefit from greater understanding of the transport conditions faced by their workers. Evidence concerning commuting duration, reliability and transport accessibility may help organisations consider practical measures such as flexible work arrangements, staff transportation schemes or adjustments to working schedules where appropriate.

Researchers and Students

The study will contribute to the literature on urban transportation, public transport accessibility, mobility and commuting behaviour in Nigeria. It may also provide a reference for future research examining transport accessibility at the local-government, community or occupational level.

1.7 Scope of the Study

The study will focus on the relationship between public transport accessibility and commuting patterns among workers in Lagos Mainland Local Government Area.

The content scope will cover public transport accessibility and commuting patterns. Public transport accessibility will be examined through dimensions such as availability, proximity, affordability, reliability, frequency and travel time. Commuting patterns will include transport mode, commuting frequency, departure time, journey duration, number of transfers and regularity of travel to and from work.

The geographical scope will be restricted to Lagos Mainland Local Government Area, Lagos State. The study will not attempt to represent all local government areas in Lagos State.

The population scope will consist of workers who regularly commute within, into or out of Lagos Mainland Local Government Area and who use public transportation as part or all of their regular journey to work.

The study will focus on public transportation and will not treat private car use as the principal form of transport accessibility, although respondents may be asked about alternative modes where this is relevant to their commuting decisions.
