Abstract

Gender-based violence (GBV) on public transport is a daily reality for many women and often goes unreported, which further worsens its impact on women's mobility and well-being. Using survey data from Cairo, Egypt, this study reveals that safety and security concerns are the most significant barriers to women's use of public transport. In the context of limited affordable alternatives, many women are forced to continue using unsafe public transit despite the risks, resulting in severe consequences for the affected women, including inaccessibility and social exclusion, financial stress, and psychological trauma. GBV in transit leads to lost opportunities, reduced participation in activities, and entrenched exclusion. Open-ended responses from participants underscore how structural and cultural norms shape these experiences; prevalent social perceptions and unclear legal definitions of harassment perpetuate under-reporting and impunity. Based on the findings, we recommend a bottom-up prevention strategy that integrates technological, social, and institutional interventions.

Introduction

The inclusive city is one of the pillars of the UN Sustainable Development Goals: discrimination based on gender should be eradicated. But cities are not gender-neutral — gender significantly shapes the experience of moving around a city. Although women represent roughly half the world's population, they do not enjoy the same freedom of movement as men, which limits their participation in economic and social life.

Public transport (PT) is the backbone of sustainable urban mobility, yet it often fails to serve women equally. Safety is one of the main barriers: women feel less safe than men at nearly every stage of a PT trip — on board, and while waiting at the station — and that feeling of insecurity shapes short- and long-term travel decisions, from daily mode choice to where to live and work.

This insecurity is deeply linked to gender-based violence, particularly sexual harassment, which is the most common and visible form of violence encountered in transit settings. This study uses survey data from Cairo, Egypt — the largest metropolitan area in the MENA region, home to roughly 23 million people — to understand the dimensions of GBV in transit and how it shapes women's travel decisions, and to surface what women themselves propose to improve safety.

The MENA region is one of the least-studied areas for GBV in public transport in the current literature — despite violence against women in public spaces being widely observed and rarely discussed. That contradiction gives the paper its title.

Contributions

  • Map women's perception of safety on PT, and what would improve it
  • Benchmark reported GBV in Cairo against other world cities
  • Capture the full anatomy of an incident — time, place, conditions, response, aftermath, and the survivor's own proposed solution

Why Cairo

  • ~23.1 million residents in Greater Cairo (2025), projected to reach 28.5 million by 2035
  • One of the world's most congested cities; congestion cost an estimated US$8 billion in 2016
  • Home to Africa's oldest metro, alongside informal paratransit microbuses that carry over half of all PT trips
03 · Background

Literature review

Gendered travel behavior

Women's travel needs differ from men's, shaped by their disproportionate role as primary caregivers. Their trips are more complex — chaining home, work, childcare, and shopping together — rather than the direct commute more typical of men. Across cities as different as Auckland, Dublin, Hanoi, Helsinki, and Manila, women make shorter trips, avoid peak-hour and nighttime travel, and have less access to private cars — a constraint observed in both developing contexts (India, China) and wealthy ones (the US, Germany, Sweden, Finland).

Yet women are not a homogeneous group. Low-income women in Dhaka face a distinct mix of infrastructural gaps and conservative social taboos; young ethnic-minority women in Auckland navigate "stranger danger" by pre-planning night trips and performing confidence; riders wearing visible religious dress report heightened discrimination. Treating "women" as a single vulnerable category obscures these intersecting burdens.

Gender-based violence in public transport

GBV is any act of violence against someone because of their gender — physical, sexual, psychological, economic, or emotional. On transit, it ranges across a continuum, from sexist jokes and staring to groping and, in rare but real cases, assault. Researchers typically group harassment acts into three families:

Nonverbal

  • Staring / leering
  • Suggestive facial expressions
  • Exposure or public masturbation

Verbal

  • Catcalling, sexual comments
  • Offensive language
  • Threats or sexual invitations

Physical

  • Blocking the way
  • Invasion of privacy
  • Groping, touching, rubbing

The pattern repeats worldwide, at different intensities: up to 97% of women in São Paulo report harassment; rates sit between 50–80% in Mexico City, Bogotá, and Santiago; 78% in Karachi and over 85% in Nairobi. Most women respond by staying quiet or walking away rather than confronting the harasser — and the incidents are massively under-reported everywhere, from 32% saying nothing in London to 93% not reporting at all in Manizales, Colombia.

How Cairo compares to other cities

The gap this study fills

Existing research is geographically skewed toward major cities outside the MENA region, and GBV in transit is usually studied in isolation from broader urban planning. No prior study brings together timing, perpetrator identity, victim response, emotional aftermath, and the survivor's own proposed fix in one unified framework — which is exactly the gap this paper sets out to close.

04 · Fieldwork

Case study, data and methods

Cairo is the capital of Egypt and the largest city in the MENA region — about 10.3 million residents within the city, 48% of them women, inside a wider metropolitan area of 23.1 million. Its transport system leans heavily on informal paratransit: privately-owned 14-seat microbuses that carry over half of all PT trips, alongside Africa's oldest metro system and a public bus fleet that is, per capita, among the smallest in the region.

The research team ran a five-part online survey (via LimeSurvey, in Arabic and English) from January to April 2021, distributed through Facebook, LinkedIn, and WhatsApp. Only women, 18 or older, residing in Cairo and using PT, were eligible.

Screening responses 1,535 Travel behavior 739 Barriers to PT use 491 General GBV questions 397 Most severe incident 310 Full survey, incl. demographics 227

Because the survey was long, attrition was high — but a dedicated attrition check found dropouts' early answers tracked closely with those who finished, so each section's respondents were analyzed as-is (the Retained Sample) rather than discarded. The final complete sample (N = 227) skews young — 78% are 18–24 and 88% single — and more educated than the general population (65% hold a bachelor's degree or higher), which the authors are transparent about as a limitation.

An open-ended question let respondents describe GBV in their own words. Those answers were clustered using Latent Dirichlet Allocation (LDA) topic modeling, tuned via coherence, log-likelihood, and perplexity checks to four topics.

05 · Findings

Results

Who's riding, and why

Respondents were regular riders — about 60% use PT at least twice a week. Most are captive riders: two-thirds cite "no other option" as their reason for using PT, rather than cost or convenience. Only about 1 in 5 owns a car.

What keeps women off public transport

Of 11 possible barriers, safety at the station and safety on board ranked first and second — ahead of vehicle condition, transfers, and trip duration. Stations, often less crowded than the vehicle itself, felt less safe than being on board — a pattern also documented in the UK, Australia, Sweden, Italy, Japan, and France.

Trip purpose matters: mandatory trips like commuting or school were rarely canceled over safety concerns, but leisure and shopping trips were likely to be cancelled by nearly 60% of respondents — a quieter, cumulative form of exclusion from everyday life.

The five most common unwanted behaviors, each reported by at least half of respondents, were all verbal or nonverbal: staring, catcalling, sexual comments, suggestive facial expressions, and offensive language. Physical acts — blocking the way, invasion of privacy — were reported less often but still real. Most incidents cluster late at night and in the early morning (9pm–7am), when demand — and the presence of other passengers — is lowest.

Faced with these acts, women mostly did not confront the person responsible: across almost every behavior, not reacting or walking away are the two most common responses, together accounting for roughly two-thirds to three-quarters of answers. Verbal retaliation is the most common form of pushback — highest for the everyday, high-frequency acts like offensive language (32.2%) and catcalling (31.4%) — while asking a fellow passenger or the driver for help is rare almost everywhere. That's less a sign of passivity than a coping strategy shaped by fear, distrust of authorities, and a lack of visible support.

The most severe incident

Asked to describe their single worst experience, 42% of respondents pointed to a physical act, 35% to nonverbal harassment, and 14% to verbal abuse — a reversal from day-to-day harassment, where verbal and nonverbal acts dominate. Most incidents (71%) happened in an averagely crowded setting, and in 16% of cases the harasser was a transit worker — a driver or conductor — rather than a fellow passenger.

97.5% of women who experienced their most severe incident did not report it to any authority.

The reasons cluster into three layers: practical (the incident was over too fast to act, or there was no witness), psychological (fear of not being believed, shock, fear of being blamed), and systemic (distrust that authorities would investigate, no clear way to report, weak legal protection).

Who is affected, and how it feels afterward

The most severe incidents skew strikingly young: the average age at the time of the incident was 18, with the distribution concentrated in the teens and early twenties and a long tail stretching out to women in their thirties — meaning many of these "most severe" experiences happened while respondents were still girls, not adult women.

Asked how the most severe incident made them feel, respondents could select multiple emotions at once — and the top responses were unambiguous. Outrage (59.8%) and terror (55%) led, followed closely by confusion (45.4%) and feeling abused (43.6%). Fewer respondents described dissociation or minimization, suggesting most women recognized these incidents as serious violations in the moment, rather than downplaying them internally — even as nearly all stayed silent about it afterward.

In their own words: four themes

An open-ended question let respondents describe GBV freely. Clustering the answers with topic modeling surfaced four recurring themes:

TOPIC 01

Social perceptions of GBV

How violence — especially verbal, gendered violence — is understood and normalized, and how that needs to be actively challenged.

TOPIC 02

Harassment in public spaces

Fear and discomfort tied to specific places — the street, the station — pointing to an urgent need for safer public and transit environments.

TOPIC 03

Types and descriptions of GBV

Women clearly distinguish sexual from physical violence — evidence that legal clarity and trained enforcement would resonate.

TOPIC 04

Structural & individual dimensions

Violence as both individual behavior and structural context — calling for institutional reform alongside community action.

06 · So what

Discussion & recommendations

GBV on transit is a universal phenomenon with a strikingly consistent shape from Cairo to São Paulo to London: most women face it, most stay quiet, and most keep riding anyway because they have no real alternative. That combination — high exposure, low reporting, low exit options — is what turns a safety problem into a driver of social exclusion: women skip leisure and shopping trips, withdraw from public life, and absorb the cost in time, money, and mental health.

The authors frame their recommendations in two tiers — what can move quickly, and what has to be sustained over years.

Immediate, low-infrastructure moves

  • Technology: emergency buttons and surveillance cameras across the network
  • Environment: well-lit corridors and visible, trained security on board and at stations
  • Reporting: digital kiosks, panic apps, QR codes, helplines, anonymous platforms
  • Enforcement: transparent, visibly-followed-through reporting processes

Sustained, structural change

  • Awareness: nationwide campaigns built with local communities and survivor networks
  • Inclusion: gender-sensitive hiring — more women drivers and controllers
  • Training: trauma-informed, gender-sensitive training for transport staff, police, and courts

What travels across borders less well is the specific fix. Cairo respondents strongly favored surveillance cameras — a measure Australian riders view with skepticism. French riders lean toward personal tech, like smartphone alarms. Bangladeshi respondents pushed harder for systemic change: stricter enforcement, more vehicles, women-only carriages. The problem is universal; the right intervention is local.

07 · In fairness

Limitations

The survey's length drove significant drop-off — but an attrition check found dropouts' early answers tracked the completers closely, so the final pattern of results is unlikely to be an artifact of who stuck around. The complete sample (N = 227) is modest and skews young and well-educated, in line with comparable studies elsewhere (Dhaka N = 225, Manizales N = 296, Lucknow N = 200). Because recruitment ran entirely online, older and less digitally-connected women are under-represented; face-to-face interviews were judged likely to introduce their own bias, given how private these incidents are. The analysis is intentionally descriptive rather than causal — appropriate for establishing a first baseline in a region this under-studied, but a clear invitation for future modeling work.

08 · Terminus

Conclusion

GBV on public transport is close to universal — nearly all women experience it, yet almost no one intervenes seriously to stop it. What stands out in this data is how similar the pattern looks whether the city is rich or poor, dense or sprawling: cities everywhere are still not designed around the needs of half their population.

That similarity is also the opportunity. A shared underlying pattern of need means a shared policy foundation is possible — one that treats safety and dignity as non-negotiable parts of public transport design, built from what women who actually ride the system say they need, rather than imposed from the top down.
