Enhancing Road Safety in Kenya Through Data-Driven Mapping and Strategic Interventions

---

Introduction

Road traffic incidents remain a pressing concern in Kenya, leading to significant loss of life, injuries, and economic setbacks. In 2024 alone, over 4,000 fatalities were recorded, with pedestrians constituting a substantial portion of these deaths. To address this, a comprehensive approach leveraging data collection, analysis, and visualisation is essential for informed decision-making and effective road safety interventions.

Data Collection Methodology

The foundation of effective road safety strategies lies in accurate and comprehensive data. Kenya has made significant strides in this area through the implementation of advanced data collection tools and systems:

• Geographic Information System (GIS) Devices: The government has introduced GIS-enabled devices to capture real-time accident data, addressing previous challenges of data accuracy and reliability . (Gov’t introduces road accidents data collection device – Kenya News Agency)

• Integrated Transport Management System (iTMS): NTSA's iTMS facilitates automatic data gathering by traffic officers, enhancing the efficiency of data collection and enabling prompt action against traffic violations . (NTSA Unveils Smart System to Curb Accidents - Kenyans.co.ke)

• Collaborative Data Sources: Data is aggregated from multiple stakeholders, including the National Police Service, health facilities, insurance companies, and road agencies, ensuring a holistic view of road safety dynamics.

publicly available data and official sources

Key data points include:

• Incident Type: Deaths, injuries, or property damage

• Vehicle Type: Motorcycles, three-wheelers, cars, pickups, lorries

• Location: Geographic markers (e.g., Nairobi, Kisumu, Eldoret)

• Time: Incident date and time

• Causes: Speeding, carelessness, weather, etc.

Incident Distribution by Vehicle Type

1. Motorcycles

• Share: Likely 50-60% of incidents

• Nature: Frequent injuries and deaths; carelessness (33%), wet roads (21%), speed (17.5%)

• Hotspots: Nairobi and rural unpaved routes

• Observation: About one-third of riders lack helmets

2. Three-Wheelers

• Share: Possibly 5-10%

• Nature: Crashes with bigger vehicles or tipping due to overload

• Hotspots: Suburban areas like Mombasa and Kisumu

3. Cars

• Share: Roughly 20-25%

• Nature: Pedestrian impacts or pile-ups

• Hotspots: Nairobi-Nakuru corridor

4. Pickups

• Share: Around 5-10%

• Nature: Overloading, equipment failures

• Hotspots: Farming zones and inter-town roads

5. Lorries

• Share: About 5-10%

• Nature: Loss of control, major crashes (e.g., Kericho 2023 crash)

• Hotspots: Highways like Nairobi-Mombasa

Visualisation and Mapping of Incidents

Transforming raw data into actionable insights requires effective visualisation: (NTSA adopts random vehicle inspections to reduce crashes | Nation)

• Heatmaps: These illustrate high-incidence areas, aiding in the identification of accident hotspots.

• Interactive Dashboards: Allow stakeholders to filter data by vehicle type, time, and location, facilitating targeted interventions.

• Temporal Analysis: Tracking incidents over time helps in understanding patterns and the impact of implemented measures.

Such visual tools are instrumental in strategic planning and resource allocation for road safety improvements.

Visualization: Interactive Maps

Interactive maps can clarify incident trends:

• Density Heatmap: High-incident zones like Nairobi, Eldoret, Kericho

• Vehicle Filter: Show motorcycle clusters in rural zones and lorries on highways

• Time Feature: Track peaks (e.g., weekends, evenings)

• Sample Output: Maps might spotlight Nairobi motorcycle spikes or Kericho’s post-2023 lorry crashes

Key Findings

Analysis of the collected data reveals critical insights:

• Motorcycle-Related Incidents: Motorcycles, commonly known as boda bodas, are involved in a significant proportion of accidents. NTSA reports that boda boda operators contribute to approximately 70% of road crashes (Gov’t introduces road accidents data collection device – Kenya News Agency).

• High-Risk Corridors: Certain highways, such as the Nairobi-Nakuru and Nairobi-Mombasa routes, have been identified as accident-prone areas due to factors like speeding and poor road conditions (Gov't To Erect Surveillance Cameras On Major Highways To Curb Road Accidents - The Mount Kenya Times).

• Pedestrian Vulnerability: Pedestrians account for a substantial number of fatalities, highlighting the need for improved pedestrian infrastructure and awareness campaigns.

Basic Statistical Analysis

Based on a hypothetical dataset of 10,000 incidents in 2024:

• Vehicle Breakdown:

  • Motorcycles: 5,500 (55%)

  • Cars: 2,000 (20%)

  • Three-Wheelers: 800 (8%)

  • Pickups: 900 (9%)

  • Lorries: 800 (8%)

• Death Rates:

  • Motorcycles: ~15% (825 deaths)

  • Lorries: ~20% (160 deaths)

  • Cars: ~10% (200 deaths)

• Regional Spread:

  • Nairobi: 30% (3,000 incidents)

  • Central Kenya (e.g., Thika): 20%

  • Western Kenya (e.g., Kericho): 15%

• Correlations:

  • Motorcycle crashes correlate with helmet non-use (r = 0.7) and poor rural roads (r = 0.6)

Strategic Interventions and Measures

In response to these findings, several measures have been implemented:

• Deployment of Speed Cameras: Installation of speed cameras on major highways has led to a notable reduction in accidents, particularly on the Northern Corridor (Speed cameras have reduced road crashes, says NTSA).

• National Road Safety Action Plan (2024-2028): This comprehensive plan encompasses infrastructure improvements, stricter enforcement of traffic laws, public awareness campaigns, and post-crash care services (National Road Safety Action Plan (2024-2028) Launched to Curb Road Accidents | Ministry of Roads and Transport).

• Regulation of Boda Boda Sector: With over 2.5 million registered boda bodas, efforts are underway to enhance regulation, including rider training and enforcement of safety standards (Counties, NTSA team up to reduce road carnage – Kenya News Agency).

Key Findings

1. Motorcycle Prevalence: Most incidents stem from motorcycle use and safety lapses

2. Lorry Impact: Lower incident count but higher severity

3. Geographic Trends: Urban areas see more car and tuk-tuk issues; rural areas have more motorcycle incidents

4. Common Causes: Speeding, reckless driving, and weather are widespread factors

Recommendations

1. Awareness Drives: Promote helmets and safety gear

2. Road Upgrades: Improve infrastructure, especially in rural zones and for freight routes

3. Data Integration: Merge NTSA, police, and online posts for live insights

4. Public Tools: Offer visual dashboards and incident maps for planning

Conclusion

The integration of advanced data collection methods and strategic interventions marks a significant step towards improving road safety in Kenya. By leveraging technology and collaborative efforts, the country aims to reduce road traffic incidents, safeguard lives, and promote sustainable development.
