The Africa Regional Road Safety Seminar was held on the 8^th and 9^th of October 2024 in Nairobi. The seminar is organized by the Global Road Safety Partnership (GRSP), the Kenyan Red Cross Society (KRCS), the United Nations Economic Commission for Africa (UNECA) and the International Road Assessment Programme (iRAP). This seminar sought to bring together representatives from the public and private sector and GRSP’s road safety community to exchange knowledge and ideas on key road safety issues. These invaluable insights into road safety in the African context and the iRAP system, greatly assist in ensuring that our ongoing road safety projects align with global standards.

At ITEC Engineering, we’re proud to be part of a project by the Kenya National Highways Authority (KeNHA) to improve road safety through the iRAP Star Rating system. This ongoing project, focuses on both Pre- and Post-Opening road safety audits, iRAP Star Rating Assessments and black spot identification and development of Management Guidelines, Road Safety Policy and Strategy.

What is the iRAP Star Rating System?

The iRAP (International Road Assessment Programme) Star Rating Assessment is a standardised methodology designed to evaluate the safety of road infrastructure. It evaluates how well a road protects its users, from vehicle occupants to motorcyclists, pedestrians, and cyclists. The system assigns a safety rating from 1 star (least safe) to 5 stars (most safe) based on risk factors such as road design, traffic control measures, and the likelihood of collisions.

The key advantage of iRAP lies in its evidence-based framework which follows internationally recognised best practices. By systematically assessing roads, iRAP helps identify areas where safety improvements are needed and provides detailed recommendations for interventions to reduce risks and prevent accidents.

Why Governments and Consultants Embrace iRAP

The UN Global Road Safety Performance Target 3 aims for all new roads to meet technical standards that prioritize road safety for all users or achieve a 3-star rating by 2030. Target 4 specifies that by 2030, over 75% of travel on existing roads should take place on roads that meet these safety-focused technical standards for all users.

In countries like Kenya, where road fatalities are a major concern, iRAP Star Rating Assessments offer a proactive approach. Rather than reacting to accidents after they occur, the system enables engineers and policymakers to identify and address potential safety risks in advance. Roads rated 3 stars or higher are significantly safer, and the program aims to ensure that all roads ultimately meet this standard.

To achieve this, the methodologies adopted include the following:

1. Crash Risk Mapping utilises crash data to show the distribution of recorded fatalities and serious injuries across a road network.
2. Star Ratings offer a straightforward, objective measure of how safe a road’s design is for its users.
3. Fatality Estimation Mapping depicts the expected number and distribution of fatalities and serious injuries across a road network.
4. Safer Road Investment Plans (SRIP) draws on approximately 90 proven road improvement strategies to develop cost-effective, life-saving infrastructure options.
5. Performance Tracking then uses Star Ratings and Crash Risk Mapping to monitor road safety performance and inform policy decisions.

Once assessed, roads receive targeted safety treatments, such as enhanced signage, traffic calming measures, or the addition of pedestrian walkways, ensuring they become safer for all road users.

ITEC Engineering’s Role in Road Safety

At ITEC Engineering, we are leveraging iRAP methodologies as part of our partnership with KeNHA and AfDB to improve the safety of key transport corridors in Kenya. As part of the project, our team is carrying out Road Safety Audits of the Kenol-Sagana-Marua (A2) road and performing Star Rating Assessments of several major road corridors across the country.

Our tasks involve:

• Identifying high-collision areas through Hazardous/Black Spot Management and recommending safety interventions
• Conducting Star Rating Assessments using the iRAP system to evaluate road safety levels
• Generating traffic volume projections based on current and future land use patterns

• Developing a Black Spot Management Guideline, which will guide future road safety interventions on high-risk sections of Kenya’s national highways.
• Updating KeNHA’s Road Safety Management Policy and Strategy to align with international standards and best practices.

Through these efforts, we help inform decision-makers on the best interventions to implement, packaging our findings into actionable projects aimed at reducing road accidents and fatalities.

Why the iRAP Star Rating System is Crucial for Kenya

Kenya’s road network is a vital artery for its economy, connecting cities, towns, and rural areas, and supporting trade and commerce. However, these roads are also the sites of thousands of accidents each year. By applying the iRAP Star Rating methodology, Kenya can systematically improve the safety of its road infrastructure and, in turn, reduce the number of fatalities and serious injuries.

Our work at ITEC Engineering supports Kenya’s Vision 2030, which prioritises the development of safe and reliable infrastructure. Through our work, we identify high-risk areas and implement targeted safety measures to ensure that as Kenya’s roads expand, they do so with safety as atop priority.

Driving Change Together

At ITEC Engineering, we believe that road safety should never be compromised. By embracing cutting-edge methodologies like iRAP, we’re paving the way for safer roads, fewer accidents, and a better future for all road users in Kenya.

Introduction

Imagine a small town in Kenya called Kijiji, which used to be quite isolated due to poor road conditions. Farmers struggled to get their produce to larger markets, and children often had difficulty getting to school during the rainy season. The local economy was stagnating, and the community faced numerous challenges.

To remedy scenarios like these, the Kenyan government through its Road Authority decides to invest in improving the road network connecting Kijiji to the nearest major town. Before starting the construction project, they engage a consultant to conduct thorough financial and economic evaluations. These evaluations involve assessing the potential costs and benefits, considering factors like construction expenses, expected travel time savings, increased trade opportunities, and overall economic and social impact on the region.

After the evaluations confirm the project’s feasibility and potential benefits, construction can begin. The new road is completed within a year or more, significantly reducing travel time between Kijiji and the city. Farmers can now transport their produce more efficiently, leading to fresher goods and better prices at markets and beyond. Children can attend school regularly, and local businesses start to thrive due to increased accessibility.

As a result, Kijiji transforms into a bustling community with a growing local economy. Such success stories can demonstrate how careful financial and economic evaluation can lead to impactful infrastructure projects, driving development and improving lives in historically inaccessible regions. As Kenya and many other countries continue to invest in their road networks to unlock economic and social gains, financial and economic evaluations become crucial.

Why Do We Need Financial and Economic Evaluations?

Financial and economic evaluations are vital in road infrastructure projects for several reasons:

1. Optimizing Resource Allocation: Governments often face budget constraints. Evaluations help prioritize projects that offer the highest returns on investment, ensuring optimal use of limited resources.
2. Ensuring Economic Viability: These evaluations determine whether a project is economically justified, considering both the costs involved and the anticipated benefits over time.
3. Informing Policy and Budget Decisions: By providing a clear picture of a project’s economic impact, these evaluations assist in the national budgeting process, aligning road investments with broader economic goals.

Aligning National Budgets with Road Investment Appraisals

The national budgeting process is a critical component of public sector financial management, determining how resources are allocated across various sectors. In the context of road investments, economic appraisals ensure that proposed projects align with national priorities and deliver value for money. This alignment is essential for:

• Rationalizing Expenditure: Economic evaluations justify the allocation of funds to road projects by demonstrating their potential to stimulate economic growth, reduce transport costs, and enhance connectivity.
• Maximizing Economic Benefits: By focusing on projects with the highest economic returns, governments can ensure that investments contribute significantly to national development objectives.

Concepts in Economic Appraisal

Economic appraisal involves a comprehensive analysis of a project’s costs and benefits to determine its economic feasibility.

Key concepts include:

• Cost-Benefit Analysis (CBA): A systematic approach to comparing the costs and benefits of a project. Benefits must outweigh costs for a project to be deemed viable.
• Net Present Value (NPV): The difference between the present value of benefits and costs. A positive NPV indicates a profitable investment.
• Internal Rate of Return (IRR): The discount rate at which the NPV of a project is zero. Projects with an IRR higher than the cost of capital are considered worthwhile. The discount rate is the rate at which future cash flows are adjusted to their present value, typically reflecting inflation, risk, etc.

Economic Indicators in the Appraisal Process

Tangible benefits present as these metrics used to assess the impact and feasibility of road projects. They include:

• Travel Time Savings: Reduction in travel time for users, leading to increased productivity.
• Vehicle Operating Cost Savings: Lower maintenance and fuel costs due to improved road conditions.
• Accident Reduction: Decrease in road accidents, enhancing safety and reducing economic losses from injuries and fatalities.

Economic Decision Criteria

These criteria help decision-makers determine whether an investment in infrastructure will generate sufficient returns to justify its costs and whether it aligns with broader economic goals and priorities. These include:

• Benefit-Cost Ratio (BCR): The ratio of total benefits to total costs. A BCR greater than 1 indicates a beneficial project.
• Economic Rate of Return (ERR): Similar to IRR, it measures the project’s profitability from an economic perspective.

Transport Costs & Benefits:

Transport costs and benefits are crucial in road appraisals. These include:

• Direct Costs: Construction, maintenance, and operation costs.
• Indirect Benefits: Intangible benefits may include improved accessibility, economic development, increased land and property values, and environmental benefits.

Investment Appraisal Tools for Roads:

Several tools are used for investment appraisals in road projects, including:

• Cost-Effectiveness Analysis (CEA): Compares the relative value (in terms of cost per unit of benefit) of achieving different strategies or interventions aimed at achieving a specific outcome, such as reducing traffic congestion or improving road safety.
• Multi-Criteria Analysis (MCA): Takes a broader perspective by considering various criteria or factors beyond just costs and benefits, including stakeholder preferences, social and environmental impacts, among others, in decision-making.

Overview of the HDM-4 Model

The Highway Development and Management Model (HDM-4) is a comprehensive software tool used globally for road investment analysis and management. It is specifically designed to assess the economic, technical, and financial aspects of road network investments over their entire life cycle. HDM-4 can evaluate various factors such as road condition, traffic volume, maintenance requirements, and the economic benefits of road projects. It helps decision-makers prioritize investments, optimize maintenance strategies, and estimate the long-term costs and benefits associated with different road infrastructure interventions.

It supports evidence-based decision-making and efficient management by analysing and producing the following:

• Lifecycle Costs and Benefits: Conducts a comprehensive analysis of all expenses and advantages associated with a road throughout its lifespan, encompassing construction, maintenance, and user-related costs.
• Performance Prediction: Utilizing current road conditions and projected traffic growth, it forecasts the future performance of roads, aiding in proactive planning and resource allocation.

Economic Analysis: Evaluates the economic viability of road projects by employing key financial metrics such as Net Present Value (NPV), Internal Rate of Return (IRR), and Benefit-Cost Ratio (BCR), providing crucial insights for decision-making and resource allocation

Case Study:

ITEC Engineering Ltd is part of a team engaged on a project by the East African Community (EAC) to conduct Feasibility and Financing Options Studies of the Multinational Kenya/Uganda: Kisumu – Kisian – Busia / Kakira – Malaba & Busitema – Busia Expressway. The purpose of economic evaluation in this context is to guide the Authorities in deciding on whether the project is sound on technical, economic, social and environmental perspectives and its overall viability.

The key scope encompasses a wide range of activities crucial for the project’s success. These include conducting a comprehensive financial and economic analysis, performing traffic studies and analysis, reviewing designs, and developing preliminary geometric designs. Additionally, assessments of pavement capacity and geometry are conducted, along with economic feasibility studies and bankability analysis. An analysis of funding options is also undertaken, alongside environmental and social impact assessments, including screening and the development of Terms of Reference (TORs). Furthermore, detailed engineering design TORs are established, and a project risk analysis is conducted to ensure a thorough and cohesive approach to project planning and implementation.

In summary, the project aims to:

1. Propose road improvements, and where necessary, upgrades of selected segments of certain existing project roads to higher operational standards, e.g. single carriageway to dual carriageways and dual carriageways to expressways, as necessary;
2. Estimate the long-term costs and benefits associated with the interventions proposed in the preliminary design; and,
3. Guide the Client on prioritizing investment on the various road sections along the project corridor.

Conclusion:

Financial and economic evaluations are the backbone of successful road infrastructure projects and shaping transportation development. By meticulously analysing costs and benefits, these evaluations guide informed decision-making and resource allocation, ensuring that investments not only enhance connectivity but also drive economic growth. As Kenya continues to expand its road network, leveraging tools like HDM-4 for holistic evaluations will be crucial in realizing sustainable and economically viable infrastructure development that align with national and regional priorities

In an era where infrastructure development is the backbone of economic progress, public-private partnerships (PPP) have emerged as a vital mechanism for addressing the complexities and financial demands of large-scale transportation projects. But why do governments increasingly turn to PPPs? What are the benefits and challenges of this approach? Let’s delve into these questions.

The Appeal of Public-Private Partnerships

Governments worldwide are under pressure to develop and maintain robust transportation infrastructure, which is essential for economic growth, social integration, and national development. However, the resources required to fund such projects both in terms of capital and expertise are often beyond the reach of public finances alone. This is where PPPs come into play.

PPPs offer a collaborative approach where the government partners with private sector entities to finance, design, build, operate, and maintain transportation projects. For governments, PPPs provide access to private capital, innovation, and efficiency, while for private companies, these partnerships open doors to lucrative investment opportunities with the backing of public sector guarantees. PPPs are not “free money,” but they can offer benefits such as better and faster completion of the project, more budgetary accountability and overall savings. At their heart, these partnerships share risk and costs of design, construction, maintenance, financing and operations.

The Benefits of PPP in Transportation Projects

• Efficient Resource Allocation: PPPs enable governments to leverage private sector expertise and efficiency in project execution. This often results in faster project completion, adherence to budgets, and enhanced service quality. For instance, in Kenya, the Nairobi Expressway, a key PPP project, demonstrates how private sector involvement can lead to the timely delivery of infrastructure that meets international standards.
• Risk Mitigation: By involving private partners, governments can distribute financial and operational risks more evenly. This risk-sharing ensures that projects are not only completed but also maintained effectively over time. The private sector’s vested interest in the success of the project often leads to better long-term outcomes.
• Innovation and Technology Transfer: Private companies often bring cutting-edge technology and innovative practices to the table, which can significantly improve project outcomes. PPPs facilitate the transfer of these technologies and practices to the public sector, boosting overall infrastructure development capabilities.
• Economic Stimulus: Transportation projects under PPPs can stimulate local economies by creating jobs, enhancing connectivity, and attracting further investments. Improved infrastructure also leads to increased productivity and reduced operational costs for businesses, fostering broader economic growth.

Challenges in Implementing PPPs

Despite the benefits, PPPs are not without challenges.

• Complex Contractual Agreements: The success of PPPs hinges on well-drafted contracts that clearly define roles, responsibilities, risk-sharing mechanisms, and performance benchmarks. Misaligned incentives or ambiguous terms can lead to disputes and project delays.
• High Initial Costs: The preparatory phase of PPP projects often involves significant costs related to feasibility studies, legal consultations, and negotiation processes. This can be a barrier for governments, particularly in developing countries where resources are limited.
• Public Perception and Political Risk: Public acceptance of PPPs can vary, especially when projects involve tolls or user fees. Additionally, changes in political leadership or policies can introduce uncertainties, potentially jeopardizing ongoing or future PPP initiatives.
• Profitability to attract investors: Green or climate resilient infrastructure, for example, may lack a direct revenue stream from rate-payers, such as water infrastructure and toll roads.

Kenya’s Experience with PPPs

Kenya has embraced the PPP model to bridge its infrastructure gap, with the Nairobi Expressway standing out as a flagship project. This 27-kilometer toll road, connecting Jomo Kenyatta International Airport to the city center, is a clear testament to the potential of PPPs in transforming urban mobility and easing congestion.

However, the journey has not been without its hurdles. Public opposition to tolling, land acquisition challenges, and the complexity of financing arrangements have all tested the resilience of Kenya’s PPP framework. Nonetheless, the successful delivery of the Expressway highlights the country’s growing competence in managing such partnerships.

Adopting standard contracts, pricing models, risk-sharing mechanisms, and clear returns frameworks could significantly boost public-private partnerships in Kenya. Historically, similar standards have been established in key sectors like housing and small businesses. A collaborative effort involving public, private, and civil society organizations will be essential.

 A promising model could comprise partnerships for Sub-Saharan Africa states. This initiative would standardize transparency, contracts, labor practices, and risk allocation, aiming to create a thriving market for infrastructure projects. By sharing details, it enables the scaling and replication of successful project finance and delivery methods.

 If successful, such a model could inspire similar exchanges in Kenya, tailored to local needs. For instance, a Kenyan infrastructure “Exchange” could focus on critical sectors such as climate resilient roads, affordable housing, water infrastructure, and energy projects, reflecting the unique challenges and opportunities within the region. Linking these exchanges through a centralized platform could facilitate the sharing of data, information, and best practices across different regions, enhancing the effectiveness and reach of infrastructure initiatives across the country.
