Why It Matters

Poor Traffic Planning Costs Time, Money & Safety

Developments without proper traffic impact assessments face delays, angry neighbours, and rejected permits. Inadequate junction design creates congestion and accidents. Strasan Group provides the data and analysis you need to get approvals and build roads that work for everyone.

Rejected Planning Permissions

County governments and NEMA require TIA reports for most developments. Without one, your project stalls. We deliver reports that meet all regulatory standards, so you get your permits on time.

Unsafe Junctions & Congestion

Poorly designed access points and intersections cause accidents and traffic jams. Our TIA includes junction capacity analysis and safety audits to prevent these problems before they happen.

Community Opposition

New developments often face resistance from neighbours concerned about traffic. A thorough TIA with mitigation measures shows you've considered the impact, building trust and smoothing the approval process.

Our TIA Services

Complete Traffic Impact Assessment Solutions

From initial scoping to final NEMA-compliant report, we handle every aspect of your traffic impact assessment. Our EBK-registered engineers use industry-standard software and proven methodologies to deliver actionable insights.

Scoping & Baseline Data Collection

We define the study area, identify key junctions, and gather existing traffic data. This includes 7‑day turning counts, speed surveys, and origin‑destination studies to understand current conditions.

✓ Included: Site visit & data collection plan

Junction Capacity & Safety Analysis

Using SIDRA or similar software, we analyse junction performance, queue lengths, and level of service. We also conduct road safety audits to identify and mitigate potential hazards.

✓ Included: Capacity & safety reports

Mitigation & Improvement Plans

We recommend practical solutions: junction improvements, access management, traffic signals, or roundabouts. Our plans are designed to be cost-effective and implementable.

✓ Included: Mitigation design sketches

NEMA-Compliant TIA Report

We produce a comprehensive TIA report that meets NEMA and county government guidelines. It includes all data, analysis, and mitigation recommendations, ready for submission.

✓ Included: Full report & executive summary

Public Participation & Stakeholder Engagement

We facilitate community meetings and stakeholder consultations to gather input and address concerns. This builds goodwill and strengthens your TIA application.

✓ Included: Meeting facilitation & summary

Post-Approval & Monitoring Support

We assist with conditions of approval, including traffic monitoring and implementation of mitigation measures. We can also provide expert testimony if needed.

✓ Included: Monitoring plan & expert support

FAQ

Common Questions About Traffic Impact Assessments

Here's what developers and project managers usually ask about TIA requirements in Kenya.

Is a Traffic Impact Assessment required for all developments in Kenya?

Not all, but most medium-to-large developments require a TIA. County governments and NEMA typically require TIAs for projects that generate significant traffic, such as residential estates, shopping centres, schools, and offices. We can advise on whether your project needs a TIA during a free initial consultation.

How long does a Traffic Impact Assessment take?

A typical TIA takes 4–6 weeks from scoping to final report. This includes data collection, analysis, mitigation design, and report writing. Complex projects or those requiring public participation may take longer.

What data do you collect for a TIA?

We collect turning counts, speed data, travel times, and origin-destination information. We also review existing traffic data and plans for the surrounding area.

Do you handle TIA for projects outside Kenya?

Yes. We have completed transportation studies and TIAs in South Sudan, Somalia, and Ethiopia. We are familiar with the regulatory environments and can adapt our reports to local requirements.

What does a TIA report include?

A TIA report typically includes an executive summary, existing traffic conditions, future traffic projections, junction capacity analysis, safety assessment, mitigation measures, and a conclusion. We also include appendices with detailed data and analysis.
