Prince Abdullah Bin Abdulrahman Road and Adjacent Street Upgrade Project, Saudi Arabia

Project Introduction

The Prince Abdul Rahman Road Traffic Corridor Study focuses on improving a 4km arterial road in Riyadh, Saudi Arabia. Located within the Diriyah Gate Development Authority Supervisory Area (DGDA-SA), the corridor connects Al-Shaikh Mohammad Ibn Abdalwahab Street and Al Shaikh Mohammad Ibn Ibrahim Street. The road serves as a main collector and requires upgrades to standardize design and ensure adequate traffic capacity. Traffic data from 2023 was analyzed to evaluate the operational performance of 14 junctions along the corridor. The study aimed to enhance traffic circulation and meet the development goals of the DGDA.

Challenges

Challenges included collecting traffic and parking data during school holidays and working days, revealing variations in traffic patterns. Traffic analysis was conducted for base, opening, and horizon years across AM, midday, and PM peak hours. The evaluation also involved comparing two improvement scenarios: a Two-way Option and a One-way Option.

Solution

Comprehensive traffic surveys and growth projections informed reliable volume estimates for all scenarios. Analysis identified the Two-way Option as the recommended solution due to better operational performance. Proposed improvements addressed capacity constraints, enhanced traffic circulation, and aligned with DGDA standards. The final findings were compiled into a Traffic Study Report and presented to local authorities. These solutions aim to ensure the corridor’s efficiency and support future growth in the area.
