Akcelik SIDRA Intersection is an advanced micro-analytical traffic evaluation tool that applies the methodology from the Austroad’s Guide to Traffic Management (AGTM) and incorporates Professor Rahmi Akçelik’s internationally recognized models. It is used worldwide for detailed assessment of intersection performance, including calculations of delays, queue lengths, fuel consumption, emissions, and economic costs (crash risk, vehicle operating costs). The software is essential for optimizing signal timings, evaluating intersection layouts, and conducting before-and-after studies for transportation projects.
Akcelik SIDRA Intersection 2025 v10.0.6.236 is a specialized traffic analysis software designed for Transportation Engineers, Traffic Planners, Intersection Designers, Traffic Signal Engineers, Transit Planners, and Consultants who need to analyze the capacity, level of service (LOS), and performance of signalized and unsignalized intersections, roundabouts, and interchange ramps.
Comprehensive Intersection Analysis: Models a wide variety of intersection types: signalized intersections (fixed-time, actuated), roundabouts (single and multi-lane), all-way stop signs (AWSC), two-way stop signs (TWSC), and interchange ramp terminals.
Advanced Lane-Based Methodology: Employs a detailed lane-by-lane and movement-based analysis, accounting for lane utilization, shared lanes, flared approaches, and short lanes.
Detailed Output & Performance Measures: Calculates key performance indicators (KPIs) such as degree of saturation, control delay (seconds/vehicle), queue lengths (95th percentile), stops, fuel consumption, and CO2 emissions.
Signal Timing & Optimization: Includes tools for developing and optimizing multi-phase traffic signal timings (cycle length, green splits, offsets) and evaluating coordinated signal systems (green bands).
Network Analysis (SIDRA Trips): Ability to model trip patterns and analyze small to medium-sized networks of interconnected intersections.
Calibration & Scenario Comparison: Allows calibration of key model parameters to local conditions and facilitates easy comparison of multiple design or signal timing scenarios.
This annual release incorporates updated methodologies, enhanced user experience, and new analysis features.
Updated Analytical Models: Incorporates the latest research and revisions to the underlying capacity, delay, and emission models, particularly for roundabouts and signalized intersections.
