Download Synchro plus SimTraffic 12.2 – Advanced Traffic Signal Timing and Microscopic Traffic Simulation Software

Synchro plus SimTraffic 12.2 is an integrated software suite developed by Trafficware, a Siemens company, designed for traffic engineers and urban planners. This comprehensive solution provides advanced tools for both analytical traffic signal timing and microscopic traffic flow simulation, enabling professionals to optimize traffic operations and visualize network performance. It is a critical application for the civil engineering and transportation planning sectors, aiming to enhance traffic flow efficiency and safety.

Comprehensive Traffic Signal Timing with Synchro

Synchro forms the analytical core of the software suite, focusing on the precise optimization of traffic signal operations. It employs methodologies aligned with the Highway Capacity Manual (HCM) to determine optimal signal parameters. Key functions include the calculation of signal cycle lengths, the distribution of green time (splits), and the synchronization of adjacent signals through carefully calculated offsets. This enables engineers to develop coordinated timing plans designed to minimize vehicle stops and reduce overall network delays.

Realistic Traffic Flow Simulation Using SimTraffic

SimTraffic complements Synchro by providing a powerful microscopic traffic simulation engine. It models individual vehicle movements and driver behaviors, such as lane changing, gap acceptance for turns, and acceleration/deceleration characteristics, on a vehicle-by-vehicle basis. This detailed approach allows for the creation of realistic traffic flow scenarios. The software includes pedestrian movement simulation capabilities and generates animated visualizations of traffic networks, which are invaluable for communicating complex traffic dynamics and operational impacts to stakeholders.

Seamless Integration: From Analytical Models to Simulation Validation

The strength of Synchro plus SimTraffic lies in its integrated workflow, which bridges analytical signal timing with dynamic simulation. Users can develop traffic signal timing plans in Synchro and then seamlessly transfer them to SimTraffic for validation without manual data re-entry. This synchronized execution allows for direct comparison of performance metrics (Measures of Effectiveness – MOEs) between analytical predictions and simulation outcomes. The suite facilitates the efficient creation and comparison of multiple operational scenarios, supporting robust decision-making.

Innovations in Traffic Simulation: 3D Visualization & Connected Vehicle Modeling

Recent advancements in Synchro plus SimTraffic 12.2 introduce sophisticated features to address evolving traffic management needs. The software now offers enhanced 3D visualization capabilities, providing a more immersive and intuitive representation of traffic networks and their operations. Furthermore, it incorporates modeling functionalities for connected and automated vehicles (CAV), allowing traffic engineers to assess the potential impacts of these emerging technologies on traffic flow, intersection performance, and signal timing strategies within a simulated environment.

Applications in Traffic Engineering and Urban Planning

Synchro plus SimTraffic is applied across a wide range of real-world traffic engineering challenges. Its capabilities are instrumental in optimizing signal coordination along arterial corridors to improve traffic flow and reduce congestion. Engineers use the software for detailed intersection capacity analysis (evaluating Level of Service – LOS), managing queue lengths, and mitigating bottlenecks. The simulation outputs also serve as crucial evidence for justifying proposed traffic management strategies and infrastructure projects to planning commissions and the public.

Output and Reporting for Effective Decision-Making

The software generates comprehensive reports to support analysis and decision-making. These outputs include HCM-style intersection summary reports detailing key performance indicators like delay and queue lengths, as well as coordination diagrams illustrating signal timing progression along an arterial. SimTraffic provides extensive simulation statistics and graphical representations of traffic flow, delays, and stops, offering granular insights into network performance under various conditions.
