Simtraffic 6
SimTraffic, the powerful, easy-to-use traffic simulation software.
SimTraffic is a revolutionary development in the Traffic Engineering field. The program makes powerful simulation and animation easy and fast enough for everyone to use.
SimTraffic includes the vehicle and driver performance characteristics developed by the Federal Highway Administration for use in traffic modeling. The underlying formulas represent over 20 years of research into traffic modeling.
Synchro 6
Synchro 6 is a complete software package for modeling and optimizing traffic signal timings.
Capacity Analysis
Synchro implements the Intersection Capacity Utilization (ICU) 2003 method for determining intersection capacity. This method compares the current volume to the intersections ultimate capacity. The method is very straightforward to implement and can be determined with a single page worksheet.
Synchro also implements the methods of the 2000 Highway Capacity Manual, Chapters 15, 16, and 17; Urban Streets, Signalized Intersections, and Unsignalized Intersections. Synchro provides an easy-to-use solution for single intersection capacity analysis and timing optimization.
Synchro 6 now includes a term for queue interaction blocking delay. A new Total Delay will include the traditional control delay plus the new blocking delay. Delay calculations are an integral part of the optimization ive in Synchro so this will be directly considered.
In addition to calculating capacity, Synchro can also optimize cycle lengths and splits, eliminating the need to try multiple timing plans in search of the optimum.
All values are entered in easy-to-use forms. Calculations and intermediate results are shown on the same forms.
If the intersection is coordinated, Synchro explicitly calculates the progression factor. With the Highway Capacity Software (HCS), it is necessary to estimate the effects of coordination. Synchro calculates the effects of coordination automatically and accurately
Coordinate and Optimize
Synchro allows you to quickly generate optimum timing plans. Synchro optimizes the split, cycle length, and offsets. Synchro optimizes to reduce delays and stops.
Synchro is fully interactive, when you change input values, the results are updated automatically. Timing plans are shown on easy to comprehend timing diagrams.
Actuated Signals
Synchro provides detailed, automatic modeling of actuated signals. Synchro can model skipping and gapping behavior and apply this information to delay modeling.
Time-Space Diagram
Synchro has colorful, informative Time-Space Diagrams. Splits and offsets can be changed directly on the diagram.
Synchro features two styles of time-space diagrams. The bandwidth style shows how traffic might be able to travel down an entire arterial without stopping. The vehicle flow style shows individual vehicles that stop, queue up, and then go. The traffic flow style gives a much clearer picture of what the traffic flow actually looks like.
Time-space diagrams can be printed using any Windows compatible printer.
The Time-Space diagrams also shown queue interaction problems with color coded bars near the intersections.
CORSIM and HCS
Synchro features preprocessors to these popular software analysis packages.
Enter data once with easy-to-use Synchro, and then perform analyses with the industry standard, legacy software
