¿Cuáles son las tendencias e innovaciones actuales en la sincronización y coordinación de señales de tráfico?

Apart from SCOOT and SCATS, MOVA (Microprocessor Optimised Vehicle Actuation) is also an vehicle actuated signal control. However, this is more suitable for isolated junctions and small linked networks. MOVA has two modes of operation: 1. Delay minimizing under normal mode of operation and 2. Capacity Maximizing when the junction approaches the its capacity to get the maximum traffic through the junction.

Adaptive signal control systems like SCOOT and SCATS indeed represent significant advancements in traffic management. SCOOT (Split Cycle and Offset Optimization Technique) and SCATS (Sydney Coordinated Adaptive Traffic System) are widely recognized as some of the leading solutions in this field. Both systems leverage real-time traffic data to dynamically adjust signal timings, optimizing traffic flow and reducing congestion.

Current trends and innovations in traffic signal timing and coordination include: 1. Adaptive Signal Control Technology (ASCT): Signals adjust in real-time based on traffic conditions to optimize flow and reduce delays. 2. Artificial Intelligence (AI): Machine learning models analyze traffic patterns and predict demand for better signal timing. 3. Connected Vehicle Integration: Vehicles communicate with signals to anticipate traffic conditions and reduce stop times. 4. Pedestrian and Bicycle Prioritization: Smart signals give priority to non-motorized road users for safer crossings. 5. Eco-Traffic Signal Timing: Reduces fuel consumption and emissions by optimizing stop-and-go cycles.

Transit Signal Priority (TSP) is a system that enhances the movement of public transit vehicles, like buses and trams, through signalized intersections. Key aspects include: 1. Signal Preemption: Transit vehicles approaching an intersection can extend the green light or shorten the red light to minimize delays. 2. Detection Technologies: GPS, sensors, or radio transmitters are used to detect transit vehicles and communicate with the traffic signal system. 3. Selective Priority: TSP is often activated based on criteria such as schedule adherence, vehicle occupancy, or congestion levels. 4. Integration with Adaptive Systems: TSP works alongside adaptive signal control to balance transit priority with general traffic flow.

This can be seen in NCHRP Report 969. On a whole, other options for timing for other users can involve different performance metrics. Looking at more than peak hour capacity, vehicular delay, and Level of service, and looking at metrics such as 24 hour capacity, Pedestrian LOS, Pedestrian Delay, Transit LOS/delay, and more! This can change what signal timings are chosen and what is ultimately selected - just by assigning and monitoring more than just vehicular performance metrics.
