E-2 | MOBILITY OPTIONS Cambridge Systematics, Inc. (1) Intelligent Transportation Systems (ITS) and Transportation System Management (TSM) Strategies Strategies/Projects Traffic Signal Coordination and Modernization This strategy improves traffic flow and reduces emissions by minimizing stops on arterial streets. Enhancements to timing/coordination plans and equipment to improve traffic flow and decrease the number of vehicle stops. May include: •Modern technology that provides for real -time traffic and transit management •Equipment that may permit immediate knowledge of malfunctions •Responsive control that allows tra c signals to alter timing in response to immediate tra c ow conditions, rather tha n at predetermined times • Transit signal priority system that can extend “green - time” a few seconds to allow buses to progress through an intersection Ramp Metering This allows freeways to operate at their optimal flow rates, thereby speeding travel and reducing collisions. May include bus or high-occupancy vehicle bypass lanes. May require ramp widening to avoid extensive vehicle queuing. Highway Information Systems These systems provide travelers with real-time information that can be used to make trip and route choice decisions. Advanced Traveler Information Systems This provides an extensive amount of data to travelers, such as real time speed estimates on the web or over wireless devices, and transit vehicle schedule progress. Provides travelers with real-time information that can be used to make trip and route choice decisions. Information accessible on the web, dynamic message signs, 511 systems, Highway Advisory Radio (HAR), or handheld wireless devices. Targeted and Sustained Enforcement of Traffic Regulations Improves traffic flow by reducing violations that cause delays; Includes automated enforcement (e.g., red light cameras) . Special Events and Work Zone Management Includes a suite of strategies including temporary traffic control, public awareness and motorist information, and traffic operations . Road Weather Management Identifying weather and road surface problems and rapidly targeting responses including advisory information, control measures, and treatment strategies . Roadway Signage Improvements Adequate or additional signage that facilitates route-finding and the decision-making ability of roadway users. Signs with clearer/larger lettering that can be read from a greater distance . Dynamic Speed Control "Go Slow, Go Fast" Freeway Incident Detection and Management Systems This is an effective way to alleviate non-recurring congestion. Systems typically include video monitoring, dispatch systems, and sometimes roving service patrol vehicles. Service Patrols Service vehicles patrol heavily traveled segments and congested sections of the freeways that are prone to incidents to provide faster and anticipatory responses to traffic incidents and disabled vehicles . Converting Streets to One-Way Operations Establishes pairs of one-way streets in place of two-way operations. Most effective in downtown or very heavily congested areas . Traffic Surveillance and Control Systems Often housed within a Traffic Management Center (TMC), monitors volume and flow of traffic by a system of sensors, and further analyzes traffic conditions to flag developing problems, and implement adjustments to traffic signal timing sequences, in order to optimize traffic flow estimating traffic parameters in real-time. Electronic toll collection (ETC) Equipment that electronically collects tolls from users without requiring vehicles to stop at a toll booth . 2014 Congestion Management Process Update
