I-66 Multimodal Study Final Report - Virginia Department of ...

Multimodal PackagesOther suggested techniques include providing real-time transit, parking, and travel time informationvia dynamic message signs along I-66. This would be implemented in conjunction withretrofitting park-and-ride lots with an advanced parking management system (APMS), whichwould track parking space availability and communicate directly with the parking informationsigns.I-95/I-395 Corridor InitiativesIn the I-95/I-395 Corridor, ICM strategies are considered under four scenarios: incident management,adverse weather conditions, a special event, or as a travel demand management(TDM) strategy (to address recurring congestion to achieve a targeted modal-shift to ease congestionwithin the corridor project limits). Several ICM strategies are being studied as part ofan ongoing I-95/I-395 ICM study. The key areas of focus are:Information Sharing and Dissemination – Improving information dissemination to informusers of the network (e.g., different facilities, modes) about current conditions. Figure 3.41shows an example of displaying real-time multimodal travel information on a dynamic messagesign.Figure 3.41 Multimodal Travel Times on Dynamic Message SignsOperational Improvement of Network Junctions and Interfaces – Improving operations atlocations where facilities interface, be it freeway ramps, park-and-rides, or highway merges.Capacity and Demand Management – Short- and long-term capacity and demand can bemanaged using several tools such as Active Traffic Management (ATM) or Adaptive RampMetering (ARM) strategies based on real-time data, or through the enhancement of transitservices along the corridor. ATM strategies included are Hard Shoulder Running (HSR) andQ-Warning. Speed advisories also are planned as part of a lane control strategy, especially inareas where queue back-ups are significant.Promotion of Cross-Network Route/Modal Shifts – Improve information dissemination andinfrastructure along corridors (using Variable Message Signs, for example) to enable users tochange routes due to delays or use available alternative modes during a trip. Potential elementsto support such efforts on a highway and transit segment, include providing locationsfor information kiosks, queue warnings, and linkages to transit options.Institutional Coordination – Facilities and services within the corridor are operated by differentagencies. Strong and interfaced communication among highway and transit agencies is anI-66 Multimodal Study 3-61
