From page 67... ... Develop ICM System Concept 67 • Maintenance and Construction Planning – Planned events, such as anticipated lane and roadway closures for scheduled maintenance, can be considered by freight dispatchers and fleet managers when driver plans are developed each day, such that the trip performance and delivery impacts of those closures can be minimized. Long-term freight planning data can also be used as inputs for optimizing maintenance schedules, so that closures on peak freight routes and travel days can be minimized or anticipated and mitigated.

From page 68... ... 68 Broadening Integrated Corridor Management Stakeholders • Transit Access and Intermodal Transfers – Information systems can improve the ability of riders to make intermodal transfers. For example, space availability at park-and-ride lots and transit stations can be broadcast along the corridor to help travelers select the best location to park. Read the entire page →
From page 69... ... Develop ICM System Concept 69 incidents, and other positive outcomes. – Potential benefits toward responder safety; safe, quick incident clearance; and prompt, reliable, interoperable communication objectives. Read the entire page →
From page 70... ... 70 Broadening Integrated Corridor Management Stakeholders • Pedestrian and Bicyclist-Specific Traveler Information Dissemination – Currently, traveler information disseminated through 511 systems and dynamic message signs are rarely relevant to non-motorized roadway users. Pedestrian and bicyclist-specific traveler information (e.g., impacts to non-motorized roadway users during incidents, vehicle volumes and speeds on arterials, intersection delays, high-frequency crash locations, impacts of ICM trip diversion on crash risk levels, quality of street lighting and sidewalks, etc.) Read the entire page →
From page 71... ... General Description Recurrent congestion that occurs during the same peak periods every day when traffic demand exceeds roadway capacity. No incidents (roadway, transit, arterials, weather, etc.) Read the entire page →
From page 72... ... General Description Major or minor incident affects traffic flow on at least one freeway lane. Incident potentially involves fatalities, injuries, lane closures, law enforcement actions, or hazardous materials. Read the entire page →
From page 73... ... General Description Major or minor incident affects traffic flow on at least one arterial lane. Incident potentially involves fatalities, injuries, lane closures, law enforcement actions, or hazardous materials. Read the entire page →
From page 74... ... 74 Broadening Integrated Corridor Management Stakeholders • Transit incident (Table 19) – The transit agency should take the lead in this scenario because the onboard transit operator is likely to be affected by the incident firsthand and can report the incident immediately to transit dispatchers.
