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

Mobility Options2.0 Mobility OptionsSection 4.0 of the Interim Report, Evaluation Methodology, provides the overall decisionmakingframework used to address the issues and needs identified in the I-66 corridor. Theevolution from mobility option elements to mobility options is an important step in developingalternatives, known as multimodal packages, for the I-66 corridor.2.1 Approach to Selecting Mobility OptionsDefinition of Mobility OptionsThe issues and needs and mobility option elements serve as the basis for formulating mobilityoptions. The issues and needs were developed based on the findings of a transportation andland use systems analysis, as well as stakeholder input and Lead Agency and ParticipatingAgency Representatives Committee (PARC) input. The comprehensive set of transportationissues and needs identified for the study area are as follows:1. Westbound roadway congestion;2. Eastbound roadway congestion (including interchange capacity constraints at the DullesConnector Road);3. Capacity issues at I-66/arterial interchanges;4. Non-HOV users during HOV operation hours;5. Orange Line Metrorail congestion;6. Adverse impact of roadway congestion on bus service;7. Challenges to intermodal transfers (rail, bus, bicycle, car);8. Bottlenecks on W&OD and Custis Trails; and9. Limitations/gaps in bicycle and pedestrian accessibility and connectivity.Defining the mobility option began by comparing the issues and needs against potential solutions.Some issues and needs can be grouped together to reflect overlaps in potential implementationactions. Potential solutions were grouped into logical implementation actions thatall support a single need or group of needs. A visual representing this transition is presented inFigure 2.1.The identification and development process of formulating mobility options was initiallyinformed by market research, stakeholder interviews, previous studies, the technical studyteam, and members of the PARC. The translation from issues and needs to potential mobilityoptions is based on an organization of the issues and needs aligned with potential solutions.2-1
