Mobility OptionsRideshare Program Operational Support;Carsharing at Priority Bus Activity Nodes;Enhanced Virginia Vanpool Insurance Pool andEnhanced Telework!VA.Based on a review of the likely effects of enhanced TDM programs and the focus of the regionaltravel demand forecasting model, it was determined that these strategies should be analyzedusing off-model techniques. More details about program specifics and the analysis can befound in the TDM portion of Section 3.2.Key FindingsA range of improved TDM strategies and programs, including marketing and outreach,vanpool programs, and financial incentives will be able to attract some new commuters toalternative modes, decreasing the SOV mode share for work trips. The success of this option isdependent on the level of investment, as detailed in Section 3.2.Option I – Bicycle/Pedestrian System EnhancementsThis mobility option includes the implementation of a range of bicycle and pedestrianimprovements of varying scales. These elements will add new connections (on- and off-road)to address gaps in the nonmotorized network in the study area. It also improves bicycle/pedestrian access to transit (bus and rail), expands bicycle parking at transit stations, andexpands the bikesharing program. Because the TPB regional travel demand forecasting modelis not sensitive to changes in the physical bicycle and pedestrian networks, this mobility wasevaluated using off-model techniques. More detail about the analysis and the proposedimprovements included as part of this mobility option can be found in Section 3.2.Key FindingsThis option includes many improvements to the pedestrian and bicycle systems designed tomake nonmotorized travel in the study area easier and more appealing. The improvements areespecially focused on improving access to Metrorail stations and encouraging more transit use.2.4 Mobility Option Summary FindingsTable 2.3 provides the detailed MOE results for each of the nine mobility options that were testedusing the regional travel demand forecasting model. The results of each option can be comparedto the results of using the CLRP+ network with the abbreviated process outlined in Section 2.2.This Baseline scenario is shown in the tables below. As previously noted, the mode choice resultsof the mobility options and the CLRP+ Baseline shown in Table 2.3 should be viewed with theunderstanding that non-congested road speeds were used as inputs to the mode choice model.Additionally, without the speed feedback to trip distribution, the results shown do not reflectany changes in travel patterns which might result from the proposed options.I-66 Multimodal Study 2-33
