I-495 and I-270 Managed Lanes Study
The I-495 and I-270 Managed Lanes Study
The purpose of the I-495 and I-270 Managed Lanes Study is to develop a travel demand management solution that addresses congestion, improves trip reliability on I-495 and I-270 within the study limits and enhances existing and planned multimodal mobility and connectivity. MDOT SHA intends to utilize a public-private partnership (P3) in order to design, construct, finance, operate and maintain any proposed infrastructure improvements.
Prince George’s County Planning Department and Prince George’s County Department of Parks and Recreation are reviewing MDOT SHA’s Purpose and Need Statement for the I-495 and I-270 Managed Lanes Project. As stewards of the natural and built environment, and as a cooperating agency on this project, as identified as such by SHA, Prince George’s Planning and Parks Department’s are working to assess the goals, objectives, and criteria from a land use perspective.
Managed lanes are an option to provide travelers with a choice of single-occupant vehicle (SOV) travel in specific areas of roadways. Any selected build alternative is likely to have significant effects on parkland and the associated facilities, programs and natural and cultural resources in both counties as well as significant community impacts. In order to address the impact of the alternatives, the Managed Lanes Study will ultimately evaluate the impact to properties and resources based upon the Alternatives Retained for Detailed Study (ARDS) as a result of the public input based on criteria outlined in the Purpose and Need Study. The magnitude of the impacts will be evaluated by M-NCPPC staff, and required mitigation proposed by MDOT SHA will ultimately be presented to the M-NCPPC as the project progresses.

What are Managed Lanes?
Managed Lanes are defined as highway facilities or a set of lanes where operational strategies are proactively implemented and managed in response to changing conditions.
Priced Managed Lanes
combines two highway management tools:Congestion Pricing:
The use of pricing moderate demand during peak periods is common in sectors such as power and air travel. Similarly, the concept of value pricing within the highway sector involves the introduction of road user charges that vary with the level of congestion and/or time of day, providing incentives for motorists to shift some trips to off-peak times, less congested routes, or alternative modes. Higher prices may also encourage motorists to combine lower-valued trips with other journeys or eliminate them entirely. When peak-period volumes are high, a shift in a relatively small proportion of trips can lead to substantial reductions in overall congestion levels and more reliable travel times.Lane Management:
The rationale for lane management is to maintain a superior level of service and provide an alternative to general-purpose lanes during peak travel periods. Lane management involves restricting access to designated highway lanes based on occupancy or vehicle type. By limiting the number of vehicles in designated lanes, it is possible to maintain a desirable level of traffic service. Managed lanes are separated from general-purpose lanes, it is possible to maintain a desirable level of traffic service. Managed lanes are separated from general-purpose lanes by differentiating pavement striping or physical barriers, with entry often but not always limited to designated locations.Information obtained from Slide 14 – Transportation Terminology
