The Texas Department of Transportation (TxDOT) and the Camino Real Regional Mobility Authority (CRRMA) are constructing toll lanes in El Paso along the César Chávez Border Highway. Under the auspices of environmental justice (EJ), the toll lanes could severely impact residents in this community who live below the poverty level. TTI assessed EJ concerns in the area and offered TxDOT tolling policy options that consider the needs of the lower-income populations, while keeping in mind the need to recover bonded construction costs. TTI used a state-of-the-art simulation-based dynamic traffic assignment modeling to analyze baseline static toll rates, assess variable pricing, and model a scenario using an innovative algorithm that dynamically changes toll rates based on managed lanes’ speed to determine which option maximizes revenue. Regarding EJ issues, TTI used geographic information systems (GIS) and demographic data to identify low-income populations within the border region and mapped these to corresponding traffic analysis zones. Values-of-time were adjusted to determine how often drivers in these areas were diverting to non-tolled facilities. TTI then compared the diversion trends and assessed any potential changes in transportation service within the region. Researchers found that the César Chávez lanes should benefit income classes equitably without substantially impacting bike/pedestrian safety, air pollution, or—with noise abatement measures in place—noise pollution. Regarding modal equity—or travelers choosing a single- versus multi-occupancy vehicle mode of travel—TTI found no benefit/incentive for multi-occupant travelers unless high occupancy is considered for future operations and toll rates.
