This paper presents a policy-level financial evaluation of options to mitigate congestion on metropolitan freeways where expanding capacity is difficult due to cost or environmental constraints. The options involve converting general-purpose lanes to priced High-Occupancy/Toll (HOT) lanes in combination with incentivized ridesharing. We estimate the financial impacts on a hypothetical 6-lane freeway (i.e., with 3 lanes per direction). The results of the analysis suggest that the options can generate sufficient revenue to support operations and may also generate surplus revenues to fund capital costs.

将现有的通用车道转换为高占用率/收费车道：探索性评估

本文提出了一种政策层面的财务评估，以缓解因成本或环境限制而难以扩大容量的大都市高速公路拥堵。这些选项包括将通用车道转换为高占用率/收费 (HOT) 车道，并结合激励性拼车。我们估计了假设的 6 车道高速公路（即每个方向 3 车道）的财务影响。分析结果表明，期权可以产生足够的收入来支持运营，也可能产生盈余收入来支付资本成本。
