Bus Rapid Transit (BRT) and highway expansions actually proposed for Beirut are compared using an urban computable general equilibrium model. The model has two geographic zones, central area and suburbs, but it is economically detailed. It includes production, labor, residential and commercial real estate markets and multimodal road congestion with private car, minibus and taxi vehicles and public buses. BRT reduces road congestion by 9 %, improves traffic speed by 24 %, and reduces the road congestion externality by 18 %. The BRT improves consumer utility and achieves social welfare gains that are 7.9 % of income: two-thirds are from the BRT as a new mode and one-third from the benefits of the lower congestion for the other modes. Road expansion also improves consumer utility, but achieves lower social welfare due to its cost and lower effect on real estate prices. The BRT yields an operating surplus, but road expansion requires deficit financing.

快速公交与道路扩建以缓解拥堵:一般均衡比较
使用城市可计算一般均衡模型对贝鲁特实际提议的快速公交 (BRT) 和高速公路扩建进行了比较。该模型有两个地理区域,中心区和郊区,但在经济上是详细的。它包括生产、劳动力、住宅和商业房地产市场以及私家车、小巴和出租车车辆以及公共巴士的多式联运道路拥堵。BRT减少了9%的道路拥堵,提高了24%的车速,减少了18%的道路拥堵外部性。BRT 提高了消费者效用并实现了占收入 7.9% 的社会福利收益:三分之二来自 BRT 作为一种新模式,三分之一来自其他模式的低拥堵带来的好处。道路扩建也提高了消费者效用,但由于其成本和对房地产价格的影响较小,实现了较低的社会福利。BRT 产生运营盈余,但道路扩张需要赤字融资。
