The methodology to measure the performance of urban streets was significantly revised in the latest edition of the Highway Capacity Manual (HCM 2010). This paper describes concerns expressed in the literature with HCM 2010’s urban streets methods and describes the development of a new, alternative method that addresses the following: (1) the use of level of service (LOS) step functions; (2) the comparability of LOS results across modes; (3) the impacts of modes on other modes; (4) the establishment of thresholds; (5) accuracy; and (6) user perceptions in measuring multimodal conditions on urban streets. The findings of the literature review were considered, and attempts were made to address them in the development of the alternative method. Feedback relating to the findings of the literature review and key elements of the alternative method developed was gathered from four panels of practitioners. Practitioners supported the key aspects of the alternative method and recommended using such a method in addition to the HCM 2010 urban streets methods. Panel members also made recommendations for improving the HCM 2010 urban streets methods.
