Identifying Continuous and Connected Multimodal Arterial Networks


  • The fundamentals of transportation typology and how typology and land use can be applied to inform modal priorities along arterial roadways
  • A first-of-its-kind transportation planning framework that integrates typology, land use, modal priorities, big data, multimodal performance measures and the latest in geographic information system (GIS) technology to inform multimodal arterial network needs systematically
  • Potential applications of this framework to better inform stakeholders and decision makers on multimodal infrastructure investments will also be discussed


Over the past decade, the Complete Streets movement has revolutionized transportation planning by considering how all modes use roadways collectively. While many cities have developed roadway typology to inform design of roadway improvements, these typologies do not help agencies prioritize among the needs of multimodal users. Furthermore, most typologies are prepared by individual agencies ending at jurisdictional boundaries and do not offer opportunities for continuous and connected networks across jurisdictional lines. Alameda County Transportation Commission (Alameda CTC) developed a countywide planning framework that created a typology for its 1,200 mile arterial roadway system based on two factors: land use context and modal function (transit, pedestrian, bicycle, auto, and goods movement). This framework then prioritizes the modal users on the County’s arterial roadways based on a tiering system developed from land use context and layered (or more accurately nested) modal networks. The framework applies multimodal performance measures to identify roadway segments with existing and future improvement needs for high priority modes. This needs assessment enables Alameda CTC to identify needed improvement areas or cross-jurisdictional corridor projects that would establish a system of continuous and connected multimodal networks across the county. This course will present and discuss this first-of-its-kind transportation planning framework.
