Alameda Multimodal Arterial Plan

Fehr & Peers led a multidisciplinary team in the development of a first-of-its-kind Countywide Multimodal Arterial Plan for Alameda County. This plan is unique in that it relies on a quantitative, data-driven and highly technical approach to identify short- and long-term multimodal improvements along a 1,200 mile Arterial Network.

The following project components provide the technical basis for identifying a multitude of recommended improvements:

Data Collection

Readily-available data ranging from cross-sectional measurements, traffic volumes, automobile and transit speeds, pavement condition and existing collision history was collected along the Arterial Network.

Typology

The foundation framework for defining the complete streets network, which reflects how streets function for all users and establishes the connection between streets and their adjacent land uses.

Modal Priorities

The method for balancing modes along the Arterial Network, based on the typology framework and land use context.

Performance Measures and Objectives

Several measures were identified to evaluate multimodal performance; modal priorities were used to inform the performance objectives along the Arterial Network.

Fehr & Peers built a powerful GIS Tool that incorporated all project components listed above and automated the process of identifying improvements, in addition to generating cross-sectional 3D graphics that illustrate those improvements. The GIS Tool evaluated a range of potential features (preparing multiple forecasts as well as considering changes that might arise from autonomous vehicles) to identify arterial designs that respond to jurisdictional modal priorities.
