Draft Mobility Design Toolbox(a living document)
DRAFT 7.10.19 River Street Reconstruction Mobility Toolbox – Slide 1
Introduction• This Mobility Design Toolbox was created as a reference for the River Street
Reconstruction project. More information about the project, and a similar Streetscape Design Toolbox document can be found on the River Street Reconstruction web page, http://cambridgema.gov/riverstreet
• This toolbox is a reference for the types of design treatments that could be considered to address transportation opportunities and challenges on River Street. It is not intended to propose specific design solutions.
• It is intended to be a work in progress, or a living document, that can be refined throughout the River Street Reconstruction design process.

DRAFT 7.10.19 River Street Reconstruction Mobility Toolbox – Slide 14
Involves extending the green time at an
intersection or calling the green time early
for the approach that a bus is traveling on.
This may or may not involve a dedicated
lane or queue jump.
1. On-board technology requests signal priority.
2. In addition, in ground technology like loop detectors can detect when buses approach a signal.
3. The request is received and processed by traffic equipment or through a centrally controlled system
