Retrofit Strategy Index

Every Retrofit Strategy currently in the Commonway System, grouped by scale: Network, Corridor, and Intersection. See How to read a retrofit strategy for what each part of a Retrofit Strategy entry covers and how it relates to the Pattern catalog.

A Pattern describes what a street should be. A Retrofit Strategy describes how to move an existing street toward one. This index lists the strategies; Patterns has the destinations.

Network level strategies

Network strategies change how an area functions as a whole, typically by restricting motor vehicle through-traffic without changing any single street's underlying topology classification.

1

Modal filtering / Low Traffic Neighborhood retrofit

RFT-NET-01
2

Superblock retrofit

RFT-NET-02
3

Barrier-crossing / network reconnection retrofit

RFT-NET-03

Corridor level strategies

Corridor strategies change a single street segment's cross-section: lane count, lane width, curb use, or surface. Most can move through the construction spectrum starting from paint and temporary materials.

1

Four-to-three lane road diet

RFT-CDR-01
2

Five-plus lane reallocation

RFT-CDR-02
3

Lane diet

RFT-CDR-03
4

One-way to two-way conversion

RFT-CDR-04
5

Parking-lane reallocation

RFT-CDR-05
6

Transit priority lane retrofit

RFT-CDR-06
7

Protected bike lane retrofit via lane-width reallocation

RFT-CDR-07
8

Protected bike lane retrofit via lane removal

RFT-CDR-08
9

Protected bike lane retrofit via parking reduction

RFT-CDR-09
10

Depaving / pavement-to-gravel conversion

RFT-CDR-10
11

2+1 road with cable median barrier

RFT-CDR-11

Intersection level strategies

Intersection strategies change how a single intersection controls conflicting movements. Several of these require real construction from the outset and can't be meaningfully piloted with temporary materials.

1

Signal-to-roundabout conversion

RFT-INT-01
2

Median U-Turn (MUT) retrofit

RFT-INT-02
3

Restricted Crossing U-Turn (RCUT) retrofit

RFT-INT-03
4

Displaced Left-Turn (DLT) retrofit

RFT-INT-04
