SacCity street design for transit

Part of an ongoing series of posts to support better streets in the City of Sacramento during their 2023 update of Street Design Standards. New standards must be innovative, safe, and equitable, and it will take strong citizen involvement and advocacy to make them so.

The purpose of designing streets for transit is to actively shift trips away from private motor vehicles and to transit. Most arterial streets in the city should have dedicated bus rapid transit design, and any street with more than one general purpose lane per direction should have a dedicated bus lane, with red paint.

  • Transit Street Design Guide will be used along with close collaboration with the transit agency to determine optimal and innovative street designs supportive of transit
  • Dedicated bus lanes will be provided on all 15-minute frequency bus routes on streets over one lane per direction
  • Light rail will be given exclusive right-of-way on streets with three or more lanes existing; and considered for streets with two or more lanes existing
  • Bus bays which force buses to pull out of and into traffic will not be used, except where the transit agency has identified the need to wait for a timed stop or to layover
  • Curb extensions may be lengthened to provide in-lane bus boarding
  • Dedicated bus lanes shared with bicyclists will be used only when high quality bicycle facilities on an immediately parallel street are not available, or to solve right-of-way issues of one block or less
  • Bus routes with 15-minute or better frequency, and light rail, will have transit signal priority at all intersections

Design diagrams will be developed in cooperation with the transit agency:

  • Bus stops, including stop amenities, with preservation of sidewalk passage
  • Concrete bus pads to lessen pavement deterioration
  • Bus boarding extensions on streets without bike facilities
  • Bus boarding islands with bicycle facilities behind, including design features that slow bicyclist traffic behind the island to prioritize walkers
  • Raised platforms for low floor or level boarding of light rail vehicles
  • Bus rapid transit streets, including potential raised platforms

We need more of this… dedicated bus lanes

The recent relocation of bus service from L Street to the Capitol Mall for demolition of the mall and later construction of the arena has resulting in an interesting change: the first dedicated bus lane (that I’m aware of) in the Sacramento region. There are some dedicated light rail lanes.

True, the bus lane is only one block long, between 8th Street and 7th Street (this photo is taken from 8th Street looking westbound).

Prior to the bus stops being moved, asphalt was replaced with concrete, which is the only material that can stand up well to frequent bus traffic.

So why am I excited about a one-block long dedicated bus lane? Because it is a local example of something that is happening in many cities, but you don’t have to travel to see it. It also represents a reallocation of street space that increases the utility of bus systems and better balances different modes of transportation. Buses spend much of their time at critical times of the day waiting on motor vehicle traffic congestion. Dedicated bus lanes remove some of this conflict and create, for the first time, the possibility of buses being a faster mode of transport than private cars.

This one-block location show a good balance of modes. There is a wide sidewalk for pedestrians, a dedicated bus lane, a dedicated bicycle lane, and a travel lane for motor vehicles. Many more of our streets should look like this. Any street that carries bus traffic at a frequency of once every ten minutes or better (whether from a high-frequency single route or from multiple routes), at any time of day, should have dedicated bus lanes.

There are six SacRT routes that ran on L Street and are temporarily running on Capitol Mall. In addition, four Yolobus routes and several from other transit providers run along these streets.

So what are we going to do when the arena is finished and some or all of the bus traffic moves back to L Street? I think that L Street should have a dedicated bus lane from 15th Street, where it becomes three lanes westbound (and four lanes at 6th Street), all the way to 3rd St. SABA has suggested a protected bike lane on the south side for the portion between 7th Street and 3rd Street, and I think that is a good idea as well. I am not sure if SacRT has proposed anything. Wide sidewalks, dedicated bus lanes, protected bike lanes, and a somewhat reduced capacity for private motor vehicles would make for a more welcoming and efficient street. The arena developers and city have resisted making any transformative changes to circulation downtown, but significant public pressure could bring the improvements.

The NACTO Urban Street Design Guide has diagrams and details about dedicated bus lanes.
