In preparation for the 1984 Olympics, Los Angeles wished to enhance site visitors move and make shifting across the metropolis simpler for athletes and guests. To attain that, the town developed the Automated Visitors Surveillance and Management System, or ATSAC for brief. The aim? Transfer site visitors extra “dynamically” by synchronizing alerts and altering sign timing primarily based on site visitors patterns, so drivers had a extra predictable, smoother expertise.
Again within the Nineteen Eighties, Los Angeles, the state of California and your complete nation used an idea known as “stage of service” to evaluate transportation tasks. If somebody wished to construct a brand new condominium constructing, or if the town was contemplating a brand new crosswalk, the affect to the extent of service to drivers was measured. The aim was to have an “A” stage of service, which meant free-flowing site visitors, with out bottlenecks or gridlock. Tasks that will have slowed site visitors — even when they may encourage somebody to journey exterior of a automotive — had been usually killed within the identify of driver comfort.
There was a tradeoff to “stage of service” considering: As a result of automotive motion was so prioritized, motion for everybody else was deprioritized. Pedestrians had been made to attend a very long time to cross a road in the event that they occurred to reach simply after the sunshine modified. Cyclists had nearly no devoted infrastructure, as a result of a devoted bike lane would possibly gradual drivers down or cut back lanes or parking obtainable to drivers. And transit riders usually discovered their buses sharing lanes with folks driving personal automobiles, although a devoted bus lane can be rather more environment friendly.
At present, ATSAC — the most important system of its type within the nation — largely stays the identical because it was again within the Nineteen Eighties. Whereas we’ve added extra detector loops and cameras to measure car site visitors, the aim largely stays the identical: transfer as many automobiles as shortly as doable.
Synchronized site visitors alerts, whereas sounding interesting to drivers, aren’t at all times of their finest curiosity. When drivers see a bunch of inexperienced lights in a row on streets constructed like highways (most main streets within the metropolis of Los Angeles), they usually pace down them, typically with lethal outcomes. Dashing, the truth is, has gotten worse because the COVID pandemic.
Our metropolis has developed considerably because the early Nineteen Eighties. We now have a shortly rising Metro rail system, an increasing community of bus-only lanes and a small however rising community of motorbike lanes. Briefly, we’ve moved from a car-dominated metropolis to a extra multimodal metropolis.
The site visitors lights simply haven’t stored up. Town ought to align ATSAC with our bigger targets of serving to folks use automobiles much less, particularly for shorter journeys, and to get to and from Metro stations with out utilizing a automotive in any respect (known as “first/final mile”). Extra folks would stroll extra locations if alerts responded shortly once they pushed a button to cross the road. Angelenos can be extra seemingly to make use of a motorcycle to get round if we had a community of protected bike lanes that included sensors and responsive alerts (equivalent to what Santa Monica has carried out). Extra folks would use the bus if it had precedence at intersections and obtained to its vacation spot sooner than personal automobiles; a living proof is the G (Orange) Line within the San Fernando Valley, the place the bus runs on a devoted right-of-way however usually stops at purple lights so automobiles can cross.
It simply is sensible for our site visitors mild system to prioritize pedestrians and cyclists over motorists. Half the 12 months, it’s blazing scorching in Los Angeles, but our site visitors mild system favors those that are comfortably resting in steel bins with air-con. The opposite half of the 12 months, it’s colder (and, if this previous winter is any indication, usually raining), and but site visitors alerts nonetheless err on the aspect of motorists quite than the vacationers who’re uncovered to the weather.
In a rethought method to site visitors alerts, we must always have extra intersections with scramble crosswalks, the place pedestrians can cross freely in all instructions directly, whereas automobiles are utterly stopped. We’d like extra intersections with devoted bike bins (and bike alerts) that prioritize these strolling and biking (equivalent to the one on Rosewood at La Brea).
Throughout the town, we have to change our alerts to be free working, that means they react shortly to demand or change on a schedule as a substitute of making an attempt to synchronize and provides drivers a protracted runway to hurry. We used schedules early within the pandemic at practically all alerts, so folks didn’t have to the touch pedestrian crossing buttons — so this isn’t a tough change to think about or institute.
If Los Angeles is severe about its residents strolling, biking and utilizing transit extra, then it must get severe about prioritizing these various modes of transportation. That is very true for shorter journeys — and 50% of outings that People (together with Angelenos) make every day are three miles or much less. We’d like intersections that reward residents for not utilizing a automotive. Whereas optimizing car site visitors move is necessary, optimizing our site visitors mild system for the move of individuals is extra necessary.
