Quote of the Week

“But now online navigation apps are in charge, and they’re causing more problems than they solve. The apps are typically optimized to keep an individual driver’s travel time as short as possible; they don’t care whether the residential streets can absorb the traffic or whether motorists who show up in unexpected places may compromise safety.”

Jane Macfarlane in IEEE Spectrum discussing the problem with navigation apps and why they are in many ways making traffic worse, not better.

Your Navigation App Is Making Traffic Unmanageable
The proliferation of apps like Waze, Apple Maps, and Google Maps is causing chaos



By Jane Macfarlane

Miguel Street is a winding, narrow route through the Glen Park neighborhood of San Francisco. Until a few years ago, only those living along the road traveled it, and they understood its challenges well. Now it’s packed with cars that use it as a shortcut from congested Mission Street to heavily traveled Market Street. Residents must struggle to get to their homes, and accidents are a daily occurrence.

The problem began when smartphone apps like Waze, Apple Maps, and Google Maps came into widespread use, offering drivers real-time routing around traffic tie-ups. An estimated 1 billion drivers worldwide use such apps.

Today, traffic jams are popping up unexpectedly in previously quiet neighborhoods around the country and the world. Along Adams Street, in the Boston neighborhood of Dorchester, residents complain of speeding vehicles at rush hour, many with drivers who stare down at their phones to determine their next maneuver. London shortcuts, once a secret of black-cab drivers, are now overrun with app users. Israel was one of the first to feel the pain because Waze was founded there; it quickly caused such havoc that a resident of the Herzliya Bet neighborhood sued the company.

The problem is getting worse. City planners around the world have predicted traffic on the basis of residential density, anticipating that a certain amount of real-time changes will be necessary in particular circumstances. To handle those changes, they have installed tools like stoplights and metering lights, embedded loop sensors, variable message signs, radio transmissions, and dial-in messaging systems. For particularly tricky situations—an obstruction, event, or emergency—city managers sometimes dispatch a human being to direct traffic.

But now online navigation apps are in charge, and they’re causing more problems than they solve. The apps are typically optimized to keep an individual driver’s travel time as short as possible; they don’t care whether the residential streets can absorb the traffic or whether motorists who show up in unexpected places may compromise safety. Figuring out just what these apps are doing and how to make them better coordinate with more traditional traffic-management systems is a big part of my research at the University of California, Berkeley, where I am director of the Smart Cities Research Center.

1. My app gives me a choice of a couple routes based on time to drive. Then I select one.

I am not forced to drive any of them.

It also tells me what congestion there is by coloring the route red in the congested area.

So it actually relieves congestion because drivers using it avoid the red routes.

2. It's been my casual and unscientific observation that

people who depend on Navigation apps tend to take longer getting somewhere, haven't a real clue where they are most of the time, and have no overall sense of the roads.

I understand that not everyone is very good at reading maps, but most people can do so. It's the never looking at the map in the first place that seems to me to be the problem. I always look at maps. I have them in my car. Thank you, AAA. The last time I got "lost", meaning I took a wrong turn along the way and wound up taking thirty miles longer to get to my destination, was about four years ago.

I'll match my map-reading skills against your app any day of the week.
