Will Waze Carpool App Slow Down Uber?


Waze App for Carpools

Smartphones have accelerated travel information…notifications of real-time traffic, on-demand transit, and, of course, rideshare. But, can a smartphone app crack carpooling?  Waze, a Google subsidiary, developed a carpool app that will look familar to rideshare users, with features like driver name, cost, and arrival time.  Waze is now taking that app nationwide and providing incentives for new signups.

Carpooling has been the transportation “nut” that smartphones have not pried open.  In Los Angeles and most other US cities, only about eight or nine percent of commuters choose to carpool despite numerous campaigns.  I personally worked on TDM (transportation demand management) in Los Angeles and observed carpools to be the “high hanging fruit.”  (editorial  note:  nuts can be fruits)

CARPOOLS: THE HIGH HANGING FRUIT

Why?    First, the ‘real’ number of carpools is inflated and considerably less than the census numbers state. Today’s carpool count includes drivers who ride with a family member, or drop their children off at school. The drivers can legitimately say that they have a passenger, get counted in the surveys, and gain access to faster carpool lanes. But, they are not picking up a casual acquaintance or stranger.  

Carpooling can be inconvenient for a driver who might have to detour during peak-traffic to pick up or drop off passengers. It has been awkward for the driver and passenger to set a price and exchange fees.

HOW WAZE COULD HELP:

In principle, a Waze app could shift the balance.


The missing component for carpooling is the ability to establish trust between strangers.  Hitchhiking fails because strangers meet up with no prior information. An app can close the gap by providing a strongly enforced rating mechanism, like the one pushed to riders and driver after each trip on Uber or Lyft.

Prior to smartphones, there was no systematic, real-time way for riders and drivers to establish trust.  Taxi drivers were considered trustworthy because they were screened through livery boards and medallions. Limo drivers and mini-cabs in the U.K. were subject to similar checks. It is important to note that taxis, limos, and mini-cab drivers all have commercial insurance. Uber and Lyft drivers do too once they secure a passenger trip.

To establish similar levels of trust, a robust carpool app may need to certify that the driver’s DMV driving record and insurance information check-out. Then, passengers will know that they will be riding with a responsible driver in a safe vehicle.

TIME IS OF MATTER AND MORE:

Both time and distance matter for would-be carpools. Here, Waze travel information could play a crucial role. Although detouring to pick up a rider a few blocks away might seem simple there could be significant delays for the driver depending on the roads, time of day, and traffic. The algorithms used by Uber and Lyft account for these issues when they match a driver and passenger. Carpooling apps can use the same tools to minimize the inconvenience for the driver, and keep the passenger informed as the ride approaches.

Second, smartphones plus credit cards solve the monetary transaction that needs to take place between driver and passenger. The passenger does not have to “split the gas” or “share the tolls.” No cash needs to be exchanged. Having a pre-established billing system reduces the uncertainty between strangers and builds trust (#1).

Something that is exogenous,  future increase in gas prices, may serve as an incentive to carpool.  However, transportation researchers have found,  that the travel time saved by using HOV (high occupancy vehicle) lanes is also an incentive, and as more users carpool, these designated lanes became less productive.

PLUSES OR MINUSES?

That said, will the Waze app become as popular as Uber or Lyft, or will there be drawbacks?

  • Unless drivers arrange the carpool before they get in their vehicle, there will be even more reliance by  casual drivers using smartphones in traffic. Mobile phones are an increasing source of driver distraction, and there is mixed evidence, pro and con, of whether hands-free devices are safer.  Potentially, vehicle accidents could increase, but the app can help identify the safest drivers. 
  •  In a personal vehicle, the norms are fuzzy:  Some drivers may have difficulty speaking up about the house-rules and some passengers will flaunt them anyway. A carpool rating system may restore the balance, but because the rating system will be slower (a given driver makes only two or three trips a day) the driver might exit the entire system before there is an adequate feedback loop.  
  • Finally, this may be the most important reason why the carpool app will need time to grow:  “Drivers are turned inward”. The driver is transporting strangers in their personal car. For many, this vehicle is their largest purchase and most prized possession. Millions of dollars have been spent on advertising to remind car owners that “vehicles=freedom + identity + well-being.” 

So, until further notice, the decision to carpool could be overruled by the opportunity to make unannounced stops, do a drive-through for food, and have a sanctuary between the home and office.  It will just depend!

Surveys are Simple…Rideshare is Not

Imrix and Traffic
A Traffic Question

Traffic congestion is caused by many factors: population and employment growth, construction activity, deliveries, on-street parking, aggressive lane-shifting drivers, and more.

But, policy makers insist that Uber and Lyft are the primary culprits. This belief has led officials in New York City and elsewhere to propose caps on the number of rideshare vehicles,  in the name of taming congestion. 

READING THE POLLS:

Sometimes policy makers take the polls too seriously or over-interpret the results. An oft-cited poll of rideshare users in Boston, Ma. cites that 42 percent of rideshare users would otherwise use public transit. A 2017 UC Davis study of Lyft and Uber riders in seven major cities reports that fifteen percent said they would ride transit more if ride-hailing was no longer available. A separate  poll in Boston observes that 30 percent of riders have switched from transit to rideshare.  

If you unpack the surveys, there are red flags:

  1. When riders take a poll (i.e. survey) they seek a response which is socially correct and appears reasonable. It is less socially acceptable to say you would use your own vehicle and drive…it is more socially acceptable to say you would have taken the bus or train.                                                                                                                                                   
  2. Some polls fail to report the number of riders who do not currently own a car, or who have decided to postpone the purchase of one.                                                                                                                       
  3.  In most major cities, public transit operates at capacity during peak commute hours. Young people have accelerated the demand for transit because they have a lower rate of car-ownership and live close in. However, transit capacity has not expanded to meet the ridership growth.                                                                                                               
  4. Under real conditions, riders may not take the bus or train on consecutive days of the work week. The decision to ride transit on a particular day depends on multiple factors: weather, if there are kids to pick up or drop off, packages or heavy bags to tote, and the walking distance to and from the bus stop.

INFERENCES:

It is both a statistical error and a social one to infer that all of the people who said they would have used mass transit would have completed their trip that way.

There is recent data from rideshare studies that inform the issue. One of the largest increases in rideshare takes place during late evenings and weekends… times when transit service is less frequent and there are longer waits. On weekends and evenings, car owners find rideshare to be convenient for other reasons too. They can save on the cost of parking, and not worry about DUI’s.

SURVEYS ARE SIMPLE:

The thing to keep in mind is that surveys are simple…but trips are not. If someone decides to drive, instead of taking Uber or Lyft, they might “bundle” the reason for taking that trip with other interim stops. These are called “chained trips” and drivers typically complete multiple stops (or errands) on a single tour. A survey question about a single trip does not get at the nuances of chained travel, and when you ask people specifically about a single transport mode they don’t tell you why they are traveling.

The demand for trip taking is elastic, so adding capacity will encourage brand new activity patterns and travel. The convenience, reliability and low cost of rideshare has surely increased trip taking.  This observation is highlighted  in the op cit. Clewlow/Misha/UC Davis poll: 22 % say they would take fewer trips without rideshare.

NEW PLATFORM= NEW DEMAND:

However, turned around, new travel trips would also have occurred on a different platform… say public transit…if transit had become more convenient, frequent, and reliable. Unfortunately, it has not kept pace with the return of Millennials to cities and most urban systems are hobbled by network and capacity issues. The gain in more personal travel modes, like bicycles and scooters is probably indicative of underlying demand. However, these modes are not safe or practical for many potential users.  Uber and Lyft have taken up the slack.

It’s easy to point to survey results that favor transit and to scapegoat rideshare for slowing down traffic. It’s also easy for lawmakers to then proceed from survey result “A” to outcome “B” and advocacy “C”: namely, a tax or freeze on rideshare in the spirit of trying to rein it in. It is a remnant from the heady days of selling taxi medallions.

It’s harder for these survey pundits to admit that cracks in the existing transit system enabled the demand for more travel trips and hence rideshare… to spring up.
