Sometimes the public expects government to see the future. Good decisions are to be expected while bad decisions — judged with the benefit of hindsight — are derided.
Some help is on the way. IBM is betting that software can give cities a better look into their future.
The company unveiled new software this week designed to help decision-makers forecast the consequences of actions that affect citizens. In turn, IBM said the software, called System Dynamics for Smarter Cities, can also help policymakers make decisions that generate positive results.
What could the software be used for?
Imagine if a city eliminated student subsidies for public transportation. The software’s analysis of results might show that a municipal transportation agency would reduce costs, thus improving its financial picture. On the other hand, because more students would bypass mass transit and instead drive themselves to school, the city might suffer more traffic congestion, worse air quality, and might be forced to deploy more first responders, said Naveen Lamba, IBM’s leader on intelligent transportation and smarter government efforts for GBS — IBM’s consulting section.
Or what if a city decided to add highway tolls where tolls previously didn’t exist?
The results could show that toll revenue could go to the coffers of agency responsible for the tolls, but could also result in less traffic congestion on the toll road, Lamba said. Fewer vehicles would improve air quality and result in more usage of public transit.
The first city to try IBM's new solution is Portland, Ore. The city used the new software to help develop a model that illustrates how the actions coming from the city’s Portland Plan — long-range sustainability goals over the next 25 years — ripple across the priority areas the city has identified, said Joe Zehnder, the chief planner for Portland’s Bureau of Planning and Sustainability.
By using the software, Portland confirmed its plan to reduce carbon emissions 40 percent by 2030 would on the whole be a positive outcome. The city had already figured in that reducing the amount of driving done in the city would encourage other modes of transportation, such as walking and biking. But city officials also appear to have discovered a positive feedback loop: More walking and biking would lead to lower obesity rates for Portlanders. In turn, a fitter population would find would find walking and biking a more attractive option.
The new software is built atop what IBM calls a “dynamic engine,” which contains 3,000 analytical equations derived from the company’s past work with cities. The system is customized for a particular city by gathering information from the city’s subject matter experts and combining it with existing government data, such as budget allocations, number of K-12 students, unemployment rates, population growth and many other indicators.
