The Mobility As A Service (MAAS) project is one of six forward-thinking projects that make up the Contra Costa Transportation Authority’s (CCTA) INNOVATE 680 program. This program seeks to implement a carefully curated suite of projects that, when operating together, will address corridorwide congestion, travel delays, and long-standing operational challenges along Interstate 680 (I-680).The MAAS project is a unique combination of public and private transportation services that will provide personalized mobility options based on traveler needs. At the core of the MAAS project is a Mobility On Demand (MOD) application or app currently under development, that will provide real-time, mutlimodal trip planning options based on origin and destination data. This app will serve up a variety of travel options based on a user’s desire for the fastest, greenest, or most cost-effective trip. The app will also include a uniform payment system and incentives based on time of day and mode in an effort to reward select travel behaviors.
