METHODOLOGY
An off-the-shelf microscopic simulation tool with advanced programming interface capabilities was selected to support the development and assessment of TOSCo functionality. Performance…
Methodology
Changes in average speeds, travel times and various travel time reliability measures along the corridor were quantified using a before-after comparison. Incident clearance and special…
METHODOLOGY
A microscopic traffic simulation model of Ann Arbor was developed along with an adaptive traffic signal control algorithm to investigate the energy savings and mobility benefits…
The introduction of autonomous vehicles to the "commute trip sharing problem" (CTSP) was found to serve, on average, an order of magnitude more trips than conventional vehicles. While implementing…

Conclusions and lessons learned from this project are as follows:
The TRP on-bus software was effective at providing alerts to transit drivers.
The transit drivers expressed acceptance of the TRP…
Installation and use of Automatic Vehicle Location (AVL) technology can greatly enhance transit agency performance. Operations and emergency response are enhanced, operational data can be captured to…
Active traffic management (ATM) aims to dynamically manage recurrent and non-recurrent congestion based on prevailing and predicted traffic conditions. Researchers analyzed the effectiveness of the…
This article referenced cost data from an autonomous robot delivery operator in Ann Arbor, Michigan.
Cost of delivery using a robot: $2.00 to $2.50 per package
Cost of delivery using a human: $11…
In 1997, the Ann Arbor Transportation Authority, in Ann Arbor, Michigan, implemented an advanced public transportation system for its fixed route and paratransit bus operations. The system integrated…
