Validation of Automatic Vehicle Location Data in Public Transport Systems [PDF]
Electronic Notes in Theoretical Computer Science, 2015 AbstractPerformance metrics for public transport systems can be calculated from automatic vehicle location (AVL) data but data collection subsystems can introduce errors into the data which would invalidate these calculations, giving rise to misleading conclusions.

The Robust Semantic SLAM System for Texture-Less Underground Parking Lot
Journal of Advanced Transportation, 2022 Automatic valet parking (AVP) is the autonomous driving function that may take the lead in mass production. AVP is usually needed in an underground parking lot, where the light is dim, the parking space is narrow, and the GPS signal is denied.

Multi-Sensor Fusion for Lateral Vehicle Localization in Tunnels
Applied Sciences, 2022 The satellite navigation signal in the tunnel is weak, and it is difficult to achieve accurate lateral positioning in complex conditions such as low-speed congestion by relying solely on inertial navigation or line image recognition, which is one of the ...

Improving Automatic Vehicle Location Efficiency through Aperiodic Filtering [PDF]
2006 IEEE Intelligent Transportation Systems Conference, 2006 Automatic vehicle location (AVL) systems are becoming increasingly common, especially for fleet monitoring/management applications such as probe vehicle operation. A large percentage of AVL systems report position and sometimes velocity on a periodic basis to a base station. However, sending data on a periodic basis can be costly and inefficient. It is

Global positioning automatic vehicle location system [PDF]
, 1997 Los Alamos National Laboratory (LANL) is a unique facility covering over 43 square miles. The Emergency Management and Response Office (EM&R) is required to respond, provide Incident Command (IC), and coordination for all Laboratory emergencies. This requires IC`s and support staff to respond to the actual scene of the incident.

Measuring Service Reliability Using Automatic Vehicle Location Data [PDF]
Mathematical Problems in Engineering, 2014 Bus service reliability has become a major concern for both operators and passengers. Buffer time measures are believed to be appropriate to approximate passengers′ experienced reliability in the context of departure planning. Two issues with regard to buffer time estimation are addressed, namely, performance disaggregation and capturing passengers ...
