Specifications include, but are not limited to:The system must operate in field conditions experienced in the daily operation of all fleet vehicles & equipment involved in the City of Bangor’s winter maintenance operation. The types of vehicles to be supplied with Automatic Vehicle Location (AVL) units are snow plows, salt and sand spreaders, liquid deicing and anti-icing materials, sidewalk plows, patrol vehicles, and service vehicles. 1.2 The AVL control unit shall be mounted securely inside the vehicle’s cab and must operate on vehicle electric power (12V or 24V). 1.3 The antenna must be suitable for all equipment mounting (i.e. permanent or magnetic mount) and a suitable cable in varying lengths must be provided. 1.4 The system shall be able to interface to on-board discrete sensor inputs and 3rd party data logging systems (i.e. spreader controller consoles) simultaneously. 1.5 The system shall be able to interface to existing salt spreader control systems including Bosch Rexroth CompuSpread 230, 440 & 550, Cirrus. The City of Bangor currently has 2 Cirrus, 3 Bosch Rexroth 440 and 5 Bosch Rexroth 550 units. 1.6 The overall system shall be capable of tracking, storing and reporting the movements and actions of a fleet of various vehicle types in real-time. Collection of data shall include all GPS and Telematic Data being collected by the AVL unit. 1.7 Data transmission rates shall be configurable. Some fleets will require real-time reporting (every 5 seconds, 10 seconds, 30 seconds, 1 minute) while others will require less frequent updates (3 minutes, 5 minutes). System should have the ability to report on event changes and distance or a combination thereof. 1.8 Event reporting must include turn by turn reporting (i.e. 15 degree change in directional heading causes GPS data to be sent this allows corners of intersections, ramps, and other critical infrastructure to ensure there is coverage). 1.9 Positional accuracy shall be sub 2.5 meters. 1.10 The GPS receiver must be able to track coarse acquisition code and link one frequency on at least 16 parallel continuous tracking channels with an update rate to be once per second 1.11 Time to first fix shall be 35 seconds for a cold start and warm start and 1 second for a hot start for reacquisition after losing signal 1.12 The software as a service solution must have an up time of minimum 99.5%. 1.13 The system must be compatible with the City of Bangor’s browser environment. 1.14 The system must be a software as a service platform to allow for future enhancements to be deployed and configured into the system with ease. Must allow for this continuous expansion and scalability. 1.15 The system must be scalable to allow for the addition of partial or full City of Bangor fleet and allow for the management of the full fleet in a single view of the software
