Leveraging Communications Technologies for Transit On-board Integration

This slide, entitled "Module 23: Leveraging Communications Technologies for Transit Onboard Integration" has a graphic showing a bus at a 45 degree angle, with the back of the bus toward the top of the slide and the front of the bus toward the bottom of the slide. Above the middle of the bus is a yellow circle in which the words "Mobile IoT Gateway" (IoT meaning Internet of Things) are written along with a graphic of an on-board mobile gateway router (MGR), which will be defined in Learning Objective 2. Several items are shown connected to this yellow circle. The first is a grey circle that contains a graphic of a satellite with the abbreviation AVL just below the satellite, and is connected to the yellow circle with a black line. The second is a graphic of the bus operator and is connected with a line with an arrow at both ends. To the right of the driver are the words "Enhanced Operator Functions." The third is two grey circles, one with the graphic of a video camera and the words "Live Video" under the camera graphic, and the other with a graphic of two bus passengers with the abbreviation "APC" under the graphic of the passengers. The words above the two grey circles are "Edge Computing Analytics." The yellow circle is connected to these two grey circles with a line with an arrow at both ends. The fourth is a grey cloud with five graphics inside of it – tools; two circular lines – one at the top of a circle with an arrow pointed in a counterclockwise direction and the other at the bottom of a circle with an arrow pointed in a counterclockwise direction; a bar graph with an x and y axis; a stopwatch and a triangle with an exclamation point inside of it. Above these five graphics are the words "Cloud Services." The yellow circle is connected to the cloud graphic with a line with an arrow at both ends. Two graphics are connected to the cloud graphic. One item is two graphics – a person on a bicycle and a person riding a scooter – with the words "Mobility Options Integration." This item is connected to the cloud graphic with a line with arrows at both ends. The other item is two graphics – a person boarding the bus and a person standing outside of the bus – with the words "Personalized Customer Services" to the left of the two graphics. This item is connected to the cloud graphic with a line with arrows at both ends.
