GPS Tracking Extension Workflow

All vehicles that are equipped with AVL modems, will send their location and sensor information to MRF’s AVL data server via the cellular network. The AVL server provides the essential interface for all GPS tracking operations. MRF Web works as a portal to provide an advanced, user-friendly map interface for users to view, search and report vehicle location and operations data. There will be two data categories in the system:

  • AVL Server dataset - stores raw data sent from the AVL units.
  • GIS Application dataset - stores derived shapes for various business purposes generated from the raw AVL dataset (such as snow removal layers).

Main Interface

All the AVL functions are listed under AVL Toolbox:

Click on the Vehicle Panel button to open the vehicle list. When this panel is turned on, Legend Panel is no longer showing. User can also click on to switch between Legend Panel and Vehicle Panel.

Click on the Show/Hide Realtime Location button to view all the vehicles on map.

The main interface would look like the following:

The green arrow represents the direction of the active vehicle in real time. For example, a vehicle that has a green arrow pointing West in front indicates a vehicle is travelling West.

Real time data of vehicle state can be configured to be displayed as a map tip. In the following screenshot, the vehicle speed and timestamps were configured to show in map tips, which will automatically display when the user’s cursor is on the vehicle icon.

Vehicle Panel

Click on the Vehicle Panel button to open the vehicle list. The Vehicle Panel lists all the vehicles assigned to the current web user. User can drag the panel border to enlarge/shrink the table list for a better view:

The vehicle list is color-coded to represent the status of each vehicle.

  • Green: Online
  • Yellow: Offline
  • Red: Unknown

Check on to view all the vehicles in cluster mode. This groups up multiple vehicles that are located within small area and substitute the symbology of vehicles into clusters. Each cluster has a number inside to represent the total number of vehicles in that area. Uncheck it to view all the vehicles on map.

  • Cluster On

  • Cluster Off

Click on button to refresh the current status of all vehicles.

Click on button to pick column names that you want to show in the vehicle list table:

User can also sort table by clicking on besides each column. For example, if you want to sort the vehicle list table by Name, click on to sort vehicle names from A to Z or from Z to A.

When user clicks on a vehicle row, the detailed attribute information about this vehicle will show up in the information box below, and the map will zoom to the current location of the vehicle.

My Vehicle List

User can create/edit a vehicle category in “My Vehicle List” to better manage and view the vehicle list. This list is only viewable to the current user account itself. Each user can customize their own personal vehicle list, other accounts users cannot see.

Click on Vehicle Management button to open the Vehicle Management dialog window. The Vehicle Management is color-coded based on the department in order to differentiate them. All the vehicles are listed in the Vehicle Management.

Click on button to zoom into the current location of that vehicle.

Click on button to edit the Department, Username, Category or Driver information of that vehicle. The specific vehicle can be assigned to a user. Please note that this is intended for advance use only as it will overwrite the role-based vehicle assignment of the appointed user. The user will have access to only the vehicles assigned in this method.

Click on button to update the mileage and engine hours reading from the vehicle.

Vehicle History Search

MRF Web provides users the capability of searching historical vehicle data on the map.

Vehicle History Search function allows user to search historical data by date, time, and vehicle name. “Display As Line” will create temporary line segments of the vehicle’s path within the queried window.

Once the search result is shown on the map, user can click on “Playback” option to watch the animated vehicle travel throughout the time frame specified by the user (please refer to the following screenshots). The speed of the vehicle is also displayed in the Vehicle Tracking results window.

Vehicle Spatial Report

The Vehicle Spatial Report function allows user to search for historical vehicle data within an area of interest.

Traditional AVL systems usually only saves the vehicle location information as latitude and longitude values, but MRF Web treats tracking points as spatial data. Thus, advanced spatial operations are available.

The summary results will be returned on screen as a table (please refer to figure below). Click on button for any individual search result to zoom to the selected vehicle location for the specified time-period on the map.

Export Vehicle Data

Click on Export Vehicle Data button to export all the search results into a report in csv format. The report includes total distance traveled for each vehicle within the specified timeframe and total travel distance of all the vehicles.

Role-based Vehicle Assignment (For Website Admin Only)

Every user is assigned a role, and each role is assigned to a specific set of vehicles. The vehicle assignment can be done via the User and Role Management interface.

The Role Manager tap has the list of the roles within the organization. The vehicle assignment is under the Permission sub-menu.

Under the Permission sub-menu, the AVP tab has the list of the vehicles with AVL integration. All checked vehicles are accessible to the role. If any change is made, it needs to be updated before the change is applied.

Please note that the role-based vehicle assignment will be overwritten if a vehicle is assigned to a user as stated in the section 3.3 Vehicle Management.
