Navigation
Paging Buttons Navigate along the selected route by toggling between the different pages in the Route Log. Each number represents a different route log page, or section of route. Press the '<<' button to navigate to the first page. Press the '<' button to navigate to the previous page. Press the '>' button to navigate to the next page. Press the '>>' button to navigate to the last page. The first and last pages along the route are defined in the Route Selection Page. TopTOP

Overview Map
Overview Map The Overview Map is a map of the section of route defined in each route log page. The ruler mileposts will align to where the route enters and exits the map. It is possible that the ruler may not align with the route in the Overview Map in between where the route enters and exits the map due to the curvature of the route. TopTOP

Straight Line Diagram
Straight Line Diagram The Straight Line Diagram provides a visual depiction of intersecting elements such as roads, rivers, and town boundaries along the route. Only one direction (northbound, southbound, eastbound or westbound) of a route will be shown at a time. The gray rectangle in the middle shows depicts the route. Mileposts are shown on the route where an intersecting element crosses the route. Hover over an element to display the milepost and name of the intersecting element at the bottom of the Straight Line Diagram. TopTOP

Straight Line Diagram Legend
Straight Line Diagram Legend The Straight Line Diagram Legend shows all the elements that could appear in the Straight Line Diagram. TopTOP

Ruler
Ruler The Ruler displays the points along the route within a route log page at .10 mile increments. The points should align with the Straight Line Diagram and the Route Attribute View. With the exception of the two points on the ends, the points may not align with the Overview Map because it does not take into account the curvature of the road. TopTOP

Route Attribute View
Route Event Attribute Table The Route Attribute View shows route attributes as they occur along the route. The route attribute information comes directly from MassDOT's Route Inventory file. Most attributes within the Route Attribute View are coded. To locate a particular code, click on the item name on the far right and a dialog will appear. The data definitions for the attributes are also located in the Road Inventory Data Definitions document. TopTOP

Important Information

Each numbered roadway is measured in mileposts from beginning to end, with milepost signs in the field that correspond to milepoints shown in the 2.0 mile roadway sections in MRLA. To better coordinate between the milepost in the field and the road inventory, a linear referencing system (LRS) has been developed within the road inventory database. The LRS provides the ability to connect the milepost signs in the field with the road inventory file through the use of milepoints. MRLA uses the LRS to display the attributes of the road inventory numbered routes in orthographic, graphic and tabular format. The data displayed in this application may not be what the user intuitively expects to see. The below information describe cases where and when the data displayed may not match expectations.

Primary versus opposing route directions
Primary routes are routes that run from West to East or South to North. Opposing routes are the same as primary routes, but in the opposite or opposing direction. Opposing routes run from East to West or North to South. For example: I 95 NB is a primary route, while I 95 SB is an opposing route. Primary and opposing routes are viewed by automobile drivers as the same indistinguishable route, but the LRS stores each direction as a separate route so that unique events that occur on either side of the route can be identified, managed and reported. MRLA displays roadway attribute information starting at a zero milepost located at the southern or western most point of all primary and opposing routes, this way the milepost on the primary and opposing side of a route match. When the primary and opposing directions are not parallel for a short distance, the milepoints continue to increase separately. Once the routes rejoin, an equation or adjustment occurs to re-align the milepoints to match the measure of the longest route at that point.

SLD displays route in once direction
Straight Line Diagram (SLD) displays route in one direction only. Though the highway may appear as if it is bi-directional, the SLD will is only showing the route in one direction (i.e. northbound, southbound, eastbound or westbound).

Straight Line Diagram (SLD) display of intersections differs for divided and undivided routes
Divided routes (such as interstates) have medians between opposing lanes of traffic. Undivided routes principally function without barriers or gaps between opposing lanes of traffic, but often have short divided sections near large interchanges. For divided routes or sections of separated undivided routes, each direction of traffic is recorded as an individual route. Only roadways intersecting the chosen individual route are displayed in the SLD. Roadways intersecting the opposing lanes of traffic are not displayed. For example, if an undivided northbound route is selected, the SLD will display all intersecting roadways on the northbound and southbound direction. However, for the short divided sections along the route, the SLD will only display roadways that intersect with the northbound side of the route. For divided routes or separated sections of undivided routes, the SLD will display intersections that carry across both directions regardless of which direction was chosen.

The Straight Line Diagram takes the curvature out of the routes
The graphic representation of intersecting features is most accurately displayed in graphic format when the curvature of each route is removed. As a result, intersecting features such as streams, bridges and roadways may not line up accurately to the features in the orthophoto image or data view, especially after sharp turns.

Negative mileposts and mileposts exceeding route length
The start and/or end symbol shown in the Route Selection Map will not display if negative measures or measures larger than the maximum measure for a selected route are entered in the Mile post “From” and “To” option. However, the route will still be highlighted.

Equation Routes
The data displayed is based off the mileposts in a calibrated milepost route GIS dataset known as the equation routes. This means that rather than having equation points along the route at certain locations in order to adjust the measurement values, the route is instead calibrated to seamlessly adjust and integrate the measurements along the route. The cause for adjustment is mainly to align the milepost measurement values along both directions of the route.
