Sidewalk Walkablity, MAPC Region
|
The Sidewalk Walkability layer was created using the Executive Office of Transportation roads layer and giving roads that had a left sidewalk a weight of one and roads with a right sidewalk a weight of one. The weights were then added together to result in a weighted sum of 0, 1 or 2, representing the respective number of sidewalks and color coded. Using the inquiry tool the user can find out more details about the sidewalk features (i.e. side of the street, width). |

Traffic Analysis Zone (TAZ) Model Area, CTPS Region, 2005
|
A transportation analysis zone (TAZ) is the unit of geography most commonly used in conventional transportation planning models. TAZ’s are a used to assign information on population, employment, and households to a specific location. TAZ’s are the places where trips begin (trip producers) or end (trip attractors) and the centroids of the TAZ are connected to the transportation system via centroid connectors (a proxy for local roads). This allows the person trips that were derived from the TAZ’s level data to travel to other TAZ’s. The size of a TAZ varies in models, ranging from very large TAZ’s in the suburbs to small ones in the downtown. A large number of zones will increase forecast accuracy but will require more data and computer processing time. This data layer contains the 2727 TAZ’s covering all of Eastern Massachusetts. |

Top 200 Vehicle Crash Intersections, 2003-2005, State
|
Through crash data obtained by state and local officals, the Massachusetts Highway Department compiled this datalayer displaying the top 200 highest rated intersections for crash location. This data was gathered to help provide a foundation for the implementation of safety improvement projects in these areas. The rating system weighted each site using a variety of factors. Please note that this data should be used as a generalized viewing tool rather than a listing of the highest crash prone areas. |
