# Data Driven PHB Ranking

Created for Arterial Management - Austin Transportation Department

## Criteria Point Breakdown :100: 

The Criteria Ranking Score is based on the Total Rank Score of 100 points, which is broken down into 3 Sections: Demand, Risk, and Safety. Each Section has a set number of Categories with specific point breakdowns, depending on the data being measured. The list below breaks down the Categories by Section, providing details on point structure.

## Demand (35 pts)

### 12 Points Max. Combined :shopping\_cart: :school: :church: :park: :office: :homes: :canned\_food: 

* **TOTAL\_12MAX (12 points)**
  * Large Retail - LARGE\_RETAIL = 3 points **per** large retail space
  * School - SCHOOL = 3 points **per** school
  * Church - CHURCH = 3 points **per** church
  * Park - PARK = 3 points **per** park
  * Large Office - LARGE\_OFFICE = 3 points **per** large office space
  * Multi-Family Housing - MULTIFAMILY = 3  points for apartment complex or condos

* **PUBLIC\_TRANS (5 points)**
  * Multiple bus routes = 5 points
  * Single bus route = 3 points
  * Not along a bus route = 0 points

### Household Income :moneybag: 

* **HH\_INCOME (10 points) - based on U.S. Census Block Group data**
  * Median income is 40% - 100% below median income of the city = 10 points
  * Median income is 25% - 40% below median income of the city = 6 points
  * Median income is 0% - 25% below median income of the city = 3 points
  * Median income is greater than median income of the city = 0 points

### Population Density :homes: 

* **POP\_DENSITY ( 5 points) - based on U.S. Census Block Group data**
  * Greater than 100% above median population density = 5 points
  * 75% - 100% above median population density = 4 points
  * 50% - 75% above median population density = 3 points
  * 25% - 50% above median population density = 2 points
  * 0% - 25% above median population density = 1 points
  * Less than median population density = 0 points

### Customer Service Requests :sos: 

* **CSR (3 points)**
  * CSR = 3 points
  * No CSR = 0 points

## Risk (40 pts)

### Number of Travel Lanes :motorway: 

* **TRAVEL\_LANES (8 points)**
  * Greater than or equal to 6 lanes = 8 points
  * 4 - 5 lanes = 5 points

  * Greater than 840' - 1,020' = 8 points
  * Greater than 660' - 840' = 6 points
  * Greater than 480' - 660' = 4 points
  * Greater than 300' - 480' = 2 points
