Investment Category-Focused Criteria

No

1.0 – 1.25

Travel Time Index (TTI) is a ratio that compares peak period travel times along a corridor to average travel times, thus estimating a relative level of rush hour congestion. Current TTI for the project area is 1.14, indicating that it takes 1.14 times as long to travel this corridor in the peak period than average, which is mildly congested.

1.0 – 1.25

Travel Time Index (TTI) is a ratio that compares peak period travel times along a corridor to average travel times, thus estimating a relative level of rush hour congestion. Current TTI for the project area is 1.14, indicating that it takes 1.14 times as long to travel this corridor in the peak period than average, which is mildly congested.

The project includes the following Congestion Management Strategy: Added Capacity and Access Management. Adding capacity will relieve congestion on the facility by allowing for a reduced vehicle to capacity ratio. Further, it will allow more room for traffic to avoid crashes on the segment, reducing congestion caused by crashes. As an access management strategy in corridors, medians reduce mid-block left turn related crashes. They enhance traffic flow and reduce the quantity and severity of crashes at intersections and resulting congestion.

Other Investment Category Focused Criteria

Yes

The project is located in a high growth area. The population is projected to grow by 16.0% and jobs are projected to increase by 16.5%. Some residential land use changes announced or modeled.

Bike/Ped facilities will be constructed on this route. The addition of sidewalks will create transportation alternatives and allow pedestrians greater access to services and improve quality of life. Bike lanes increase the safety of riders and improve regional connectivity.

No existing or planned transit service is provided on this facility.

The project will reconstruct and widen lanes to allow more space to move disabled vehicles and to better maintain flow on the facility after vehicle collisions.

The pavement on this facility is mostly in Good condition, according to TxDOT and FHWA guidelines. In a widening/reconstruction project like this project, pavement is removed and new pavement is constructed, thus increasing the state of good repair and extending the service life of the facility.

Planning Factors Criteria

3.56

3.56

The Crash rates for this segment are per 100 million vehicle miles traveled. The fatality rate is 3.56, higher than the regional average (1.23), and the serious injury rate is 3.56, lower than the regional average (6.18). The reconstruction and widening of the roadway will provide additional capacity to the roadway and reduce primary and secondary crashes caused by congestion. The addition of the bicycle and pedestrian infrastructure will allow cyclists and pedestrians to use the facility and reduce points of conflicts with vehicles, thus improving the overall safety of the segment. The consolidation crash reduction factor for this project is 118% as a result of providing additional travel lanes (WC 517), installing pedestrian and bicycle infrastructure (WC 407) and adding raised medians (WC 203).

The area surrounding the project segment has a lower low-income population (6.86%) as compared to the regional average of 13.5%. The area surrounding the project segment has a lower minority population (45.09%) as compared to the regional average of 65% minority. Because of its central location in the regional network, the project will produce improvements in mobility and connectivity for vulnerable populations as well as connectivity to schools, medical facilities, and social services for the regional population. As a result of the improvement, vulnerable populations will have increased resilience and evacuation capacity in the event of hazards. According to HGAC’s Regional Resilience Tool, the project segment sits on a facility that is rated as having moderate vulnerability to storm surge and flooding. FM 270 runs parallel to IH 45 which is an evacuation route. The project will improve drainage to ATLAS-14 standards, which reduce flooding events and their impact on vulnerable populations.

TxDOT’s Environmental Process is designed to ensure compliance with Title VI of the Civil Rights Act of 1964, and the Executive Order on Environmental Justice. Standard practice is to implement projects that provide user safety and operational efficiency while taking into account environmental quality and impacts to surrounding communities. In practice this means identifying and assessing potential project impacts, then proposing measures to avoid, minimize and/or mitigate disproportionately high and adverse effects to Environmental Justice Populations. For example, the project will improve drainage to ATLAS-14 standards, which will mitigate impacts from added capacity to vulnerable populations.

Impacts on Natural and Cultural Resources

This project is in conceptual development. If required, the appropriate Environmental Document, an Environmental Assessment, will be conducted to identify, avoid and mitigate potential impacts to the natural or human environment.
