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.
1.5 – 1.75
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.
This project will improve intersection design and operation, facilitating more efficient traffic flow and reducing congestion caused by intersection-related crashes. This project includes adding left turn lanes, which remove turning vehicles from the flow of traffic and reduce slowdowns and congestion. The addition of left turn lanes also has the potential to reduce rear end crashes as well as a variety of other left turn conflicts, further reducing congestion caused by resulting crashes.
No
Yes
FM 518 connects directly to IH 45 and SH 146, both of which are identified as evacuation routes.
Other Investment Category Focused Criteria
No
The project is not located on a Critical Urban Freight Corridor. The project is located on the TxDOT Freight Network. The project improves regional goods movement by intersection improvements which will facilitate more efficient traffic flow and reducing congestion caused by intersection-related crashes.
The project is not located in a high growth area. The population is projected to grow by 16.0% and jobs are projected to increase by 16.5%. One Single-Family housing land use changes announced or modeled off Davis Rd.
ADA Ramps are required to be installed at intersections if dimensions allow for it safely.
No existing or planned transit service is provided on this facility.
This project will improve intersection design and operation, reducing intersection-related crashes. The reduction in crashes will reduce periods of inoperability due to vehicle collisions.
This segment contains pavement in Poor 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
0
13.53
Crash rates for this segment are per 100 million VMT. The fatality rate is 0, lower than the statewide average (1.23), and the serious injury rate is 13.53, higher than the statewide average, (6.18). In response to safety concerns, this project aims to enhance intersection design and operation, thereby reducing intersection-related crashes. Additionally, ADA ramps are required and will be installed at intersections where dimensions permit safe implementation, promoting accessibility and safety for all pedestrians. The consolidated crash reduction factor for this project is 155% as a result installing raised Medians (WC 203), and providing additional left turn lane (WC 519), lengthen left turn lane (WC 520), adding right turn lane (WC 521), and lengthening right turn lane (WC 522).

The area surrounding the project segment has a higher low-income population (16.38%) as compared to the regional average of 13.5%. The area surrounding the project segment has a lower minority population (38.59%) 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 flooding, high vulnerability to storm surges, and is ranked as moderate-high criticality for accessing key facilities.
The area surrounding the project segment has a higher low-income population (16.38%) as compared to the regional average of 13.5%. The area surrounding the project segment has a lower minority population (38.59%) as compared to the regional average of 65% minority. 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 (Categorical Exclusion, Environmental Assessment, or Environmental Impact Statement) will be conducted to identify, avoid or mitigate potential impacts to the natural or human environment.
