Regional Transportation Plan Goals
According to the H-GAC 2045 RTP, this project type falls under the Expand strategy. Because it will provide additional capacity to the roadway and reduce primary and secondary crashes caused by congestion. Projects falling under the Expand strategy directly support two of H-GAC’s goals: moving people and goods efficiently and strengthening regional economic competitiveness. Expand projects also indirectly advance H-GAC’s goals of improving safety, achieving a state of good repair, and protecting cultural and natural resources. [1] Improve Safety: This project will provide additional capacity to the roadway and reduce primary and secondary crashes caused by congestion. Improved active transportation infrastructure will allow pedestrians to safely use the facility and reduce points of conflicts with vehicles, thus improving the overall safety of the segment. [2] Achieve & Maintain State of Good Repair: In a widening/reconstruction project, old pavement is removed and new pavement is constructed, thus increasing the state of good repair. This project will allow alternative modes of transportation to vehicle traffic, reducing wear and tear on nearby facilities. [3] Move People and Goods Reliably and Efficiently: This project will reduce congestion and reduce resulting crashes, increasing the reliability of the facility. [4] Strengthen Regional Economic Competitiveness: This project will reduce congestion and resulting crashes by adding capacity and allowing alternatives to vehicle traffic. This will increase the truck travel time reliability of the facility, boosting regional and economic competitiveness. [5] Conserve and Protect Natural and Cultural Resources: This project will include improved drainage, which will benefit the natural resources abutting the facility. This project will reduce emissions caused by idling and congestion.

Potential Crash Reductions

Crash rates for this segment are per 100 million VMT. The fatality rate is 0, lower than the regional average (1.23), and the serious injury rate is 15.862, higher than the regional average (6.18). The widening of the roadway will provide additional capacity to the roadway and reduce primary and secondary crashes caused by congestion. The addition of bicycle infrastructure and pedestrian infrastructure will allow cyclists and pedestrians to safely use the facility and reduce points of conflict with vehicles, thus improving the overall safety of the segment. The inclusion of medians reduces the quantity and severity of crashes at intersections and provides refuge to crossing pedestrians. As an access management strategy in corridors, medians reduce mid-block left turn-related crashes. They enhance traffic flow and can be used as part of a traffic calming strategy to reduce speed. The consolidated crash reduction factor for this project is 185%, as a result of converting from a 2-lane to 4-lane divided facility (WC 538), adding medians (WC 201), and providing pedestrian and bicycle infrastructure (WC 407).
Potential Congestion Reductions
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 1.06, indicating that it takes 1.06 times as long to travel this corridor in the peak period than average, which is mildly congested.
This project will widen from 2-lane to 4-lanes (WC 517) to address future congestion and implement access management treatments including a raised median (WC 203), realignment of curve (safety and traffic flow improvements), and bike/ped facilities (multimodal opportunities - WC 407). The segment will be brought up to TxDOT and FHWA safety design standards.
Connectivity to Jobs, Medical Facilities, and Activity Centers
Yes

No
Yes
Project improves mobility and connects to Downtown Hempstead (activity center). There is a Texas Health and Human Services Commission office nearby this project limit (Mack Washington Ln) as well as a Dialysis Center (DaVita) near the Cottonwood/FM 1488 intersection.
State of Good Repair
Less than 30 years
Good
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.
Biking and Walking Conditions
10 ft Shared Use Paths and 5 ft sidewalks are being constructed on both sides of the entire length of this project. Shared use paths provide a low-stress experience for active transportation users, increasing user safety and health while improving regional connectivity. The addition of sidewalks will create transportation alternatives and allow pedestrians greater access to services and improve quality of life.

The area surrounding the project segment has a higher low-income population (22.02%) as compared to the regional average of 13.5%. The area surrounding the project segment has a lower minority population (63.1%) 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.
The area surrounding the project segment has a higher low-income population (22.02%) as compared to the regional average of 13.5%. The area surrounding the project segment has a lower minority population (63.1%) 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.
Hurricane Evacuation Route
No
Yes
FM 1488 connects directly to US 290 which is an evacuation route.
