A traffic analysis was conducted for the project corridor. Traffic analysis for the 2023 no-build scenario shows that the calculated vehicular level of service (VLOS) of turning movements and the 95th percentile queue length (maximum of lane groups of each approach) shows in good range in the major flow direction (N-S traffic flow along N Houston Rosslyn Road). However, the delays are acceptable, and the queue lengths can get long. On the minor flow direction (Alabonson Road), the VLOS becomes E at its worst and the queue length is considerable. For intersections, the impact of the project is measured by delay, which is also adopted by the Highway Capacity Manual (HCM) and is the basis for the vehicular LOS. The delay is transformed into corridor delay as follows to calculate the Travel Time Index (TTI). Then the corridor travel time in peak period is divided by the same measure in free-flow period to obtain the TTI. The corridor is assumed to be between the two neighboring signalized intersections, Woodsman Trail on the north and W Bank Gulf Road on the south. The length of the segment is 2883.5 ft and the speed limit is 40 mph. Hence, hypothetically, the travel time (free-flow time) of the segment with the posted speed limit is 49 seconds. In urban areas, the delay is mainly caused by the intersections rather than the roads themselves. So, the fluctuations in the travel time are mainly caused by the intersection delay changes. Since the signal is semi actuated, it is assumed that in free-flow periods, the major flow vehicles are not delayed at the signal and so their travel time is equal to 49 seconds. For the peak period, the delay is assumed as 49 seconds plus the intersection approach delay. Dividing the peak travel times by the free-flow travel times results in the TTI.

For intersections, the impact of the project is measured by delay, which is also adopted by the Highway Capacity Manual (HCM) and is the basis for the vehicular LOS. The delays of southbound and northbound approaches for N Houston Rosslyn Road for 2028 is considered and in the build scenario, to improve the traffic operation of the intersection, a right turn storage lane is added westbound on Alabonson Road. The delay is transformed into corridor delay as follows to calculate the Travel Time Index (TTI). Then the corridor travel time in peak period is divided by the same measure in free-flow period to obtain the TTI. The corridor is assumed to be between the two neighboring signalized intersections, Woodsman Trail on the north and W Bank Gulf Rd on the south.

The project will alleviate congestion in several ways, particularly through intersection improvements. Intersection improvements will include modified signal phasing, addition of dedicated turn lanes at the intersection of North Houston Rosslyn Road, access management through median reconfiguration at the intersection of W Little York Road/Victory Drive to add a dedicated turn lane to optimize traffic flow and to provide safe crossings for bicyclists and pedestrians. As residents currently cross the railroad to access Alabonson Park, the project will upgrade the at-grade railway crossing and install new, safe sidewalks and SUP crossings. The multimodal corridor will encourage users to consider alternative modes to vehicles. The contiguous sidewalk and shared use path will further improve access to transit and offer reliable travel times along the corridor.

Alabonson Road is not designated as a freight corridor and has a truck traffic of 3.5% along the corridor. Truck volume is higher in adjacent corridors, including West Little York, Antoine Drive, and North Houston Rosslyn Road, and it is 6.5%, 6.8%, and 5.1%, respectively. To relieve truck traffic on these adjacent routes, Alabonson Road can be used as an alternative. Signal phasing at North Houston Rosslyn Road and at the intersection of West Little York Road coupled with lane reconfiguration will keep the traffic flowing through the area. By expanding access to METRO Route 3, the multimodal corridor will encourage users to consider alternative modes to vehicles. Reconstruction of this corridor will encourage multimodal usage, reduce conflicts, improve traffic operations, travel times and connectivity for the region, reduce bottlenecks, and enhance the safety of all road users. The industrial land uses and commercial establishments in the area will benefit directly from the improvements. Through landscaping improvements and optimized traffic operations, the project will further mitigate any truck-related impacts on these communities, including noise, safety, and emissions.
The Alabonson Road project provides access to several important activity centers and will provide improved access to a variety of institutional, residential and commercial land uses. The project corridor provides access to Ermel Elementary School, As We Grow Learning Center, Hoffman Middle School, Smith Elementary School, Alabonson Park, White Oak Bayou Trail, and multiple retail and industrial businesses along and within a quarter-mile distance. The project will also provide access to Harmony School of Endeavor within a half-mile radius. The project will reconstruct the failing pavement and create a well-lit, seamless, safe, and accessible pedestrian/bicyclists’ path for the residents, connecting the new Alabonson Park, recreational facilities, commercial areas, METRO bus routes, and local schools. Per the H-GAC Regional Land Use Information System, an adjacent ~11 acre property (Parcel ID: 1352840010001) has been built for a distribution warehouse. The warehouse includes 153,188 square feet of distribution facility with 48 docking stations. Utilizing H-GAC's Activity-Connectivity Explorer (ACE) Tool, an analysis of the population and job growth for TAZs 4697, 989, 1041, 949, 977,991 and 1040 (all within ¼ mile of Alabonson Road and W Little York Rd), the area will see an increase of 3,643 residents and 436 jobs between 2018 and 2045. This translates to a population growth of 38.9% and jobs increase of 28.6% between 2018 and 2045.
The project corridor has a high need for improved walking and biking infrastructure. Currently, there is only a short section of narrow sidewalk in poor condition and there are no bicycle facilities, resulting in unsafe conditions for pedestrians attempting to access parks, commercial establishments, etc. by non-automobile modes. The proposed project is a total reconstruction of Alabonson Road from W Little York Road/Victory Drive to N Houston Rosslyn Road and widening of sidewalks on W Little York Road between Gum Grove Lane and BNSF railroad on W Little York Road along with intersection improvements including median reconfigurations to optimize traffic flow and enhance pedestrian safety. The Project will replace and upgrade Alabonson Road with multimodal transportation options within existing public right-of-way. The COH bike plan recommends Alabonson Road to have an on-street high comfort bike lane. However, due to right-of-way (ROW) constraints, the proposed cross section includes an 8-ft wide shared use path on the west & south side and 6-ft wide dedicated sidewalks on east & north side of Alabonson Road with 4-ft wide safety buffer from travel lanes. Sidewalks along W Little York Road are in a poor state of repair and are inconsistent with the current COH IDM standards. These sidewalks will be replaced with 6-ft wide sidewalks, American Disability Act (ADA) compliant ramps, median refuges at intersections, and will include a 4-ft wide safety buffer from travel lanes. These proposed improvements will provide a safe, contiguous, accessible, dedicated multimodal realm. Improvements along the project corridor will provide a direct, safe connection to the Alabonson Park and to the White Oak Bayou Greenway Trail, which is a dedicated, off-street, 10-foot-wide concrete trail connecting residents to nearby parks, community resources and transit. This trail also includes a hike-and-bike bridge over White Oak Bayou parallel to Alabonson Road. The project will eliminate barriers for pedestrians and bicyclists crossing the BNSF railroad on Alabonson Road near the intersection of N Houston Rosslyn Road that separates Alabonson Park from nearby residential neighborhoods. Sidewalk improvements along W Little York will provide seamless access to Hoffman Middle School, YES Prep Hoffman and Smith Elementary School and METRO Route 3 on W Little York Road/Victory Drive. Improvements along this corridor will create a contiguous, cohesive corridor making smooth, multimodal connections for residents and visitors for increased access to the economic and social destinations in and around the area.
The project's south terminus connects to METRO Route 3 (Langley-Little York) transit stop that is located on Victory Drive, 350-ft east of the intersection of Alabonson Road and W Little York Road/Victory Drive. Antoine Drive, which is located a quarter-mile distance the intersection of Alabonson Road & W Little York Rd/Victory Drive is served by METRO Route 85. These two routes connect residential, employment, and commercial centers in the Spring Branch East, Washington Avenue Coalition/Memorial Park, Heights, Acres Homes, Northside, Houston Gardens, and Downtown areas. Intersection improvements including median and lane reconfiguration with traffic signal phasing at W Little York/Victory Drive will improve operational efficiency by decreasing travel time delays for buses. METRO Route 3, which loops around at Hollister to the west, will provide improved access to employment and retail. Overall, the enhancements at W Little York Road intersection will result in better transit time reliability.
The project is a total reconstruction of Alabonson Road from W Little York Road/Victory Drive to N Houston Rosslyn Road. The project will replace and upgrade roadway, multimodal and public utility infrastructure within the existing public right-of-way. Alabonson Road currently has two narrow travel lanes, deep ditches, and no sidewalks for the majority of the corridor's length. The corridor includes a bridge and a railroad crossing with no pedestrian facility. The pavement condition and striping along the corridor is in poor condition. Insufficient street lighting, crosswalks, lack of a pedestrian facility, and lack of accessible ramps forces pedestrians to share the street with vehicles, including heavy trucks, thereby endangering pedestrians and causing delays and congestion in the event of a collision. The reconstructed Alabonson Road will have improved pavement condition, safer conditions, and more efficient traffic flow, thereby reducing the potential for crash incidence, particularly at the intersection of W Little York Road and N Houston Rosslyn Road. The addition of an off-street bike and pedestrian facility along the corridor will increase overall road user safety, systemic travel-time reliability, and lower the risk of infrastructure damage as a result of intermodal crashes. Furthermore, it can act as a north-south relief route between W Little York Road and N Houston Rosslyn Road for people traveling in the area. Additionally, the project will design curb and gutters to control the flow of water by directing it towards designated drainage areas. This will prevent water from pooling on streets and sidewalks, reducing the risk of accidents and infrastructure damage. Alabonson Road connects various major thoroughfares and provides parallel connectivity to roads such as Antoine Drive. When reconstructed, the roadway can provide an alternate connection for those traveling in the area and will be able to function as a more effective relief route in the event of an emergency event, major traffic disruption or evacuation scenario on any of those roadways.
Alabonson Road's pavement is failing and nearing the end of its useful life. Its PCI index ranges from primarily poor to fair, with a small portion in satisfactory condition. The corridor falls under the jurisdiction of both the City of Houston and Harris County. For the majority of the project limits, the existing asphalt pavement is in poor condition, unsafe, and uncomfortable due to major transverse and longitudinal cracks and faded striping. The existing sidewalks on the west side of the roadway from West Little York to Vinewood Drive/White Oak Bayou Trail Entrance along west of the roadway are not ADA compliant or in compliance with the City's IDM standards. The sidewalk is unsafe and inaccessible for everyone because they are deteriorated, narrow, and present a tripping hazard. There are currently no pedestrian or bicycle facilities along the remaining corridor segment. A section of roadway that is within the city limits and county limits was overlayed in early 2022 and has been restriped based on aerial imagery. Since the facility is over 40 years old and has reached the end of its useful life, the corridor in general is in poor condition. The reconstruction of the corridor will replace the failing asphalt pavement with concrete pavement to reduce long-term maintenance costs in the future. The reconstruction will also upgrade existing multimodal and public utility infrastructure and enhance by installing additional facilities within the existing public right-of-way. The reconstruction will transform the corridor, improving structural and function performance, rideability, and reliability, as well as increasing community connectivity and residents' access to resources. These upgrades will reduce events of accidents, injuries, and fatalities, and associated costs. Additionally, the updated stormwater drainage facilities proposed include removing the existing open ditches to replace with a curb and gutter cross section with subterranean drainage, which will mitigate long term maintenance costs associated with mowing, debris removal, and retrenching. The existing facility is in a state of continuous maintenance and rehabilitation, the overall reconstruction will result in cost savings and improve the state of good repair for all users.

Over the 5-year period between 2018 and 2022, a total of 205 crashes occurred along the project corridor, including two fatal crashes and two serious injury crashes. One of the fatal crashes was a pedestrian crash that occurred in 2019. The other fatal crash that occurred in 2022 was caused by failing to drive in a single lane. Both of the serious injury crashes occurred in 2020 due to failing to control speed and failing to drive in a single lane separately. To address the safety concerns of this roadway, a set of improvements has been proposed: Alabonson from West Little York Rd (WLY) / Victory Dr to N Houston Rosslyn Rd: • Reconstruct Alabonson Road from WLY / Victory Dr to N Houston Rosslyn Rd with new concrete pavement and curb and gutter • Install a new sidewalk and a shared use path (SUP) along Alabonson Road from WLY / Victory Dr to N Houston Rosslyn Rd • Upgrade traffic signal from span wire to mast arm at the intersection of Alabonson Rd and N Houston Rosslyn Rd • Install a new WB right turn lane at the intersection of Alabonson and N Houston Rosslyn • Improve or install crosswalks, pavement markings, and ADA ramps as needed along the entire corridor WLY / Victory Dr & Alabonson Rd Intersection: • On the West Little York Road Eastbound approach, the shared lane (right turn and through) is converted to a through-only lane. Therefore, the right turn bypass lane will have a dedicated lane. • Add one through lane on the WLY northbound approach (with space taken from the existing raised median) • Improve signal timing at the intersection of WLY/Victory Dr &Alabonson Rd • Widen sidewalk on both sides of streets from the railroad track to Gum Grove Ln along WLY Rd, and from the intersection to Tall Pine Rd along Victory Dr • Improve crosswalks and pavement markings along the corridor The proposed improvements correspond to various work codes, each with its own associated crash reduction rate: Alabonson from N Houston Rosslyn to Gum Grove Lane 305, 407 Safety Lighting at Intersection, Install Sidewalks 53% 303, 401 Resurfacing, Install Pavement Markings 50% 304, 407 Safety Lighting, Install Sidewalks 46% 108, 521 Improve Traffic Signals, Add Right Turn Lane 34% Alabonson from N Houston Rosslyn to Vinewood Drive 403, 407 Install Pedestrian Crosswalk, Install Sidewalks 74% Intersection of Alabonson and N Houston Rosslyn 108, 305 Improve Traffic Signals, Safety Lighting at Intersection 33% 108, 401, 403 Improve Traffic Signals, Install Pavement Markings, Install Pedestrian Crosswalk 30% WLY / Victory/Alabonson Intersection 110, 403 Install Pedestrian Signal, Install Pedestrian Crosswalk 36% 108, 401, 403 Improve Traffic Signals, Install Pavement Markings, Install Pedestrian Crosswalk 30% 517 Add Through Lane 28%

Currently, Alabonson Road is drained entirely by open ditches on both sides of the roadway. There are two major outfalls at White Oak Bayou (E100-00-00) and at an upstream tributary of White Oak Bayou (E140-00-00). These open ditches have been poorly maintained and are often overgrown with weeds and collect trash. The proposed improvements include installation of a curb and gutter cross section which will improve stormwater drainage conditions within and around the project corridor. These stormwater drainage improvements will include curb inlets, grate inlets, and reinforced concrete pipes. This combination drainage infrastructure will ensure the roadway will have the necessary drainage capacity to exceed local design requirements and provide improved drainage over the existing conditions. By placing the stormwater drainage facilities underground, it will be possible to introduce the bicycle and pedestrian facilities on the corridor. Additionally, the underground drainage facilities will reduce costly maintenance expenses including mowing, trash/debris collection, and periodic retrenching associated with open ditches. Inwood Forest Stormwater Detention Basin, in the vicinity of Alabonson Road encompasses a total of 12 interconnected stormwater detention basins. The stormwater detention basins are being built by the Harris County Flood Control District (HCFCD) on the former golf course property to provide flood damage reduction benefits during heavy storms and to mitigate impacts of future public City of Houston drainage projects as appropriate. A part of the proposed project corridor falls within the Inwood Forest drainage basin and will benefit from the detention basin project.

At least 4.5 out of 10 households living on either side of Alabonson Road are defined as low to moderate income households by HUD. The American Community Survey (ACS) for 2022 reports that 18% of the households in the corridor do not own a car. Children make up 29.6% of the population along the corridor, and 15.7% of the population is disabled. The residents surrounding the project area are in great need of safer bicycle and pedestrian facilities, which do not currently exist on this corridor. On the corridor, the project will build either a 6-ft wide sidewalk or an 8-ft wide shared use path with a 4-ft wide safety buffer between it and the travel lane. The bike and pedestrian facility will facilitate easier access to transit stops located on Victory Drive and Antoine Drive, parks and trails, commercial establishments, and schools in the area. Additionally, the number of streetlights along the corridor will be greatly increased, resulting in a much safer and accessible conditions for drivers, pedestrians, and cyclists throughout the day and night. Other safety enhancements will be included in the project at the intersections such as high visibility crosswalks, pedestrian/bicycle phase signaling, and pedestrian median refuges as needed.

Impacts on Natural and Cultural Resources
The southern portion of the project is within the 100- or 500-year flood plain associated with White Oak Bayou. The area is largely developed with residential uses. The project is primarily reconstruction of an existing roadway within the same footprint; the addition of a shared-use path is not anticipated to adversely impact flooding. Coordination will be done with the appropriate flood control agencies as needed. The proposed project crosses White Oak Bayou and an associated drainage ditch south of Greenway Forest Lane and is adjacent to several other designated wetlands; the bayou crossing is on an elevated bridge and the ditch crossing is at grade. Project work is not anticipated to fill or dredge any wetlands and adverse impacts are not expected. There are no designated historic resources within ¼ mile of the proposed project. The entirety of the project alignment is in an area designated as “No Survey Recommended” for archeological resources. The northern end of the alignment is adjacent to an area designated as “Surface Survey Recommended, No Deep Reconnaissance Recommended.” This area has limited development, therefore increasing the potential for archeological resources to be present. If project work extends into this adjacent area, a surface archeological survey may be required.
Over a 20-year planning horizon from 2026-2045, the project will reduce 0.46 metric tons of NOx and 0.58 metric tons of VOCs.
