In Texas, high-occupancy vehicle (HOV) lanes are an integral part of urban mobility. Although an extensive system of permanent HOV lanes is planned for the Dallas–Fort Worth area, the Texas Department of Transportation and Dallas Area Rapid Transit have implemented interim HOV lanes by retrofitting them into existing freeways. Safety is examined fo...

Implementing minor geometric and operational improvements on existing freeways to remove bottlenecks has the potential of achieving high benefits, yet it is not routinely done. Four case studies of bottleneck removal projects in Texas are presented in some detail with before-and-after evaluations of speeds, volumes, and crash histories. The case is...

The objective of a two-year study was to recommend school site planning guidelines for transportation-related elements such as site selection, general site requirements and design, bus operations, parent drop-off and pickup zones, driveways, turn lanes, signing and marking, parking, and pedestrian and bicycle access. The research team based these g...

... Hence, implementation of managed lanes can efficiently optimize the available freeway capacity. In order to understand the operational interaction between managed and general purpose lanes, Cooner and Ranft [4] carried out a safety evaluation for concurrent flow of buffer-separated interim HOV lanes, retrofitted into two existing freeways in Dallas. They observed an increase in crash rate between the HOV lane and the first adjacent general purpose lane. ...
... Restriping refers to minor lane reconfigurations such as addition of auxiliary lanes and shoulders, ramp reconfigurations, and intersection reconfigurations. For example (76), a bottleneck area on IH 35 East in Dallas was improved by replacing a little-used exit ramp with an entrance ramp, which resulted in considerable reduction of delay and crash rate. Another bottleneck area on northbound SH 360 in Arlington was improved by extending an auxiliary lane between two exiting exits by 700 ft to the next exit, which cost $150,000 yet resulted in estimated yearly delay benefits of $200,000 and substantial reduction of injury crashes. ...
... The Cristiano Machado Busway, in Belo Horizonte (Brazil) remains the street with the highest crash frequencies citywide, despite the presence of a central Busway. In Delhi, after the implementation of the BRTS system, traffic fatalities initially increased on the corridor, and crashes between buses and pedestrians a more positive impact than others ( [12], [14]) ...
... This leads to an unevenly distributed traffic density, resulting in a higher density near the exit and additional delays for through traffic. Walters, Cooner, and Ranft (2005) analyzed the impacts of another alternative method of dropping the auxiliary lane, extending the auxiliary lane to the second exit. Figure 3 shows the layout in the 'before' and 'after' cases, along with morning peak-hour volumes for Northbound SH 360 at Division (SH 180) in Texas. ...
... Photogrammetry high points leads to faster scene clearance times, which are important in all states for travel and economy. Walters and Cooner (2001) referenced a Chattanooga, Tennessee police study which reduced clearance time of documented events by one hour. In this same report, agencies reported drawbacks of photogrammetry as being extended time necessary in the office to create a scaled diagram (Walters & Cooner, 2001). ...
