Each application lists our priority ranking and includes accident reports and available traffic counts. The City of Salina would appreciate your consideration of these applications. If any additional information is needed, do not hesitate to call or e-mail. Sincerely, Eric M. Drager Traffic Engineer Cc: Shawn O'Leary Brad Johnson Encl.: 3 applications Our Mission is to Build and Maintain a Clean, Safe Community CITY OF SALINA BUREAU OF TRAFFIC ENGINEERING KANSAS DEPARTMENT OF TRANSPORTATION THACHER BUILDING, 217 SE FOURTH STREET, FOURTH FLOOR TOPEKA, KANSAS 66603-3504 PRIORITY NUMBER 1 INTERSECTION OF NINTH STREET AND CLOUD STREET EXISTING CONDITIONS Ninth Street is a major arterial with an average daily volume of 14,300 vehicles north of the intersection and 16,700 vehicles south of the intersection. North of the intersection, Ninth Street has a three lane cross section with a center two way left turn lane. South of the intersection, Ninth Street has a four lane cross section. Up until three hundred feet from the intersection, the cross section has two lanes in each direction. At the 300' point, the cross section transitions to three lanes northbound and one lane southbound. The three northbound lanes include a left turn lane, a through lane, and a right turn lane. Cloud Street is a collector street with an average daily volume of 6,600 west of the intersection and 9,100 east of the intersection. On both sides of the intersection, Cloud Street has a two lane cross section. As it approaches the intersection with Ninth Street, Cloud Street flares out to allow a separate left turn lane for both east and west bound traffic. The existing traffic control consists of a fully traffic and pedestrian actuated signal system with mast-arm mounted signals and protected/permissive left turn phasing in all directions. EXISTING PROBLEMS 1) Lanes on opposing sides of the intersection are all offset approximately six feet. This offset causes operational and safety problems. 2) The intersection is located approximately 650' south of the signalized intersection of Ninth Street and Claflin Avenue. At times, southbound vehicles will have a green at Claflin Avenue but will immediately have to stop due to vehicles backed up from Cloud Street. This results in a large number of rear-end accidents. A similar but less severe problem exists for northbound vehicles. PROPOSED POSSIBLE SOLUTIONS 1) Re-design the geometry of the intersection to correct the problem of offset lanes 2) Install a new controller system which will coordinate with the signal at Ninth Street and Claflin Avenue. REQUESTED IMPROVEMENTS 1) Modify the existing geometry of the intersection to remove the offsets. 2) Replace existing controller with a new controller that can coordinate with the traffic signal at Ninth Street and Claflin Avenue. 3) Replace signal poles and mast arms as needed due to changes in the intersection geometry Our Mission is to Build and Maintain a Clean, Safe Community CITY OF SALINA BUREAU OF TRAFFIC ENGINEERING KANSAS DEPARTMENT OF TRANSPORTATION THACHER BUILDING, 217 SE FOURTH STREET, FOURTH FLOOR TOPEKA, KANSAS 66603-3504 PRIORITY NUMBER 2 INTERSECTION OF BROADWAY BOULEVARD AND HAGEMAN AVENUE EXISTING CONDITIONS Broadway Boulevard is a major arterial. At the intersection with Hageman Avenue, there is an average daily entering volume of 6,100 vehicles from the northwest and 4,800 vehicles from the southeast. Broadway Boulevard is a four lane divided road with a center raised median. There are separate left turn lanes at the intersection with Hageman Avenue. Hageman Avenue is a two lane local street. At the intersection with Broadway Boulevard, the average daily entering volume from the south is 1,700 vehicles and the average daily entering volume from the north is 550 vehicles. The existing traffic control consists of a two-way stop with Broadway Boulevard as the uncontrolled street. The two streets are skewed at a forty-five degree angle. Hageman Avenue runs directly north and south. Broadway Boulevard runs northwest and southeast. There is an existing pedestrian bridge which crosses the southeast leg of Broadway. EXISTING PROBLEMS 1) This intersection suffers from sight distance problems. The skew angle of the streets causes drivers on Hageman Avenue difficulty in seeing an approaching vehicle on Broadway Boulevard. The existing pedestrian bridge also creates a sight obstruction which can not be easily moved. The combination of factors causes numerous right-angle collisions. PROPOSED POSSIBLE SOLUTIONS 1) The intersection is approximately 600' southeast of an existing signalized intersection at Cloud Street and Broadway Boulevard. Due to the close vicinity, Broadway Boulevard and Hageman Avenue should not be signalized. Geometric changes are the only real possibility. 2) Build a raised median and prohibit left turns in all directions. 3) Create a cul-de-sac on either one or both legs of Hageman Avenue and eliminate access to Broadway Boulevard all together. 4) Remove the existing pedestrian bridge over the south leg of Broadway Boulevard. 5) Redesign the intersection geometry so that the south leg of Hageman Avenue intersects with Broadway Boulevard at a right angle. REQUESTED IMPROVEMENTS 1) Close the north leg of Hageman Avenue and create a cul-de-sac. 2) Remove the existing pedestrian bridge over Broadway Boulevard. 3) Adjust the horizontal geometry of the south leg of Hageman Avenue so it intersects at a right angle with Broadway Boulevard. Move the median break on Broadway Boulevard to correspond with the new alignment.

At this location, Interstate 135 carries an ADT of approximately 18,000 vehicles. The ADT for the northbound exit ramp to Crawford Street is 3,300 and for the southbound exit ramp is 2,850. The entering volume for eastbound traffic on Crawford Street is 2,000 vehicles and for westbound traffic is 6,170 vehicles. Both exit ramps are marked as a single lane and are controlled by Stop signs at Crawford Street. The ramps widen at the intersection with Crawford Street to a distance of about sixty feet. Crawford Street is uncontrolled. Crawford Street to the west of the interchange is a two lane undivided road which widens to a four lane undivided just as it arrives at the southbound ramps. Crawford Street continues as a four lane undivided road through the interchange and to the east. EXISTING PROBLEMS 1) Vehicles exiting from Interstate 135 often do not see the Stop signs in time. This causes rear-end accidents with vehicles already stopped and right angle collisions with vehicles traveling on Crawford Street. 2) There is an existing crest vertical curve over Interstate 135 on the Crawford Street bridge. Vehicles on the northbound exit ramp waiting at the Stop sign have a difficult time determining when it is safe to turn onto Crawford Street. 3) There are two side street entrances on the north side of Crawford Street approximately 230 and 350 feet east of the northbound ramps. These are Westport Road and Graves Road respectively. Heavy volumes and the lack of a median on Crawford Street make left turns in and out of these side streets hazardous. PROPOSED POSSIBLE SOLUTIONS 1) Install a traffic signal at both ramps of the interchange of Interstate 135 and Crawford Street. Existing data indicate that the interchange meets Warrants 1,2,7, and 8 for the installation of a traffic control signal from the Manual on Uniform Traffic Control Devices. A traffic signal would alleviate accidents at the interchange as well as creating gaps in traffic along Crawford Street. REQUESTED IMPROVEMENTS 1) Install a traffic signal at both ramps of the interchange. 2) Install a controller that can coordinate with the signal at the intersection of Crawford Street and Centennial Road to provide gaps for traffic that need access to and from Westport Road and Graves Road.
