Corridor Signal Coordination Study Delaware Route 4N Corridor Signal Coordination Study SHORT-FORM REPORT Delaware Route 4 North Stanton Christiana Rd/Maryland Ave Newark/Wilmington, New Castle County, DE December 2013 Submitted to: 1 Corridor Signal Coordination Study Delaware Route 4N The Delaware Route 4 North (SR 4N) Corridor Signal Coordination Study is a joint effort between DelDOT and the University of Delaware. This is the fifth project performed in this format, known as the Delaware Signal Timing Enhancement Partnership (DSTEP). Basis for Selection This section of SR 4N was identified in coordination with WILMAPCO. SR 4N is a congested corridor in the WILMAPCO Congestion Management System Summary. Corridor Description The segment of SR 4N analyzed in this study includes a total of 29 signalized intersections. The entire corridor is approximately 5.78 miles, with speeds of 30-50 mph. The corridor was broken up into five groups in order to best coordinate the signals. Project Scope The project team collected data, made observations, performed traffic engineering analysis, and discussed signal operations strategies with the DelDOT TMC. In some cases, further studies and future work have been recommended at intersections. Otherwise, the emphasis of work has been the identification of signal timing enhancements such as phasing, coordination/offsets, splits/green times, cycle lengths, and time of day plans. Group 1 (intersections 1-6) Group 2 (intersections 7-11) Group 3 (intersections 12 & 13) Group 4 (intersection 14) Maryland Master (intersections 15-29) 2 Corridor Signal Coordination Study Delaware Route 4N With the following improvements, in concert with the signal timing adjustments recommended in the project’s “Signal Timing Action Packet”, DelDOT can look forward to improved operations along SR 4N in Newark/Wilmington, DE.

Further analysis of the intersection is needed to determine if a lead-lag left turn phase would decrease the LOS of the intersection. Benefit: Increased effectiveness of left turn movements. Intersection #23 – Pedestrian Facilities at DuPont Rd During an inspection of the intersection, it was found that some of the crosswalks were missing in part and the pedestrian signal heads need to be replaced. Benefit: Increased safety for pedestrians and improved pedestrian facilities. Intersection #25 – Pedestrian Facilities at Brookside/Mill Rd During an inspection of the intersection, it was found that some of the crosswalks were missing in part and the pedestrian signal heads need to be replaced. Benefit: Increased safety for pedestrians and improved pedestrian facilities. 3 Corridor Signal Coordination Study Delaware Route 4 North Summary of Study Group 1 (Intersections 1-6: SR 7 JP Morgan, Stanton Christiana Rd, Old Route 7, Delaware Park, Telegraph Rd, SR 7 Stanton) Group 2 (Intersections 7-11: Kiamensi Rd, Rothwell/First St Blvd, Glen Burne, MacArthur Dr, State St) Group 3 (Intersections 12 & 13: James St & Marshall St) Group 4 (Intersections 14: Latimer/Larch) Maryland Master (Intersections 15-29: Forest/Becker, Troy Ave, Fallon Ave, Boxwood Ave, Grier Ave, Champlain Ave, Summit Rd, Lorewood Rd, DuPont Rd, Race St, Mill Rd, Germay Dr, Clayton/Robinson, McGovern Terr, Broom St) Key Facts - Length: 5.78 miles, 30,519 feet +/- - Posted Speed Limit: 30-50 mph - Congested Corridor in WILMAPCO CMS Summary 1 Corridor Signal Coordination Study Delaware Route 4 North Intersection List # Intersection Permit Counted Current Group Status 1 SR 7 (JP Morgan) N366 2012 RT 7 (Stanton to AAA) - 2 Stanton Christiana N658 2012 RT 7 (Stanton to AAA) - 3 Old Route 7 N171 2012 RT 7 (Stanton to AAA) - 4 Delaware Park N019P 2009 RT 7 (Stanton to AAA) - 5 Telegraph Rd N289 2012 RT 7 (Stanton to AAA) - 6 SR 7 (Stanton) N225 2012 RT 7 (Stanton to AAA) - 7 Kiamensi Rd N318 2012 RT 4 Stanton to Newport - 8 Rothwell Dr N566 2012 RT 4 Stanton to Newport - 9 Glen Burne Dr N105 2012 RT 4 Stanton to Newport - 10 MacArthur Dr N357 2012 RT 4 Stanton to Newport - 11 State St/Westmont Rd N338 2012 RT 4 Stanton to Newport - 12 James St N395 2012 Newport 4 Corners Switch Groups 13 Marshall St N397 2012 Newport 4 Corners Switch Groups 14 Latimer/Larch N204 2012 Maryland Master Move off Master 15 Forest Dr/Becker Ave N203 2012 Maryland Master Move off Master 16 Troy Ave N202 2012 Maryland Master Move off Master 17 Fallon Ave N201 2012 Maryland Master Move off Master 18 Boxwood Rd N200 2012 Maryland Master Move off Master 19 Grier Ave N199 2012 Maryland Master Move off Master 20 Champlain St N198 2012 Maryland Master Move off Master 21 Summit Rd N197 2012 Maryland Master Move off Master 22 Lorewood Ave N196 2012 Maryland Master Move off Master 23 DuPont Rd N195 2012 Maryland Master Move off Master 24 Race St N154 2009 PM Maryland Master Move off Master 25 Mill Rd/Brookside Dr N194 2012 Maryland Master Move off Master 26 Germay Dr N372 2012 Maryland Master Move off Master 27 Clayton/Robinson Dr N477 2012 Maryland Master Move off Master 28 McGovern/Alban Dr N276 2012 Maryland Master Move off Master 29 Broom St N228 2012 Maryland Master Move off Master 2 Corridor Signal Coordination Study Delaware Route 4 North Existing TOD Plans Day Hour Min Plan Cycle Day Hour Min Plan Cycle 1 0 1 Free N/A 1 0 1 Free N/A 1 9 0 1/2/1 120 1 9 0 1/2/1 90 1 21 30 Free N/A 1 21 30 Free N/A 2 0 1 Free N/A 2 0 1 Free N/A 2 6 30 2/2/1 150 2 6 30 1/3/1 100 2 9 30 1/2/1 120 2 10 30 2/1/1 120 2 15 0 2/4/1 150 2 18 30 2/2/1 150 2 14 0 2/3/1 120 2 20 0 1/2/1 120 2 19 0 1/3/1 100 2 22 0 Free N/A 2 20 0 Free N/A Stanton Christiana Intersections 7-11: Kiamensi Rd (N318), N019P), Telegraph Rothwell Dr (N566), Glen Burne Dr (N105), MacArthur Dr (N357), State St (N338) Day Hour Min Plan Cycle Day Hour Min Plan Cycle 1 0 1 1/1/1 75 1 0 1 Free N/A 1 12 0 1/4/1 100 2 0 1 Free N/A 1 18 0 1/1/1 75 2 6 0 1/2/1 70 2 0 1 1/1/1 75 2 10 0 Free N/A 2 6 30 1/4/1 100 2 15 30 1/3/1 70 2 18 30 1/1/1 75 2 20 0 Free N/A shall St (N397) Intersection 14: Latimer (N204) Day Hour Min Plan Cycle 1 0 1 Free N/A 1 6 0 1/1/1 70 1 Intersections11 15-29:0 Forest Ave2/1/1 (N203), 90 1 Troy Ave13 (N202), Fallon0 Ave 1/1/1(N201), 70 2 Boxwood0 Ave (N200),1 Grier FreeAve (N199),N/A 2 Champlain6 Ave (N198),0 Summit1/1/1 Rd 70 2 (N197), Lorewood6 45Ave (N196),3/1/2 DuPont 120 2 8 15 1/1/1 70 Rd (N195), Race St (N154), Mill 2 11 45 2/1/1 90 Rd/Brookside Dr (N ), Germay Dr (N372), 2 13 0 1/1/1 70 2 Clayton/Robinson16 0Dr (N477),3/1/1 120 2 Mcgovern/Alban18 Dr0 (N276),
