2 Administered by ITS at UC Berkeley Administered by ITS at UC Berkeley Funded by OTS Funded by OTS Two Evaluators – Engineer and Law Enforcement Officer Two Evaluators – Engineer and Law Enforcement Officer Typically initiated by an agency Typically initiated by an agency Public Works or Police/Sheriffs Department Public Works or Police/Sheriffs Department Process begins with completion of an Intake Form Process begins with completion of an Intake Form ABOUT THE TSE PROGRAM

3 Identifies the requesting agency Identifies the requesting agency Provides contact information of the participating staff members Provides contact information of the participating staff members Lists the available information Lists the available information Identifies the primary focus areas of the evaluation Identifies the primary focus areas of the evaluation May include attachments such as maps or aerial photographs May include attachments such as maps or aerial photographs Form used by evaluators to establish contact with agency staff Form used by evaluators to establish contact with agency staff Dates for two-day site visit established and confirmed by ITS Dates for two-day site visit established and confirmed by ITS INTAKE FORM

4 Top ten crash locations based on SWITRS data Top ten crash locations based on SWITRS data Top five crash corridors based on SWITRS data Top five crash corridors based on SWITRS data Pedestrian and bicycle circulation Pedestrian and bicycle circulation School circulation issues School circulation issues Cut through traffic on residential streets Cut through traffic on residential streets Evaluation of previously identified solutions (roundabouts) Evaluation of previously identified solutions (roundabouts) Evaluation of recently constructed improvements Evaluation of recently constructed improvements Traffic signal timing and phasing Traffic signal timing and phasing FOCUS AREAS - ENGINEERING

6 Identified by law enforcement evaluator Identified by law enforcement evaluator SWITRS data or Crossroads if used by agency SWITRS data or Crossroads if used by agency Based on total number of crashes – not crash rates Based on total number of crashes – not crash rates Types of collisions and citations issued Types of collisions and citations issued Data sorted prior to site visit Data sorted prior to site visit Used during site visit to analyze locations Used during site visit to analyze locations Used after site visit to prepare the final report Used after site visit to prepare the final report HIGH CRASH LOCATIONS

7 Takes place over a two day period Takes place over a two day period Begins with kick-off conference call (This is new) Begins with kick-off conference call (This is new) Engineer evaluator tours city to analyze high crash locations Engineer evaluator tours city to analyze high crash locations Engineer also evaluates other issues such as schools Engineer also evaluates other issues such as schools Law enforcement officer meets with agency officers Law enforcement officer meets with agency officers Exit meeting held on second day to report preliminary findings Exit meeting held on second day to report preliminary findings Final report prepared based on exit meeting discussions Final report prepared based on exit meeting discussions SITE VISIT

8 Crosswalk with two white lines Broadside collisions due to restricted sight distance and Yield sign controls on two approaches

9 Schools have presented special challenges

10 Roads with no turn lanes or bike lanes need to be put on a diet!

11 Four travel lanes restriped to two lanes, left-turn lane and bike lane to reduce collisions (aka Road Diet)

12 Scramble pattern for pedestrians

13 San Luis Obispo, CA Scramble pattern for bicyclists

14 Better placement of gates would also protect peds and bikes

15 Warning displays at light rail station pedestrian crossing

16 Increased use of blank out signs

17 Truck apron is 7 high – too severe – generating complaints from bus passengers

18 IDENTIFY COUNTERMEASURES

19 PEDESTRIAN COLLISION COUNTER MEASURES Compliance with CAMUTCD Compliance with CAMUTCD Upgrade markings Upgrade markings Improved signage Improved signage Positive traffic control/warning devices Positive traffic control/warning devices Crosswalk relocations Crosswalk relocations Crosswalk removals Crosswalk removals Traffic calming treatments Traffic calming treatments

20 Invisible marked crosswalk
