31 INTRODUCTION A cornerstone of this synthesis report was a comprehensive sur- vey of urban areas in North America. Information was sought on agency perceptions, policies, and characteristics of different transit preferential treatments that they have applied to their bus and light rail/streetcar systems. This has been the first known systematic survey of transit agencies conducted on this topic to date. In addition, a parallel survey was sent to traffic engineer- ing jurisdictions that the transit agencies typically work with to plan, design, construct, operate, and maintain transit preferen- tial treatments. The intent was to obtain insights from traffic engineers on their perceptions and policies related to transit preferential treatment development. The mechanism chosen for agency input was a web survey. The survey was initially sent to transit agencies, which then identified one or more appropriate contacts in the traffic engi- neering jurisdiction they deal with, and these individuals were sent a separate survey. The traffic engineers were also asked to add data on traffic conditions in the tabular sum- mary of individual preferential treatment characteristics pro- vided by the transit agencies. A total of 80 urban areas in the United States and Canada were included in the transit/traffic survey effort—including 50 transit agencies operating just bus and another 30 oper- ating bus and streetcar and/or light rail. The transit survey responses received (52) were helpful in identifying overall trends with respect to transit preferential treatment application. The supplemental survey of traffic engineering jurisdictions in these urban areas was conducted to obtain traffic engineers’ insights on transit preferential treatments. An added 12 juris- dictions responded to this survey. The total of 64 responses were received, an 80% response rate. TRANSIT AGENCY SURVEY This chapter summarizes the responses of the transit agency survey covering transit preferential treatments. The transit/ traffic survey questionnaires and agency responses are included in Appendix A. Between December 20, 2008, and Febru- ary 20, 2009, a total of 80 urban areas in the United States and Canada were invited to respond to the survey. This included all 30 urban areas that today have both fixed-route bus and light rail and/or streetcar service, and another 50 agencies that pro- vide only bus service. These were most of the larger urban areas in the United States and Canada. Of those transit agen- cies that were sent the survey, 52 responded; while an addi- tional three agencies indicated that they do not currently have any transit preferential treatments. This response level was achieved following three separate solicitations to respond to the survey. For those 30 systems that operate both bus and light rail and/or streetcar systems, 21 responded. For the 50 bus- only agencies surveyed, 31 responded. The 52 responding agencies are indicated on the map shown as Figure 27 and in Tables 2 and 3, grouped by transit service type—bus and light rail/streetcar systems versus bus-only systems. These tables also show the Vehicles Operated in Max- imum Service, obtained from the 2007 edition of the National Transit Database. Note that Vehicles Operated in Maximum Service were not available for Canadian transit agencies. Figure 28 provides information on the types of transit pref- erential treatments (bus and LRT/streetcar) that have been implemented by the responding transit agencies. Percent- ages are calculated with respect to the number of responding agencies. The most popular treatment is TSP, which has been implemented by two of every three respondents. Limited stops and queue jump/bypass lanes have also been implemented by more than half of the responding agencies. Table 4 summarizes the type and number of transit prefer- ential treatments in different urban areas where specific treat- ment information was provided from the survey. It should be noted that the list is not all inclusive, as some transit agencies did not identify all of their treatments. Also, for TSP, some agencies identified the number of individual intersections with priority, whereas others only identified the specific corridors where TSP is applied, without identifying the specific number of signals in each corridor with priority. Agencies were then asked to provide information about each transit preferential treatment within their jurisdiction. Information requested included the location and type of treatment, ridership and transit vehicle headway, and traffic information such as the average daily traffic and level of ser- vice. Details of these individual treatment responses are pro- vided in Appendix B. A total of 197 individual treatments were recorded. Transit agencies were asked to provide information on any “warrants” applied when considering transit preferential treatments. Most agencies that responded provided general criteria or measures applied, but mainly did not identify CHAPTER FOUR SURVEY RESPONSES

34 specific numerical warrants. Tables 5 and 6 relate to the war- rants for transit preferential treatments provided by survey respondents for bus and LRT/streetcar service, respec- tively. The criteria/warrants are grouped by treatment, using the same abbreviations as those used in Figure 28. Common themes throughout the responses included rider- ship, safety, and delay considerations, as well as reliability and level of service. The popularity of TSP reflects its flexibility owing to the many different types of priority that may be employed. Priority types are typically classified as either active, where the transit vehicle initiates a request for priority, or passive, where the sys- tem is optimized for transit but individual vehicles do not make any requests. Figure 29 identifies the extent of use of different active priority types: unconditional, conditional if vehicle is behind schedule, conditional based on number of on-board pas- sengers, and other conditional strategies. Percentages are based on the number of agencies implementing TSP; for example, more than half of all agencies that have implemented TSP apply unconditional priority at some location in their networks. No agency reported using the number of on-board riders as a met- ric for granting priority, even though ridership was commonly cited as a warrant for implementing TSP. This is perhaps not surprising, as automated person counters are not yet broadly used on transit vehicles. Bus Transit Agency MT EL TSP STS QJ/BL CE LS O Capital Metro Transp. Auth.

FIGURE 29 Active TSP types (bus and LRT/streetcar). Figure 30 provides similar data for passive TSP treatments. Nearly half of all respondents implementing TSP indicated that they employ signal coordination to provide priority to transit vehicles. Some of the “other” passive treatments appear to be related to signal timing as well. Traffic agencies were also asked about control of priority for both bus and LRT/streetcar implementations, which is illus- trated in Figure 31. For the purposes of this survey, centralized control was considered to mean that priority decisions are made at some centralized system control center, whereas distributed was considered to imply that decisions are made locally at the cabinet controller where the request was received. Of those agencies responding to the survey, responses were split almost equally between centralized and distributed methods of con- trol for bus transit, with one agency reporting that they do not implement TSP. For LRT/streetcar systems, although four responding agencies appear to implement some sort of TSP for their systems, only one agency noted that it uses a distrib- uted approach to grant priority requests. Transit agencies were asked to indicate what roles they played in the process of developing transit preferential treat- ments. This information is presented in Figure 32. From the figure, one notices that transit agencies tend to be more involved in the early phases of implementation in identifying and locating treatments and become less involved in the later stages, with the exception of monitoring performance. This is expected because local traffic engineering jurisdictions have control over the signal and roadway system and thus are typi- cally more involved in construction and operations and main- tenance of treatments. The increase in transit agency involve- ment in monitoring performance is not surprising because transit agencies tend to have the most to gain from this activ- ity and there are now tools such as AVL and APC to collect data on transit operations.

The survey asked a question on whether or not transit agencies have a comprehensive transit preferential treatment program in place to guide the development and implemen- tation of transit preferential treatments. The vast majority (almost 80%) indicated that they do not have such a program, and that transit preferential treatments when developed occur on a case-by-case basis. Those that do have a program in place tend to be larger agencies such as the Metropolitan Transportation Authority in New York City, King County Metro in Seattle, and the Municipal Transportation Agency (MUNI) in San Francisco. Transit agencies were also asked if they have any agree- ments with a traffic agency. A majority of agencies (56%) have such an agreement, although several agencies indicated that the agreements are somewhat informal in nature. This result is encouraging because it demonstrates a high-level of cooperation between transit and traffic agencies for mutual benefit. Again, larger agencies are more likely to have a comprehensive program, although some smaller agencies did as well. Sample construction and operations and maintenance agree- ments related to TSP implementation were received from King County Metro in Seattle; Community Transit in Snohomish County, Washington; and TriMet in Portland, Oregon. These agreements are included in Appendix C. Similar to the previous question, more than half of all agen- cies (56%) reported undertaking some sort of public input process before or during the implementation of a treatment. This result also is encouraging, because although transit preferential treatments may not be as visible to the public as new routes or transit vehicles, they do nevertheless improve

41 the experience of transit riders. A list of the methods employed by agencies to garner public input is provided in Table 7. The most common forms of public input are meetings/open houses and mailings. TRAFFIC AGENCY SURVEY Transit agencies were asked to provide contact information for traffic agencies with which they work, so that the agen- cies could verify information for the individual transit pref- erential treatments, as well as respond to a separate traffic agency survey. The following sections summarize the results of the traffic agency survey. The traffic agency survey ques- tionnaire is in Appendix B, with detailed responses for each agency also provided in Appendix B.

Generally, the traffic agencies verified the transit agency responses in indicating they have been more involved in the latter phases of implementation, in particular operations and maintenance. Again, the traffic agencies rely on the transit agencies primarily for identifying and locating preferential treatments. In their responses to monitoring the performance of treatments, the traffic agencies indicated a higher response owing to their focus on monitoring impacts on general traffic conditions of preferential treatments. Design and construction again appear to be shared functions. None of the responding agencies indicated they have no role whatsoever in transit pref- erential treatment development and monitoring. Traffic agencies were asked about their perceptions of the impacts of various transit preferential treatments on general traffic operations. These perceptions were qualified as major, mild, or negligible, as identified in Figure 34. Not surpris- ingly, the two treatments considered by many to have a major impact were median transitways and exclusive lanes. These two treatments take the most ROWs and have the greatest impact on available general traffic capacity. Most remaining treatments were considered to have minor impacts. This is consistent with the relatively slight timing modifications asso- ciated with TSP (and its typical application at intersections operating under capacity), and the limited impact on through traffic with queue jump/bypass lanes. Limited stops had a nearly equal perception of minor and negligible impacts,

Traffic agencies were asked to provide geometric informa- tion concerning the minimum width of median transitway lanes and the minimum length of queue jump/bypass lane lengths. These data are presented in Table 8. One-way median transit- way minimum widths are for the most part between 10 and 12 ft, whereas for two-way transitways the range is generally greater by a factor of 2 or more. Minimum queue jump/bypass lane lengths varied greatly, but centered mostly around 100 ft. Traffic agencies were asked to provide details concerning their TSP operations. Tables 9 and 10 present the controller hardware and TSP software used, if identified, for bus and LRT/streetcar applications, respectively. Generally, cities that have both bus and LRT/streetcars employ the same controllers for both. It is clear that there are a variety of hardware and soft- ware providers to choose from. Tables 11 and 12 indicate the types of TSP applied for both bus and LRT/streetcar, respectively. All responding agencies with TSP use early green and green extension to provide pri- ority. Few agencies implement the other approaches, which may tend to be more disruptive, especially when considering coordinated signal systems. It is also interesting to note that the Utah DOT applies activated transit phases and phase rota- tion and insertion for LRT/streetcars, but not for buses. Tables 13 and 14 identify the detection methods used for TSP calls for buses and LRT/streetcars, respectively. The most common method is optical/infrared, followed by induc- tive loop sensors. No agency reported using GPS despite its increasing affordability; however, there are GPS applications in certain cities that did not respond to the survey. Continuing with TSP data collection, traffic agencies were asked whether they monitor and record TSP events or not. Only one-third of the agencies collect such information. When asked further about which events are monitored, all agencies that monitor events collect data concerning proper vehicle detection and equipment function, as displayed in Figure 35. Only one of the four agencies monitoring data indicated that they monitor use of queue jump/bypass lanes. However, this could in part be the result of other agencies not having any queue jump/bypass lanes to monitor. Furthermore, of the agencies that record data, all record the number of possible and actual TSP events, as well as their duration. This is promising as it demonstrates a contin- ued desire to maintain and improve TSP by these agencies. Traffic agency respondents were also asked about special actions taken for any of the transit preferential treatments, such Minimum Median Transitway Width (ft) Agency One-Way Two-Way Minimum Queue Jump/Bypass Lane Length (ft) City of Eugene, OR 120 City of Everett, WA 11 22 100 City of Lynnwood, WA 9 20 80 City of Ottawa, ON 14 32 70 Los Angeles DOT 10 14 Mn/DOT 10 300 Philadelphia Streets Department 12 24 Utah DOT 30 TABLE 8 LANE WIDTH AND LENGTH TREATMENT

45 as special signing, striping, or design. Table 15 provides a list of these special treatments by agency. Interesting treatments include rail-type signals being used in a block operation for the Eugene BRT and painting of exclu- sive bus lanes in Ottawa. Traffic agencies were asked whether there is an inter- governmental agreement with the transit agency concerning transit preferential treatments and, if so, whether there are any enhancements that would be desirable. Four agencies indicated there was no agreement: • WSDOT • Los Angeles DOT • City of Everett, Washington • Sacramento County DOT, California Clarification of, or the desired enhancements to, existing transit preferential treatment intergovernmental agreements for the remaining eight agencies are provided in Table 16. Finally, traffic agencies were asked to indicate their level of support for each of the transit preferential treat- ment types. The results are provided in Figure 36. In gen- eral, most types enjoy major support. Similar to the level of impact, median transitways and exclusive lanes have lower levels of major support than the other types. It is interesting to note that both curb extensions and special turn signals have higher levels of “no support” than exclu- sive lanes, even though exclusive lanes generally have greater impacts and cost more. Both TSP and limited stops did not receive a single vote of “no support” from the respondents, indicating a high level of acceptance of these approaches. Agency Treatment City of Bellevue A signal priority loop is marked as “Bus Detector” with a blue light to let operator know the bus has been detected. City of Eugene Queue jumps have separate signal heads and lanes. Exclusive bus lanes are signed appropriately. Rail type signals are used in block protected bi-directional exclusive lanes. City of Lynnwood Signs indicate: Right Lane Must Turn Right Except for Bus City of Ottawa Bus signal signing, experiment with painting lanes red Los Angeles DOT Signing and striping modifications to accommodate for far-side bus stops Minnesota DOT Signs for the bus shoulders and for HOV bypasses. Special diamond striping and overhead changeable message signs for the HOT (high-occupancy toll) lanes Philadelphia Streets Department Only where there is a separate marked area in the center of Girard Avenue for the Route 15. Utah DOT At all sites where left turns are allowed from a parallel movement across LRT tracks there are blank-out warning signs that are lit with an image of a train when a train is approaching the intersection. Additionally, at sites where one of two dual left-turn lanes is shared with the LRT trackway, there are blank-out signs warning motorists to stay off the track when a train is approaching from the rear. The signs are not lit if vehicles are already in the lane.

46 Agency Intergovernmental Agreement Enhancements City of Bellevue Each agreement is more project-specific, and longer ranging and lacking consistency. They appear to be highly variable depending on capital funding available and project manager. City of Eugene The agreement is informal and based on mutual benefit. City of Lynnwood The only comment is that the city has not had any discussions to determine agency-wide desires. There is some desire to add training for central software operation to include analysis and reporting. City of Ottawa Define the number of buses required for treatment levels. City of Tacoma Public Works Not sure Minnesota DOT (Mn/DOT) The real answer is “no,” not a written agreement. However, there is an interagency working group called Team Transit that develops ideas and is chaired by Mn/DOT. The working group has developed nearly 300 miles of bus shoulders and many other transit advantages and appears to work well. There is a written policy to provide transit advantages applied to freeways and expressways as appropriate (also in statute). Philadelphia Streets Department For each project there is an agreement. These three were pilots. Utah DOT The agreement at present is informal but is undergoing review with the transit agency and other traffic agencies. It will then be formalized. One enhancement desired by all the participating agencies (traffic and transit) is that no more sites will be constructed with shared trackway/left-turn lanes, because they have been problematic.
